Mikel Arteta was unable to provide excuses on Sunday, after Arsenal crashed out of the FA Cup with a 1-0 defeat to Nottingham Forest.

"We are out of the competition and we have to apologise."

Arsenal have won the FA Cup a record 14 times, with their last triumph coming in Arteta's first half-season in charge. But while they will lament being on the end of a giant-killing, they have the chance to bounce back from only their second third-round exit in the past 26 seasons when they face Liverpool at Anfield on Thursday in the first leg of a semi-final in England's other major domestic cup competition.

Initially, the Anfield fixture of this EFL Cup tie was due to be played second but Liverpool's coronavirus crisis, which Jurgen Klopp revealed was ultimately down to several false-positives within the squad, led to the postponement of the first leg at Emirates Stadium, originally set to be played on January 6.

The Gunners lost 4-0 at the home of the Reds in November's Premier League meeting, as Arteta's men were dealt a harsh dose of reality after a 10-match unbeaten run across all competitions.

A further 10 games have passed since then, with Arsenal losing four and winning six.

With Pierre-Emerick Aubameyang having been stripped of the captaincy and ostracised before travelling away for the Africa Cup of Nations, Arteta has once again turned mostly to youth as he looks to continue to grow a new "culture" at Arsenal, who sit fourth in the league.

Claiming some measure of revenge at Anfield could just prove Arteta's plan is the solution for long-term success, and four players seem crucial to that blueprint.

Super-sub Smith Rowe

Aubameyang's omission for a breach of club rules brought unnecessary noise in December, though results were not immediately impacted. With the 32-year-old not playing since December 6, Alexandre Lacazette has stepped in to spearhead Arsenal's attack, but behind him Arteta has an abundance of talent to choose from.

Emile Smith Rowe started the season brilliantly, though has only started one league game since November. That has not stopped the 21-year-old from being effective, however, with three of his eight league goals this season coming from the bench in recent wins over West Ham, Leeds United and Norwich City.

Smith Rowe has only played 63 league minutes since featuring for 70 in the December 2 loss to Manchester United, meaning he averages a goal every 21 minutes in that period. 

Asked about Smith Rowe's game time before the defeat to Forest, which the midfielder missed altogether, Arteta explained he had been carrying an injury, one which also means he is a doubt for Thursday's clash.

"The only reason that changed the dynamic was that [injury], and obviously now there are others who are doing well and have been performing well. That changed the situation, but I am very happy with him," Arteta told reporters, before adding that competition for places can only be positive.

"This is why we need that, we raise the level. Each player raises the level of the player next to him, and this is how you evolve as a team, how you create a culture around the team."

Few could say Smith Rowe isn't embracing that "culture", with his recent hot streak off the bench reflecting a commendable attitude.

Martin the maestro

One of the "others" Arteta was referring to will surely be Martin Odegaard, who signed permanently from Real Madrid following a bright loan spell last season. Given the Norway international burst onto the scene at the age of 15 in 2014, becoming the youngest footballer ever to play in his homeland's top tier, it would be easy to forget he has only just turned 23.

Only Bukayo Saka (38) has created more chances than Odegaard (34) in Arsenal's squad in all competitions this season, with the midfielder topping that metric per 90 minutes when it comes to players to have featured over two times, producing 2.1 opportunities on average.

His eight direct goal contributions ranks him fifth in the squad while his shot conversion rate of 18.2 is good for a midfielder. Indeed, only the outstanding Smith Rowe, who has converted 32.1 per cent (nine goals) of his 28 attempts can boast better among Arsenal's midfield contingent.

Yet with Smith Rowe's recent spell as an impact player, Odegaard has started behind the striker in Arsenal's 4-2-3-1, his eye for a pass and knack of finding space on the edge of the area a key facet to some slick attacking play.

That playmaking ability was on show in the 5-0 thrashing of Norwich on Boxing Day, with Odegaard providing the assists for Arsenal's opening two goals and a key role in their final strike.

While Odegaard (33) has had fewer touches in the opposition box than left-back Nuno Tavares (35) and completed just 10 dribbles compared to Smith Rowe's 23 and the team-leading Saka's 27, no Arsenal player has attempted more passes in the opposition half than Odegaard (523), with 80.9 per cent (423) proving successful.

Odegaard's ability to keep Arsenal in possession with neat and incisive passing has been crucial for the Gunners. Indeed, only centre-backs Ben White (933) and Gabriel Magalhaes (822) have found a team-mate on more occasions than the playmaker (703).

Wing wizards

Flanking Odegaard (or Smith Rowe), Saka and Gabriel Martinelli both head to Anfield in superb form. While Saka scored the opener in the 2-1 defeat to City on New Year's Day, Martinelli has directly contributed to six goals from 18 appearances.

Martinelli's devastating turn of pace was on show in a 4-1 rout of Leeds United last month, though the Brazilian flyer missed a golden chance to put Arsenal back in front in their defeat to City, slicing wide of an open goal – if we're being generous, perhaps he was put off by the referee. Still, he should have scored.

Nevertheless, his four goals have come from an xG value of 4.2, putting him just about on par based on the quality of chances he has been provided with, though that is in contrast to Saka.

The England winger's tally of seven goals is second only to Smith Rowe (nine), yet they have come from 4.6 xG, suggesting the 20-year-old is finishing chances the average player wouldn't ordinarily be expected to convert.

For example, his swept effort low into the corner against City was only the seventh-best chance of the game, while a wonderful solo strike at Norwich (his second goal of the game) registered an xG of just 0.03 – essentially, this translates to a three per cent likelihood of scoring.

Saka also leads the way for big chances created (defined by Opta as an opportunity from which a player would reasonably be expected to score) with eight, three more than any of his club-mates, and only Nicolas Pepe has provided more assists (five to four).

Not only is Saka already a proven creator of opportunities, but he is now putting them away with unerring accuracy.

Arsenal were dealt a harsh lesson on their last visit to Anfield, but with a second leg at home to look forward to and with Liverpool missing key duo Mohamed Salah and Sadio Mane, Thursday could see Arteta's counter-attacking youngsters thrive, with a north London derby against Tottenham up after that.

Even if it again proves a step too far, there's no doubt the future is bright.

When the Tampa Bay Buccaneers traded for Rob Gronkowski back in April 2020, it was tough to picture the future Hall of Fame tight end having a substantial impact.

After all, Gronkowski had appeared to have spent his last reserves in Super Bowl LIII when he hauled his clearly ailing body downfield and made a diving grab for a 29-yard fourth-quarter reception that set up the New England Patriots' only touchdown of their 13-3 win over the Los Angeles Rams.

It was a catch that at the time served as a spectacular last ember of an incredible career, but the Bucs put stock in Tom Brady's belief that Gronkowski's fire to deliver at the highest level still burned brightly, and they have been emphatically vindicated.

He caught seven touchdowns in the 2020 regular season, but he once again saved his best for the grandest stage with a dominant two-touchdown performance in the Bucs' Super Bowl LV rout of the Chiefs.

And, with Tampa Bay shorn of most of their depth at the wide receiver position, there will be an even greater emphasis on Gronkowski to rise to the occasion as the Bucs attempt to defend their title.

His numbers from a surprisingly efficient 2021 suggest he is more than up to the task.

Running out of receiving weapons

Last year, opposing defenses weren't able to consistently dedicate special attention to Gronkowski, such was the wealth of options at Brady's disposal.

They went into the previous campaign's postseason with Mike Evans, Chris Godwin and Antonio Brown at receiver as well as having Gronkowski at tight end.

Evans remains and remains an extremely gifted number one receiver who perhaps does not get the credit he deserves for his hugely impressive consistency.

