Robert Lewandowski hit a hat-trick as Bayern Munich set a Bundesliga record in Saturday's 4-0 away win over Cologne.

The Poland striker's ninth-minute opener meant the champions scored in a record 66 consecutive league games, a feat never before achieved in Germany's top tier.

Corentin Tolisso scored a fine second before two more Lewandowski goals in the second half secured a ninth league win in a row over Steffen Baumgart's side.

Fittingly, it was Lewandowski who set Bayern's latest goalscoring record, the striker side-footing past Marvin Schwabe from Thomas Muller's pass and a VAR check overruling the offside call.

The visitors doubled their lead in spectacular fashion, Tolisso controlling Muller's lay-off before rifling left-footed into the top-right corner from the edge of the box.

Cologne thought they had pulled a goal back through Mark Uth, but another VAR check showed an offside, and the hosts finished the half without another shot on target.

Marcel Sabitzer had an effort saved and Jamal Musiala's turn and shot clipped the outside of the post as Bayern stepped up their pressure after the interval.

Cologne offered a slight threat of a comeback with a good period of pressure, but it was promptly Lewandowski quelled 62 minutes in, Lewandowski drilling home his 22nd Bundesliga goal of the season after being played through by Leroy Sane.

The pair combined again for Bayern's fourth, Muller releasing Sane on a zig-zagging run before he prodded through for Lewandowski to finish with aplomb.

What does it mean? Bayern respond to Dortmund pressure

You have to go back to February 9, 2020, and a goalless draw with RB Leipzig, to find the last occasion in which Bayern played a league game without scoring a goal.

Their latest two helped them to a comfortable win that stretched their lead at the top back to six points, Borussia Dortmund having closed the gap with a 5-1 thumping of Freiburg on Friday.

Cologne sit eighth in the table, but just two points off the top four.

Magnificent Muller

Lewandowski's goalscoring exploits can often overshadow Muller, but two assists and four chances created here were a reminder of his importance to Bayern.

The Germany star has now directly set up 150 Bundesliga goals since his debut back in August 2008. In that time, only Lionel Messi (180) has made more assists in Europe's top five leagues.

No sniff of a Cologne goal

Cologne managed only one shot on target throughout and starting strikers Uth and Anthony Modeste were substituted even before Lewandowski netted Bayern's fourth.

They had promising moments in the final third but this was a surprisingly toothless performance from a side whose 28 points from their first 18 games was their second-best return this century.

What's next?

Bayern are back in action next Sunday away to Hertha Berlin. Cologne host Hamburg in the DFB-Pokal on Tuesday before resuming league duties at Bochum four days later.

Thomas Tuchel was unimpressed by the performance of Romelu Lukaku after Chelsea lost 1-0 to Manchester City at the Etihad Stadium.

A stunning goal from Kevin De Bruyne sent Pep Guardiola's City 13 points clear of Chelsea in the Premier League table, with the Blues having won just four of their last 12 league games.

Lukaku cut a lone figure for much of Saturday's game, having just 21 touches – the fewest of any starting player for either team – while completing just seven out of 12 passes, and he did not win any of his seven aerial duels.

He also saw a shot saved by City goalkeeper Ederson when through one-on-one at the start of the second half, a chance that Opta measured with an xG (expected goals) score of 0.365, meaning that he would be expected to score at least one in three times from that position.

The £97million signing from Inter recently apologised to the club and the fans after giving an interview in Italy where he appeared to criticise Blues boss Tuchel for not playing to his strengths.

Speaking to BT Sport after the game, Tuchel explained his frustration with the Belgian striker's display, saying: "He had many ball losses without any pressure, many ball losses in very promising circumstances. He had a huge chance.

"We want to serve him, but he is part of the team, and the performance up front, particularly in the first half, we can do much, much better."

Apart from Lukaku, Tuchel was reluctant to fault his team at the post-match news conference despite the defeat, and praised their attitude and commitment in the game, saying to reporters: "I think we lost on individual performance and on one situation today. In terms of attitude, commitment, defensive-wise, I am happy.

"We did not allow too many big chances, kept them to a minimum, and we were aware and active with our defending.

"We had big counter chances, big offensive transition chances we wasted. With the same performance we have won games against Man City, and we could draw this game, and, of course, lose this."

Chelsea managed just four shots and one on target, all of which came in the second half, and Tuchel acknowledged that the European champions did not create enough, only having seven touches in the City box compared to the hosts who had 31 in the Chelsea penalty area.

"We did not have enough chances for the ball wins and the movements we could have had," Tuchel added. "We could have had more chances if we played with better timing, better precision. It's simply like this.

"We had eight or nine transition chances and out of them we did not have a touch in the box. This is what I am critical about. If we miss chances, I am not critical. Everyone wants to score big chances, and we do not get a lot of them in big games.

"We could have had many more chances, that is what I am critical about. The decision-making and timing wasn't at the level we need."

Tuchel was also asked for his reaction to the Premier League's decision to postpone Sunday's north London derby between Arsenal and Tottenham after the Gunners made a request on Friday, due to having a number of players out through injury, suspension, COVID-19 or at the Africa Cup of Nations.

The former Borussia Dortmund manager has recently expressed frustration with the league for postponing some games and not others, including rejecting Chelsea's request to cancel their visit to Wolves in December.

"It's much better for me not to answer the question. Much, much better," the German said.

Pep Guardiola was overjoyed with the match-winning performance of Kevin De Bruyne in Manchester City's 1-0 defeat of Chelsea but is convinced the Belgian has even more to offer.

De Bruyne got City's decisive goal in the second half on Saturday, curling a sumptuous effort past Kepa Arrizabalaga from 25 yards out.

It was his fifth Premier League goal against his former club, a record bettered by no other former Chelsea player, making them his favourite opponent.

Victory put City 13 points clear of Chelsea, and that could yet remain their lead at the summit if Liverpool cannot beat Brentford on Sunday.

De Bruyne now has six league goals this season, as many as he managed in 2020-21, though Guardiola's post-match praise also suggested the City boss does not think his talisman has been playing at his highest level.

"We spoke together and said since we were together, from day one, all we have won and what we have done, we have done it together," Guardiola told BT Sport.

"I want to push him to do it more, he's a world-class player. He has the humility to do everything for the team, and it's not easy to find that.

"He won three Premier League titles and lots of prizes but I still want more of him because I know he can do it. Today the action he has done, I haven't seen it in a long time.

"He has everything. He missed a bit of confidence this season and struggled. He knows what he can do, he's incredibly beloved from all of us.

"He's completely different. His mum and dad can be so proud."

Despite the victory increasing City's lead, Guardiola is not getting sucked into the trap of declaring the title race over.

"That would be a problem now, to [take the gap] for granted," he said. "If Liverpool win the games in hand, it's eight points, not like Chelsea's position.

"Now my job is take from the brains of my players, to not believe what the people say. An example is recently we were winning against