In Week 18, Evans surpassed 1,000 yards receiving for the eighth successive year, an NFL record for the longest streak to start a career.

He leads all wideouts (min. 100 targets) in burn percentage, which measures how often a receiver wins his matchup with a defender on a play where he is targeted. Evans has won 75.2 per cent of those matchups this season, while he is also first among receivers who meet that threshold with a big play rate of 43.1 per cent.

However, Brown's departure from the team leaves the Bucs without a receiver tied third for burn yards per route (4.0) among receivers with at least 50 targets.

Godwin is on the shelf with torn ligaments in his knee, robbing Tampa of another top pass-catcher who on the list of wideouts with triple-digit targets trails only Evans, Tyreek Hill and Stefon Diggs with his burn rate of 70.4.

Their absences place Gronkowski's ability to produce elite play at tight end into sharper focus and his efforts at the age of 32 should give great encouragement to Tampa.

Gatecrashing the elite

Gronkowski was long since seen as the gold standard at the tight end position. A mismatch as a receiver and a tremendous blocker, peak Gronk is the blueprint for modern-day NFL tight ends.

But when he re-entered the league after a retirement that lasted only one season, a new order of top tight ends had been established.

George Kittle and Travis Kelce are regarded as the best of the best at tight end, with Darren Waller a tick below that duo. This season, Mark Andrews and Dallas Goedert have taken leaps to threaten to join the elite.

Yet in several metrics, it is Gronkowski who stands above that group at the top of the pile.

Gronkowski's burn rate of 72.1 per cent trails only Goedert and Kelce among tight ends with at least 25 targets. However, he is first in burn yards per target (13.00), burn yards per route (3.5) and big play rate (45.7 per cent).

Simply put, no tight end in the NFL has done a better job at creating separation and turning his targets into explosive plays than Gronkowski, whose rapport with Brady shows no sign of dissipating.

Indeed, when he targeted Gronkowski in the regular season, Brady had a passer rating of 113.6. To put that into context, the best overall passer rating this season was Aaron Rodgers' 111.9.

When Brady needed a big play in his final Super Bowl with the Patriots, he turned to Gronkowski, and it was their combination that was arguably the most crucial offensive aspect of the defeat of the Chiefs last year.

With Brown gone and Godwin out, the cupboard is not as well-stocked for the Bucs heading into this postseason, meaning if Brady is to claim ring number eight, he will again need to turn to the man whose renaissance in Tampa is arguably as impressive as his own ceaseless brilliance.

Twelve months ago, Dani Alves was in training with Sao Paulo in between a disappointing draw with Athletico Paranaense and 1-0 home defeat in the San-Sao derby to Santos.

At the same time, Vinicius was in the midst of a Real Madrid goal drought that began in late October and didn't end until March 1.

Now, they are preparing to face each other in the Supercopa de Espana semi-final, with Alves astonishingly back at Barca and – perhaps even more surprising – Vinicius probably one of the two best players in LaLiga.

It's fair to say that, at this point last year, there were growing concerns Vinicius simply wasn't going to be the player many had hoped or predicted.

While he was still only 20, he didn't seem to have developed a great deal since joining from Flamengo in 2018. If anything, he looked as though he was in reverse, and rumours were beginning to swirl regarding his future.

It was a little like when Samuel L. Jackson's Mace Windu in Star Wars doubts the prophecy that Anakin Skywalker is 'the One' to destroy the Sith.

Yet, Vinicius (SPOILER ALERT) succeeded where Anakin failed, the Brazilian managing to get himself back on the right path. In terms of decisiveness, he looks unrecognisable now, so ruthless that you'd suggest he was more machine than man – just without the helmet and Darth Vader's asthmatic problems.

First and foremost, Vinicius' haul of 12 goals is already three times his previous best in a single LaLiga season, and he's still got almost half a campaign left.

Undoubtedly Carlo Ancelotti's trust will be playing a part. Zinedine Zidane never quite gave the impression he had absolute faith in Vinicius, but the Italian has been unwavering in that regard practically ever since he got the job for a second time.

But Vinicius deserves the most credit.

He's showing much more maturity in his game. He's gone from being the most frustrating player on the pitch to very often being the most decisive.

His expected goals (xG) per 90 minutes is up to 0.49 from 0.3, which suggests he's generally getting into better positions than before – but perhaps even more importantly, though connected to that, is the fact he's averaging 0.67 goals over the same period.

Last season that figure was just 0.14, roughly half his xG, evidence that his decision-making and composure were at a pretty low level.

Vinicius is creating chances more frequently as well (1.9 per 90 mins, up from 1.5), but his biggest improvement is definitely in his decisions in front of goal.

Of course, outperforming xG can be a sign of good fortune, so some might suggest his form isn't sustainable – we won't know whether that's the case for a while yet.

But even when you disregard that, the improvement he's shown is massive. He's gone from wasting chances he shouldn't, to scoring chances he shouldn't.

His first goal in the recent 4-1 win over Valencia was an interesting exhibition of his new-found striker's instinct. Not only did he continue his run after offloading to Karim Benzema, he then made his own luck when bundling the ball through a crowd before nonchalantly passing into the bottom corner.

While maybe not an astounding goal in isolation, it's difficult to imagine that passage going the same way last season. Confidence breeds confidence, and he looks almost unstoppable.

With that in mind, the man he'll come up against on Wednesday will presumably be getting himself pumped up for a real challenge.

Of course, Alves has been there, done that, got the T-shirt and wore the hat. If we go back to the bad Star Wars analogies, Alves is Obi-Wan Kenobi. You thought he was gone for good but returns when you need him most.

This will of course be his first Clasico since returning to the club in November, answering Barca's call when all they could afford were free signings.

As much as anything, Wednesday's game should provide Xavi with understanding as to what the 38-year-old's ceiling is.

It's unlikely he'll be fazed about the prospect of tussling with Vinicius, though he'll be aware of the standard his compatriot is now playing at.

If Vinicius can be kept quiet, Barca's chances of success will increase exponentially, and it's by no means outlandish to suggest this game could be a turning point in their season, as Xavi noted in his pre-match news conference.

With a recent bank loan allowing them to sign Ferran Torres and president Joan Laporta declaring Barca are "back", all of a sudden the outlook isn't so gloomy, particularly now they're through the worst (they hope) of an injury and coronavirus outbreak crisis.

Xavi's brought through several talented young players already, and then there were injured 'wonderkids' Ansu Fati and Pedri waiting in the wings. They look set for important roles over the rest of the season and beyond – you might even suggest there's plenty of cause for optimism at Camp Nou.

The Supercopa offers a chance to really consolidate the growing positivity, and success in the Clasico might indicate Barca are genuinely back.

We may only be a week into 2022, but the first major international football tournament of the year is on the horizon, with the Africa Cup of Nations kicking off on Sunday.

It's been a long time coming as well – it was initially due to take place in June and July 2021 but was brought forward to January 2021 due to concerns about the weather. It then had to be pushed back a year due to the coronavirus pandemic.

Of course, fans and teams have had to put up with the usual posturing from those at certain clubs regarding the inconvenience of relinquishing players in the middle of the season, but despite that there remains a healthy selection of big names.

In fact, given the standard the likes of Mohamed Salah, Sadio Mane, Riyad Mahrez and Achraf Hakimi usually play at, some might even argue this is one of the highest-quality groups of players to feature at a single AFCON.

But the beauty of every international tournament is that there's more to them than the big names – there are plenty of promising younger players looking to impress for a global audience.

Kamaldeen Sulemana, 19, winger – Ghana

Hold on to your seats! Kamaldeen is sure to ramp up the excitement at AFCON, such is his rather chaotic approach to attacking – and acrobatic celebration. The teenage winger is immensely tricky and agile, with his 246 take-on attempts in the 2020-21 Danish Superliga nearly twice as many as anyone else – to put that into context, only Lionel Messi managed more (261) in the top five leagues. He's carried that into Ligue 1 following his move to Rennes, with his average of one shot involvements from a ball carry every 43 minutes being the second best in Ligue 1 (min. 900 minutes played) after Kylian Mbappe – that's obviously pretty good.

Ibrahim Sangare, 24, defensive midfielder – Ivory Coast

While good performances at AFCON alone may not be enough for players to convince big clubs they're worth a punt on, showing promise might just get a few more eyes on them. Sangare is definitely one of those who could put himself 'in the shop window'. The PSV midfielder has a lot about him, particularly when it comes to defending. In this season's Eredivisie, only three players (at least 500 minutes played) have averaged more than his 3.4 tackles per 90 minutes, while he ranks fifth for interceptions frequency (2.5) and third for middle-third recoveries (5.7). He's also technically proficient and happy on the ball, with only three players attempting more passes (81.1) on a per-90-minute basis than him.

Hannibal Mejbri, 18, attacking midfielder – Tunisia

A former France youth international, Mejbri may have only declared for Tunisia in 2021 but this will already be his second international tournament. The Manchester United midfielder started all six of Tunisia's games as they reached the final of the Arab Cup in December, eventually losing to Algeria in the final. Hannibal may not feature quite as prominently in a full-strength squad, but the midfielder possesses the kind of off-the-cuff abilities that endear him to fans – if not opponents. He is known to be targeted for fouls when playing for United's second team, such is his natural talent.

Ilaix Moriba, 18, central midfielder – Guinea

2021-22 hasn't quite gone as Moriba presumably thought it would. He left Barcelona after failing to agree a new contract, despite having broken into the first-team setup at Camp Nou. The midfielder had shown exceptional promise, particularly on the ball – he averaged 3.2 dribbles per 90 minutes, a total bettered by only four team-mates, and boasted a success rate of 89.3 per cent, with only Miralem Pjanic bettering him. The €16million signing has played just twice in the Bundesliga since the move to Leipzig and will surely be relishing some competitive action.

Edmond Tapsoba, 22, centre-back – Burkina Faso

If Burkina Faso go on to have a good tournament, Tapsoba will almost certainly have had something to do with it. The centre-back is an extremely elegant player for someone roughly the size of a small building and whose name sounds like a hipster bar, and at club level he performs a vital function in getting Leverkusen on the front foot, with his 13.5 progressive ball carries in the Bundesliga this term second only to Alphonso Davies. If he can translate that to the international stage, Burkina Faso will have a real weapon in the middle – even if he doesn't, he'll still give them aerial threat at set-pieces.

Abdul Fatawu Issahaku, 17, forward – Ghana

The case of Issahaku is a rather intriguing one. Transfer rumours in 2021 suggested Liverpool had signed him for £1.5million, but that soon turned out to be false. He remains in his native Ghana, but the exciting attacker has seemingly done enough to earn a shot at international level despite being just 17 – he's the second-youngest player at the tournament. But he's used to that sort of situation. After all, before he'd even turned 17 in March he was named Player of the Tournament at the Under-20 Africa Cup of Nations. While that Liverpool move never materialised, he's got himself another opportunity to shine.

It's possible that no manager in European football has had a greater transformational effect on a club this century than Diego Simeone has had at Atletico Madrid.

Of course, it's impossible to actually prove/disprove that, but when you consider his eight trophy successes is almost a quarter of all the major silverware the club have ever won, most counterarguments would dissipate.

Yet 2021-22 has been far from smooth, and they could head into Sunday's trip to Villarreal 17 points behind pacesetters Real Madrid, assuming Los Blancos beat Valencia 24 hours earlier.

Part of Atletico's problem is they seem to have lost the defensive solidity that's been a cornerstone of Simeone's tactical plan in his decade at the club.

Sunday's match will be the first since the 10-year anniversary of his bow as Atletico coach on January 7, 2012, providing the opportunity to look at how much of a challenge this season is proving to be.

11 away games, no clean sheet

Nothing is more indicative of Atletico's current malaise than their struggles to shut teams out – they're not getting battered, but we're so used to seeing them boast the shrewdest defence in LaLiga.

That's simply not the case this season.

Their 22 goals conceded is bettered by seven teams and isn't far off being twice as many as Sevilla (13), LaLiga's strongest defence this term.

Atletico's issues have been particularly prominent on the road. They've not secured an away clean sheet in LaLiga in any of their previous 11 such games, which is their worst run since December 2010 (17 matches).

No team has more away clean sheets across the top five leagues than Atletico (85) since Simeone's first match, but Manchester City (82) are closing in, fast.

Missing home comforts

The away struggles alluded to before also translates to defeats, with Atletico losing each of the three most recent matches on their travels.

It's worth remembering that two of those came to Madrid and Sevilla, first and second in the table, but typically Simeone's Atletico are solid enough that such sequences don't occur, regardless of the opposition.

In fact, prior to this run, Atletico had not conceded two or more goals in three successive away league games since January/February 2014.

If they lose to Villarreal, it will be their first streak of four consecutive defeats on the road since December 2011, the month Simeone was appointed.

Yellow Submarine on the rise

It wasn't so long ago that Unai Emery appeared to be in danger of being sacked, then he held talks with Newcastle United but ultimately rejected them.

Some might even suggest that his show of loyalty then bought him a little more time at the Ceramica.

As it turns out, Villarreal staying their hand seems to have worked out well. While they may only be as high as eighth, fourth-placed Atletico are just four points ahead of them.

Their recent run has been crucial to that as well, having won each of their past four league games, the most successive LaLiga victories they've managed under Emery.

The end is Unai?

Atletico can perhaps take confidence from the fact Emery has a dreadful record against Simeone.

He has never beaten the Argentinian in 15 matches across all competitions, the most games Emery has managed against another coach without a win in his entire career.

On the flip side, every record or streak is there to be broken – this particular one surely cannot go on forever, and this is one of the more beatable Atletico teams Emery has faced.

He will hope the end of that particular run is nigh.

Philippe Coutinho and Steven Gerrard are back in tandem, nine years after they first began to forge an alliance at Liverpool.

Gerrard referred to Coutinho as a friend this week, but he is also set to be his boss at Aston Villa after the Brazilian agreed to join from Barcelona.

The theory is that if anyone can get a tune out of Coutinho, it should be his former Liverpool captain, given the strong relationship they had on the pitch, which has endured in the years since.

Barcelona hoped Coutinho would be a leader in their orchestra, but instead his displays often struck a bum note, and the Blaugrana are happy to have offloaded one of the most expensive signings in their history.

Exactly how much they have ended up paying Liverpool for Coutinho is unclear, given the various clauses that were in the January 2018 deal, but he cost the Catalans giants well over £100million, and the return on that investment was far from what was expected.

In LaLiga, he played 76 times, starting 51 games, and managed 17 goals and nine assists. Overall, he had 26 goals and 13 assists in 106 games.

Gerrard will be hoping the 29-year-old Coutinho can sprinkle some magic at Villa, having already shown his qualities in the Premier League.

After a slow start at Liverpool, his performances came on leaps and bounds; across his final two and a half seasons with the Reds, Coutinho managed 38 goals and 24 assists in 99 matches.

In this World Cup year, Coutinho will want to be playing regularly. Such a prospect was off the table at Barcelona, where planning for the long-term future is the order of the day, along with hacking down the wage bill.

Coutinho made an encouraging start at Barcelona, and across all competitions he managed 10 goals and six assists in just 22 games across his first half-season with the Blaugrana.

In 2018-19, he played 54 times and finished with 11 goals and five assists, with his productivity already in decline. From an average of 0.97 goal involvements (goals and assists) per 90 minutes in that honeymoon period after first arriving from Liverpool, his contribution shrank to 0.43 involvements per 90 in his first full season.

In an all-conquering Bayern side, that bounced back up to 0.84 goal involvements per 90 minutes in the 2019-20 campaign, but Coutinho could not crack on at that pace once back at Camp Nou.

Last term, as he made just fitful contributions, his involvements averaged out at 0.57 per 90, and this season's rate was just 0.3 as his inevitable exit approached.

In his final half-season at Anfield, the former Inter winger was contributing 1.2 goal involvements per game as his Reds form peaked.

Across his Reds career, Coutinho scored 19 Premier League goals from outside the penalty area, Opta said. Only Gerrard has scored more for the club from outside the box (33).

Since returning to Barcelona from Bayern, Barcelona have tended to do better when Coutinho has played no part in games.

When he has been involved, either as a starter or substitute, they have won just nine of 24 LaLiga games for a 37.5 per cent success rate, averaging 1.4 points and 1.5 goals.

But without him they have won 23 of 33 (69.7 per cent) in LaLiga, losing only three times, averaging 2.3 points and 2.4 goals per game.

It is little wonder he has played just 26 per cent of minutes across all competitions for Barcelona this season. Injuries have blighted his Barcelona career, and if this is the end, with a loan potentially leading to a sale, then all parties will be happy to move on.

Villa are signing a special player, one that Gerrard still likes to tag as a "magician", but also a footballer who perhaps needs a reminder of those old tricks in his repertoire.

If Gerrard can bring back that spark, that trickery with end results, Villa will be all the better for it.

The 18th and final round of the NFL regular season is upon us and there remains plenty of intrigue in a frantic scramble to make it to the playoffs.

Five teams from the AFC are competing for two postseason berths, while one spot is up for grabs in the NFC. 

Away from the Super Bowl picture, there are a number of other intriguing subplots ahead of an action-packed weekend.

Stats Perform previews some of the standout games and the best of the rest.

Los Angeles Chargers (9-7) @ Las Vegas Raiders (9-7)

The winner of this contest is guaranteed a playoff spot, while there is also a scenario whereby a tie could see both advance. Interestingly, six of the previous seven games in Oakland/Las Vegas have been decided by three points or fewer.

The Raiders beat the Colts on a last-second field goal last week to prevail 23-20 – their fifth win of the season by four points or fewer, tied with the Packers and the Titans for the most in the NFL.

Justin Herbert set the single-season passing touchdowns record for the Chargers last week with his 35th of the campaign. He now requires 172 yards this week to also take the passing-yards record.

The Chargers' 34-13 win against the Broncos was their fourth victory in a win while scoring 30 points or more. They have averaged 33.9 points per game in wins this season, second most in the NFL behind the Bills (35.1).

Pittsburgh Steelers (8-7-1) @ Baltimore Ravens (8-8)

The Steelers have won three in a row against the Ravens, with all three of those victories being decided by less than a touchdown, the most recent coming by a 20-19 scoreline last month.

Last week's 12-point win over the Browns was the Steelers' largest of the season, though not since 1969 have they gone a full campaign without winning by at least 13 points.

The Ravens are coming off the back of a 20-19 loss to the Rams, their league-leading eighth game decided by three or fewer points this season – no team in NFL history has had more than nine games decided by three or fewer points.

Najee Harris rushed for 188 of the Steelers' 190 rushing yards against the Browns and accounts for 77.9 per cent of his side's rush yards this season, the highest share of any player in the NFL.

Kansas City Chiefs (11-5) @ Denver Broncos (7-9)

The Chiefs will be looking to respond to their defeat against the Cincinnati Bengals in week 17 when they take on the Broncos, whom they have defeated in 12 successive meetings – the league's joint-longest active winning streak along with the New England Patriots against the New York Jets.

Despite last week's defeat, the Chiefs have scored at least 30 points in four successive games, which is the longest-running streak in the NFL and one short of their all-time record of five set in 2004 and 2018.

Kansas lead the way in the NFL with 391 first downs this season and, with nine more this weekend, will become the fifth team in the last 70 years with 400 or more first downs in a season.

The Broncos were defeated by the Chargers last time out to ensure a losing season for the fifth straight year, an unwanted run they last went on from 1963 to 1972 with 10 straight losing seasons.

The Jaguars require a victory against the Colts to avoid becoming the fourth team in the last 30 years to have consecutive seasons with two or fewer wins. The Colts have lost three games this season by exactly three points – the Seahawks are the only team this season that has failed to win a single game by three or fewer points with more losses in such games (0-5).

The Rams can clinch their third NFC West title in six seasons season since moving back to Los Angeles with victory over the 49ers. However, the Niners have won each of their last five meetings with the Rams.

The Falcons have three successive wins against the Saints in Atlanta and are seeking a fourth in a row for the first time since between 1991 and 1994. Following defeat to the Bills last week, the Falcons have alternated between wins and losses over their last seven games.

The Bills can clinch their second consecutive division title with victory against the Jets, following on from a previous run of 24 straight seasons without finishing top. All 10 of Buffalo's wins this season have come by 12 points or more.

Premier League managers are already feeling the strain amid cascading numbers of COVID-19 cases and mid-season injuries. Now many top bosses stand to lose stars to the Africa Cup of Nations.

Africa's greatest football show – now commonly known as AFCON – gets under way on Sunday in Cameroon.

Although the 2019 edition was held in June and July, it has historically been a January-into-February tournament and has returned to that place on the calendar.

A host of Premier League big names are hoping to make an impact during the four-week tournament, which falls slap-bang in the middle of European club campaigns, causing a major clash of competitions.

Premier League clubs certainly cannot complain of a lack of fair warning. It was June 2020 when African football chiefs decided the 2021 edition of the tournament would have to be pushed back by 12 months to a January 2022 start, in the hope the coronavirus crisis would have eased.

Here, Stats Perform takes a look at which teams from the English top flight might feel its impact the most.

Can Reds cling on in title battle?

If Liverpool lose no further ground on leaders Manchester City by the time their stars return from AFCON, then Jurgen Klopp would surely settle for that.

The 2019-20 Premier League champions have taken two points from a possible nine to leave the title as effectively City's to lose, and now Klopp is going to have to get by without Mohamed Salah, Sadio Mane and Naby Keita.

Egyptian striker Salah is the Premier League's leader in goals (16) and assists (9, level with Trent Alexander Arnold) so far this season. He has taken 80 shots in 20 games (38 of these have hit the target), played 12 throughballs and created 40 chances from open play: in each of those categories he is at the top of the Premier League charts for players defined by Opta as forwards.

How do you cope without such a contribution? Having Mane on hand would help, but Mane will be turning out for Senegal, a team who, like Salah's Egypt, are firmly in the mix as serious trophy contenders. Don't expect either back at the end of the group stage.

Mane has eight Premier League goals this term, including the opener at Chelsea recently. That goal return puts Mane joint-second among African scorers in the Premier League this season, level with Watford's Emmanuel Dennis, who is not in Nigeria's squad.

Mane has played 19 throughballs and has made 23 tackles to boot, which is the seventh highest number of tackles by a forward in the league this season, a rarely mentioned attribute of his game. He does not always tackle with his elbow, either.

Keita will presumably be less of a miss, with the Guinean's Anfield contribution remaining underwhelming, but Liverpool have been so hard hit by absentees recently that to lose anybody for up to five weeks is an inconvenience.

They are at least assured of Joel Matip's presence this month. The centre-back last played for Cameroon in 2015 and has retired from international duty. That is bad news for the AFCON hosts but helps Liverpool, given Matip remains a sturdy presence, with a duel success of 69.47 per cent this season ranking him third among Premier League defenders with 10 or more appearances, and a passing accuracy of 88.89 per cent putting him eighth in that metric.

Liverpool only have two league games inked in between now and the end of AFCON, against Brentford and Crystal Palace, but the Reds also have two postponed fixtures to be slipped in somewhere along the line.

Wintertime Blues?

Pep Guardiola's Manchester City hold a 10-point lead over second-placed Chelsea, with Liverpool a point further back but possessing a game in hand on the top two. Reigning champions City have won 11 straight Premier League games and the Citizens have the resources to be able to cope with the short-term loss of Riyad Mahrez, who will captain Algeria.

Mahrez's six goals and four assists this season have come at a startling rate. Given the depth in City's squad, he does not always start, so to appreciate his contribution it is worth looking at his numbers per 90 minutes on the pitch.

The former Leicester City forward is averaging 0.64 goals and 0.43 assists per 90 minutes – impressively close to Salah's return of 0.81 and 0.45 in those categories – and is one of only four Premier League players with 10 or more appearances to average at least 1.00 goal involvements per 90 (Michael Olise 1.43, Salah 1.26, Roberto Firmino 1.24, Mahrez 1.07).

The Blues of Chelsea may have concerns over the absence of goalkeeper Edouard Mendy, given the Senegalese's stabilising influence at the back. His save percentage of 77.14 has only been beaten this season in the league by Wolves' Jose Sa (80.82) and Arsenal's Aaron Ramsdale (77.46).

Spaniard Kepa Arrizabalaga struggled in the early stages of his Chelsea career and is now the undoubted understudy.

Yet Kepa's form when given an opportunity this season has not given such cause for concern. The former Athletic Bilbao goalkeeper has been chiefly used in cup action, and he has achieved a remarkable save percentage of 81.48, suggesting that for a short run of games, he could be a perfectly able deputy.

Can an exodus to Africa affect the race for Europe?

Will fourth-placed Arsenal miss Pierre-Emerick Aubameyang? It seems unlikely now, given he was dropped and stripped of the captaincy after a disciplinary breach before heading off to join Gabon. He has not played for a month. The Gunners won five games in a row without him, including four in the league, before being unlucky to lose to Manchester City.

Cold facts tell us Arsenal have a points average of 1.9 per Premier League game when Aubameyang has started games this season, and 1.5 when he has been either a substitute or out of the team, but those figures may not be significant given the momentum Mikel Arteta's players have built in the recent absence of the 32-year-old. His continuing exile from the first team seems unlikely to cause much consternation.

For manager Arteta to lose Thomas Partey (Ghana) at this point is a blow though, with the former Atletico Madrid player having been excellent in the 2-1 defeat to City, having been slowly building up to such a performance. He had more touches, won more duels, made more tackles and played more successful passes than any other Arsenal player.

Arsenal have a big derby at Tottenham coming up on January 16, and they might feel Partey's absence that day, particularly given Spurs, who currently sit sixth, are sending no current first-teamers away to AFCON.

Splitting the north London rivals for now are West Ham, in fifth, and it will surely have hurt David Moyes to wave off Said Benrahma for a month of Algeria duty. The playmaker has five goals and four assists in the league this season, as well as making 83 ball recoveries and creating 21 chances in open play. That makes him one of only 13 players in the competition to top both 80 recoveries and 20 open-play chances created, and one of only five Premier League stars to tick both boxes and score at least five times. Crystal Palace's Wilfried Zaha, away with Ivory Coast, is another member of that small group.

Seventh-placed Manchester United will lose Eric Bailly to Ivory Coast too. But with Phil Jones back in the first team, will Bailly be missed? The former Villarreal centre-back has played just 217 minutes in the Premier League this season. United youth prospect Hannibal Mejbri is also away, in his case with Tunisia.

Further into mid-table, Wolves must find an alternative to the excellent Romain Saiss (tackle success rate 72.73 per cent) on the left side of their defence, after he joined up with Morocco. Brighton and Hove Albion powerhouse Yves Bissouma has the highest tackle success rate among midfielders to have made more than 40 such challenges in the Premier League this season (50 attempted, 35 won: 70 per cent hit rate) and he will line up for Mali after ending an international exile.

Leicester City sent away striker Kelechi Iheanacho (2 goals, 4 assists this season) for Nigeria service at a bad time for the Foxes, given injured Jamie Vardy faces several weeks out of action.

Palace are firmly in favour of players heading away to represent their countries, but the Eagles never particularly like to be without Zaha (5 goals, 1 assist, 86 dribbles). Since his return from Manchester United in August 2014, Palace have averaged 1.2 points and a 32.9 per cent win percentage with Zaha in their starting line-up, and 0.9 points and a 24.5 win percentage when he has not been in that matchday XI. The loss of Cheikhou Kouyate (80.56 per cent success rate from 36 tackles) to Senegal duty may also diminish the sturdiness of Patrick Vieira's Eagles spine.

Can Clarets cope without Cornet?

The relegation scrap seems more likely to be affected by transfer market activity than departures to AFCON.

Newcastle United and Norwich City, the league's bottom two, are sending nobody away, while fourth-bottom Watford have kept Dennis (8 goals, 5 assists) and it remains to be seen what happens to Ismaila Sarr (5 goals), who has been absent with injury of late but has headed for checks with Senegal doctors.

Burnley, who sit 18th, are seemingly the team to watch carefully here. Maxwel Cornet, now away with Ivory Coast, has scored six Premier League goals from just 10 shots on target, and Sean Dyche must find a way to make the Clarets impactful without the former Lyon man.

If Thomas Tuchel is after any advice on how to deal with the Romelu Lukaku issue, the Chelsea head coach could do worse than to have a brief word with the man he will come face-to-face with on Wednesday.

Under now-Tottenham boss Antonio Conte across two seasons with Inter, Lukaku enjoyed the best form of his career, scoring and assisting a combined 81 goals in 95 appearances.

Lukaku has not been as prolific since returning to Stamford Bridge in August, finding the net seven times in 18 games, and already his future at Chelsea has been called into question following an explosive interview in the Italian press that was published last week.

The Belgium international was subsequently dropped for Chelsea's crucial clash with Liverpool on Sunday but is in line return for the EFL Cup semi-final first leg with Spurs after holding clear-the-air talks with his manager, meaning a possible reunion with Conte.

Here, Stats Perform looks at how Conte got Lukaku out of the "deep hole" he found himself in at Manchester United, as the striker himself put it, and explores how Tuchel can go about getting the most out of Chelsea's all-time record purchase.

ROM AMONG EUROPE'S ELITE

As well as declaring an unhappiness with his role at Chelsea and expressing a desire to return to Inter as part of his 30-minute chat with Sky Sport Italia, Lukaku also opened up on the "hurt" he felt when Conte departed San Siro.

That is no surprise given the Belgian's form between arriving at Inter in August 2019 and departing two years later. 

The 47 Serie A goals scored by Lukaku in 72 games under Conte is his best return under any of the 11 managers he has played for at club level, followed by the 43 netted in 103 Premier League games when working with now-national team coach Roberto Martinez at Everton.

That includes a return of 24 goals in 2020-21 alone, on top of 11 assists, as he became the first player to score 20-plus goals and set up 10 or more in a single Serie A season since Opta started to record such data in 2004-05.

Indeed, only Cristiano Ronaldo (83), Kylian Mbappe (97), Lionel Messi (106) and Robert Lewandowski (121) were directly involved in more goals in all competitions among players from Europe's top five leagues than Lukaku's 81 across the 2019-20 and 2020-21 seasons.

FLOPPED IN FAVOURED FORMATION

That impressive form helped Inter end their 11-year wait for Scudetto success last time out, a year on from falling just short in the Europa League with defeat in the final, but Lukaku was not alone in inspiring the Nerazzurri to glory.

Alongside him was Lautaro Martinez, who was very much the perfect foil in Conte's preferred 3-5-2 formation, which the Italian used 31 times in 38 league matches last season.

It is a formation Tuchel has used on only two occasions in the Premier League this term – in September's 1-0 home defeat to Manchester City and the 1-0 victory at Brentford three weeks later. 

Lukaku started both games alongside Timo Werner and Chelsea's tally of five shots against City and five against Brentford are the fewest the Blues have managed in any league game this term – Lukaku responsible for just one of those – as were the four and two chances created respectively.

While City's quality and dominance of the ball must be factored in, Lukaku's minimal involvement against Brentford was surprising – and surely no coincidence.

That west London derby blank came in the midst of a 10-game run without a goal for Lukaku, not helped by niggling injuries and a COVID lay-off, which he has since put an end to with three goals in four matches.

Chelsea's formation in those three most recent games Lukaku has scored in, incidentally, came with three attackers spread across the frontline. And there was one other common denominator, too: Mason Mount being on the field.

MOUNT TO PLAY THE MARTINEZ ROLE?

Mount assisted Lukaku's most recent goal in a 1-1 draw against Brighton and Hove Albion from a corner and the pair have combined to create nine chances in total for one another in the league this term, making it easily Chelsea's most dangerous partnership.

No Chelsea player has combined more regularly with Lukaku than Mount, with the pair linking up 10.06 times per 90 minutes so far this season. While that may not appear a huge amount on the face of it, next on that list is Mateo Kovacic with 6.45 combined passes between himself and Lukaku per 90.

However, Mount still has some way to go if he is to match the 54 combined chances created for each other in Serie A by Lukaku and Martinez in their two seasons used in tandem at Inter, which equated to nine assists.

Lukaku's relationship with Mount does provide some promise, though, as does the Anderlecht academy product's goalscoring performances in his most recent two outings prior to being dropped against Liverpool, showing Chelsea do not necessarily have to replicate Inter's system to help their main man thrive.

TUCHEL WILL NOT SHIFT

Lukaku is averaging fewer passes, overall touches and touches in the opposition box this season compared to last, while also shooting less frequently, dribbling less and creating fewer chances for others.

Yet instead of attempting to find the perfect formula and personnel for Lukaku, Tuchel will not shift from his own way of thinking.

"We cannot just play like Inter in the hope that will bring the most out of Lukaku. The system they played not only suited Romelu but also Lautaro Martinez and others. If you don't have five players you can't play five defenders," Tuchel said on the eve of the Tottenham tie.

"It works both ways. It is more about principles of how we play. I feel he is more impatient than anything else. He wants to be involved more, wants more big chances. 

"Like with every transfer, you have to accept there is a change of environment, culture, team-mates, playing style, belief. He's not the first player to take time, but even while doing it he was scoring goals."

And maybe Tuchel has a point. After all, for all the talk of Lukaku's struggles and unhappiness, he is scoring at an almost identical rate to Cristiano Ronaldo (0.54 goals per 90 minutes compared to 0.56), and remains one of Europe's most prolific strikers of the past decade.

Now back from injury and a team exile brought on by his own actions, only Lukaku can ensure he avoids falling down another deep hole that he may this time be unable to escape.

The first heavyweight tussle of the new year in the Premier League did not disappoint as Chelsea and Liverpool played out an entertaining 2-2 draw at Stamford Bridge.

The Blues were held at home for the fifth time in six league games, a run that includes three straight draws in the top flight for the first time since February 2016.

But Thomas Tuchel's side can be happy with a point after recovering from two goals down as they extended their unbeaten run against the Reds in the league to four matches.

While there was nothing to separate the sides sitting second and third, Brentford, Brighton and Hove Albion and Leeds United were all victorious on Sunday.

Here, Stats Perform unpacks the pick of the Opta data from another eventful day in the Premier League.

Sadio Mane opened the scoring in a Premier League game for the 37th time since joining Liverpool in 2016-17 – only Tottenham's Harry Kane (40) has done so on more occasions.

However, some will argue that Mane was fortunate to be on the field at that point after catching Cesar Azpilicueta with his elbow after just six seconds.

Mane was instead issued a yellow card with 15 seconds on the clock, making it the earliest booking in a Premier League game since Opta started recording such data in 2006-07, nine seconds faster than the previous quickest caution for Scott McTominay against Newcastle United in December 2019.

Mohamed Salah went on to double Liverpool's lead with his fourth league goal against Chelsea, which is the joint-most any player has scored against the Blues after playing for them, along with Manchester City's Kevin De Bruyne.

Chelsea responded brilliantly with two goals in the space of 245 seconds through a Mateo Kovacic stunner and Christian Pulisic's well-taken strike, ensuring they remain a point above their opponents having played a game more.

This was the fourth occasion in this season's Premier League that a side has failed to win a game in which they have led by two goals, with Liverpool accounting for two of those occasions, having also drawn 2-2 with Brighton in October.

Leeds United 3-1 Burnley: More Maxwell magic not enough

Leeds scored three times in a Premier League game for the first time this season on their way to ending a four-game run without a victory, putting distance between themselves and Burnley in the final relegation spot.

Previously with just one win to their name in the competition since the end of October, Jack Harrison squeezed home for Leeds to open the scoring at Elland Road before Maxwell Cornet equalised through Burnley's first direct free-kick goal since Boxing Day 2017.

That was Cornet's sixth Premier League goal in 10 appearances, the most by an African player in their first 10 games since Pierre-Emerick Aubameyang for Arsenal in April 2018 (also six).

Stuart Dallas restored Leeds' advantage on his 250th appearance for the club in all competitions, becoming the first United player to reach that tally since Lucas Radebe in November 2003.

The much-needed victory was sealed by Daniel James in added time, meaning Leeds are unbeaten in 10 Premier League games against sides starting the day in the relegation zone (W8, D2) since returning to the top flight last season.

As for Burnley, they have now won just one of their last 20 Premier League matches and are winless in 11 on their travels, their worst such run on the road since 17 without a victory between August 2016 and April 2017.

Everton 2-3 Brighton and Hove Albion: Mac Allister inspires soaring Seagulls

The highest-scoring game of the day in the Premier League took place at Goodison Park, where Everton suffered defeat in their opening league game of a calendar year for the fifth year running, their worst such streak since a run of seven between 1957 and 1963.

Brighton's opening goal via Alexis Mac Allister after two minutes and 43 seconds was the Seagulls' fastest-ever away from home in the competition, and their third-fastest overall.

Dan Burn doubled the visitors' lead on Merseyside, shortly before the returning Dominic Calvert-Lewin became the 22nd different player to miss a Premier League penalty for the Toffees – only Arsenal (23) have more.

Anthony Gordon scored his first senior goal to give Everton a bit of hope, only for Mac Allister to register for a second time as Brighton moved to 27 points after 19 games – their joint-best return at this stage of a top-flight campaign alongside 1981-82.

It was another afternoon to forget for Rafael Benitez, however, with Everton having now picked up only 19 points from 18 games, which is their worst return at this stage since accruing 17 from 18 matches in 2005-06.

Brentford 2-1 Aston Villa: Bees bounce back again

Comeback experts Brentford hit back to beat Villa late on thanks to goals from Yoane Wissa and Mads Roerslev after Danny Ings had opened the scoring in west London.

Only West Ham (12) and Everton (11) have won more points from losing positions in the Premier League this term than Brentford, who have now recovered nine points in total.

That is in complete contrast to a Villa side that have lost more games in the competition since the start of last season after scoring first than any other side (eight).

Ings has now opened the scoring in more different English top-flight games since the start of 2019-20 than any player (18), but that early strike was not enough for Steven Gerrard's men.

Wissa's equaliser was Brentford's first Premier League goal from outside the box and full-back Roerslev, who set up that strike, completed the turnaround to become the second Bees player to score and assist in the same game in the competition for the club after Ivan Toney.

It was a breathless game at Stamford Bridge on Sunday as Chelsea and Liverpool played out an entertaining 2-2 draw that saw Manchester City emerge as the biggest winners.

An exciting encounter that many will say was a great advert for the Premier League was in reality more an example of why there is unlikely to be any excitement in this year's title race.

Both teams showed immense quality at times, especially in scoring their goals, but also evidenced numerous weaknesses that simply do not exist at City, or at least not to the same extent, though it must be said that both were missing key players through suspension, injury and/or COVID-19 – or were just dropped for talking too much.

The headlines were already being written as the visitors took a 2-0 lead in the first half, with the Blues' star striker Romelu Lukaku missing from the squad after recent comments that displeased his manager Thomas Tuchel.

But Chelsea came back to level up before half-time without the Belgium international to prove that perhaps they are actually better off without him.

It is something that bears exploring more broadly across the game. Is the impact of number nine's slightly overrated? Tottenham have been unable to win a trophy despite having Harry Kane in their ranks, while Borussia Dortmund seldom look like troubling Bayern Munich even though they have the much sought after Erling Haaland to call on.

Also, for all the talk about how desperately they needed a superstar striker in the summer after Sergio Aguero left, City sit ten points clear at the top of the table with only Gabriel Jesus as a recognised number nine in their ranks, and he rarely plays there himself these days anyway.

Kai Havertz played the role of striker for Chelsea here, as he did for much of last season when they won the Champions League, and though he did not have much impact himself, Tuchel's fluid formation seemed to enable Mateo Kovacic and N'Golo Kante to dominate on the ball from deep in a way they sometimes struggle to when Lukaku is leading the line.

Chelsea have played 13 league games with Lukaku this season and eight without. While their win percentage is better with him (61.5) than without (50), they score 2.5 goals per game when he is not there compared to 1.9 when he is.

Despite two goals going in against Liverpool, they still only concede 0.5 goals per game on average when Lukaku does not feature, and 0.9 per game when he does.

When the former Everton and Manchester United striker said that Tuchel does not play in a way that suits him, it is almost certainly correct given how the team overall appears to function better without the striker, but also calls into question why Chelsea decided to spend close to nine figures on him in the first place.

As for Liverpool, boss Jurgen Klopp will have been watching from home after testing positive for COVID-19 satisfied with the score after 26 minutes, but concerned to see that once again, his men were unable to hold onto a lead.

It was the fifth time in the league this season that the Reds have dropped points from a winning position (also against Brentford, Manchester City, Brighton and Hove Albion and Tottenham) and it almost certainly extinguished any faint hopes they will have had of pegging City back in the title race, now sitting 11 points behind with a solitary game in hand.

Liverpool allowed 15 shots at their goal, with Irish stopper Caoimhin Kelleher making some excellent saves to keep his team in it after stepping in for Alisson Becker (COVID-19), and although Chelsea's goals from Mateo Kovacic and Christian Pulisic were expertly taken, they felt like they had been coming such was the visitors' inability to put their foot on the ball and calm things down.

This was something that set them apart when they ran away with the Premier League title in 2019-20, their penchant for killing a game off once they went ahead. They missed the influence of the injured Thiago Alcantara in the midfield, and arguably still have a bit of a Georginio Wijnaldum-shaped hole after the ever-reliable Dutchman left for Paris Saint-Germain at the end of last season.

Up top, they were looking as good as ever, with early goals from Sadio Mane and Mohamed Salah seemingly putting them in control. Mane did well to round Edouard Mendy and fire home seconds after Mason Mount had failed to do the same at the other end, while Salah was sumptuous as he dribbled past Marcos Alonso and caressed the ball in at Mendy's near post to make it two.

Klopp will undoubtedly miss the dynamic duo as they now head off to the Africa Cup of Nations, with Salah in particular in the form of his life, getting his 16th league goal of the campaign and his 150th in all competitions in English football.

Mane actually ended a dry spell here, having gone nine games without a goal in all competitions. Senegal will be pleased at least that he seemed to have his spark back at Stamford Bridge, but with back-ups Takumi Minamino and Divock Origi currently injured and Roberto Firmino out with COVID-19, Klopp will perhaps have to get quite creative to fill the huge void Mane and Salah will leave for the next few weeks.

Both managers have selection headaches on the horizon, but after another weekend in which everything possible went the way of Pep Guardiola, the likelihood is that those selection headaches will only be in an effort to ultimately clinch second spot in this year's Premier League.

Manchester City picked up from where they left off in 2021 by battling to a late 2-1 win over Arsenal, extending their lead at the Premier League summit.

A Riyad Mahrez penalty and a last-gasp strike from Rodri cancelled out Bukayo Saka's first-half opener after Gabriel Magalhaes received a needless red card for the Gunners in an action-packed game – the first top-flight match of 2022.

City's 11th league win in a row means they end New Year's Day with an 11-point advantage at the top, a tally bettered by only two clubs in the competition's history on January 1 – Manchester United in 1993-94 and City themselves in 2017-18 (both 12 points).

There were also victories for Tottenham and West Ham, the London pair seeing off Watford and Crystal Palace respectively to remain in firm contention for a top-four finish.

Here, Stats Perform unpacks the pick of Opta data from Saturday's action. 

Saka's opening goal against City was only the second the Citizens have conceded in the first half of a Premier League game this season, and the first such goal they have shipped on their travels since May.

That was the England international's sixth league goal of the season and was the 36th goal scored by a player aged 21 or under for Arsenal in the English top flight since Mikel Arteta's first game on Boxing Day 2019 – eight more than any other team.

Mahrez converted a contentiously awarded penalty shortly before the hour mark at Emirates Stadium, the Algeria international scoring for a fifth game running in all competitions, and Gabriel's second yellow card – 78 seconds after his first – swung the game in City's favour.

That was Arsenal's 100th red card in the Premier League era, making them the first side to reach that milestone, with Everton (99), Newcastle United (90) and Chelsea (82) next on the list.

Rodri completed the turnaround with City's latest winning goal in a league game since May 2018 (92:28) as the Citizens made it 10 successive top-flight victories over the Gunners, an opponent Pep Guardiola has yet to lose against in the league in 12 encounters.

Watford 0-1 Tottenham: Sanchez stings Hornets in late Spurs win

Tottenham also left it late to overcome Watford and make it eight Premier League games without defeat under Antonio Conte, extending the longest unbeaten start by a Spurs boss in league competition.

Davinson Sanchez made the breakthrough with 95 minutes and 45 seconds played, with that the latest winning goal Spurs have scored in the top flight since Opta started recording such data from 2006-07.

Watford dug deep but could not quite hold on for a valuable point, meaning they have now lost more Premier League matches (nine) since Claudio Ranieri took charge in October than any other side in the division.

Sanchez's goal was his second in five Premier League matches for Spurs, which is more than he had netted in his first 108 in the competition (one), with the defender heading in from a Son Heung-min free-kick.

Watford boss Ranieri has now lost each of his last five Premier League games against Italian managers, whereas compatriot Conte has never lost against a fellow Italian in the competition in six meetings, winning all but one of those.

Crystal Palace 2-3 West Ham: Hammers survive Olise-inspired scare

Palace fell just short of pulling off a remarkable comeback as they lost a home league match on New Year's Day for the first time in their history, with this their 14th such match.

Michail Antonio's close-range finish and a Manuel Lanzini double gave West Ham a commanding three-goal lead, the latter having now scored 52 per cent of his 25 Premier League goals in London derbies (13) – the highest percentage of any player to have scored at least 20 times in the competition.

Michael Olise made a huge difference from the bench by setting up Odsonne Edouard and then scoring a second for Palace late on, making him the first Eagles player to score and assist as a substitute in the Premier League.

But the visitors held on to ensure boss David Moyes made it six straight away league wins against Palace as a manager, defeating a different coach on each occasion during that perfect run (Alan Smith, Iain Dowie, Tony Pulis, Sam Allardyce, Roy Hodgson and now Patrick Vieira).

Moreso than any other team in the NBA, the Cleveland Cavaliers have lived at opposite ends of the league over the last two decades. 

Since 2002-03, Cleveland has finished with 25 or fewer wins in seven different seasons, tied with the Minnesota Timberwolves for the most in basketball.

But those seven dreadful seasons have also yielded some generational talents in the NBA Draft, most notably LeBron James and Kyrie Irving, leading to eight seasons with 50 or more wins over that span, the most in the Eastern Conference and the fourth most in the NBA. 

In the three full campaigns since James left Cleveland for the second time, the Cavs have gone an NBA-worst 60-159, but fans in Ohio are hopeful that this season's 20-15 start is evidence that those lean years have produced enough talent to fuel a franchise turnaround yet again.

Last season the Cavs accrued 34 losses before earning their 20th win, but their improvement runs even deeper. 

Cleveland has improved in almost every significant statistical category, but the growth on defense has been dramatic. Last year's squad had one of the league's five worst defenses, allowing 112.1 points per 100 possessions. This year, the Cavaliers are allowing 102.2 points per 100 possessions, the third-best mark in the league and the top in the East.

When combined with an offense that has shown incremental improvement, the Cavaliers have a net rating of +5.2 per 100 possessions, the fourth best in the NBA and ahead of fellow Eastern contenders like the Brooklyn Nets, Miami Heat and reigning champion Milwaukee Bucks.

All of this has come with Cleveland facing the NBA's third-toughest schedule so far, with an average opponents' win percentage of .526. 

While some predicted that the Cavs' hot start would fizzle out into another losing season, the team has maintained its wining ways through nearly half the season and looks to be in position to continue.

Despite playing in a division with the Bucks and surprisingly good Chicago Bulls, Cleveland's remaining schedule is the easiest in the NBA by opponents’ average win percentage, with a majority of the upcoming being played at home.

Rookie Evan Mobley, selected with the third overall pick in July's draft, has been the catalyst for Cleveland's transformation this season. The 20-year-old big man is fourth in rookie scoring at 14.3 points per game but has made an all-around impact more typical of a veteran than a player who was in high school two years ago.

The Cavs' selection of the seven-footer Mobley was criticized by some pundits as redundant after the franchise had just re-signed center Jarrett Allen to a contract worth $100million earlier last offseason. 

Mobley and Allen have answered critics by forging one of the most formidable frontcourt defenses in the NBA. When Mobley and Allen are on the court together, the Cavaliers have a preposterous 95.3 defensive rating and opponents are shooting just 40.7 percent from the floor.

In a league that continues to downsize, Mobley has started most of his games at power forward, but the Cavs have found they do not sacrifice much offensively because their young star is so skilled and versatile.

While Allen has thrived around the rim this season, Mobley has the skill and athleticism to play everywhere, spacing the floor and keeping the ball moving on offense while smothering all sizes of players on defense.

Credit is due to head coach J.B. Bickerstaff, who identified early on that his frontcourt players were talented enough that he could buck the league's small-ball trend by starting his twin towers lineup.

Bickerstaff also had the courage to tell Kevin Love, the team's highest-paid player, that he would be coming off the bench. Love, who has been openly disgruntled about Cleveland's losing records in previous years, has embraced his new role and has seen a resurgence in both enthusiasm and efficiency.

The Cavaliers have been so pleased with Bickerstaff's leadership, in fact, that the parties agreed to a multiyear extension last week that keeps him under contract through the 2026-27 season.

Bickerstaff, Mobley and Allen – who is still just 23 years old – form a foundation that Cleveland intends to build upon for the next several years.

The Cavs' other unquestioned franchise staple is point guard Darius Garland, who has continued to improve in his third year. Garland is on pace for career-highs with 19.5 points per game, 7.3 assists per game and 47.9-percent shooting from the field. 

Garland has been forced to shoulder a heavy offensive burden and will be an even more vital player as the Cavs entered the second half of the season.

Backcourt mate and last year's leading scorer Collin Sexton was lost for the season after tearing cartilage in his left knee on Nov. 7.

Sexton's injury forced veteran guard Ricky Rubio into a more prominent role, a combination that worked very well for several weeks until Rubio suffered a torn anterior cruciate ligament in his left knee on Tuesday, ending his season as well.

The thinning of their backcourt led to the Cavs trading for the 16th-year veteran as an experienced floor general just before the calendar flipped to 2022.

It looks as if the 2021-22 season will be one of attrition, and a lack of depth may ultimately prevent the Cavaliers from maintaining an elite point differential in the East. But with a team so young, the franchise would have to be pleased just to play in the postseason again.

Going forward, however, Cleveland faces a crossroads decision in the coming offseason with Sexton's contract. The fourth-year guard is in the final year of his rookie deal, and the front office must decide if the Garland-Sexton backcourt combination is the best long-term option.

Sexton averaged 24.3 points per game last season, making it seem like offering him an extension would be the obvious solution. But high-scoring numbers like that typically demand a maximum contract – in this case, $173million over five years.

Garland and Sexton both stand just 6ft1, creating some flexibility issues. Since the latter was drafted in 2018, the Cavaliers have been wiling to live with a defensive liability in the backcourt as they focused on collecting talent and developing young players.

But now that Cleveland appears ready to make a run at the playoffs, more serious questions must be answered.

During Sexton's four-season tenure, the Cavs have allowed a staggering 115.5 points per 100 possessions while he is on the court versus 107.2 when he sits.

And despite Sexton's impressive scoring numbers, Cleveland's offensive numbers while he his on and off the court are virtually identical – over a sample size of over 12,000 minutes.

Paying Sexton long-term could lock in a future where the Cavs have the league's smallest backcourt and largest frontcourt, making them vulnerable to perimeter shot creators with size, the kind that has proven to be invaluable in postseason play.

All of that said, any team would be foolish to surrender a talented scorer like Sexton for nothing. A small-market team like Cleveland would be outright negligent. He is likely to get his extension, especially with the entire core being so young.

Garland, Sexton, Mobley and Allen have played less than 120 minutes on the floor together, and Cleveland's brass is likely to want to see them grow a bit more together.

Plus, teams in markets that are not free agency destinations simply do not have the luxury of being so choosy about trying to construct the ideal roster.

Although this Cavs team has some quirks that might project into a playoff ceiling in the future, Cleveland's front office has organically built a fun team – and one that appears to be a winner.

That is something the Cavs haven't done without LeBron James since last century.
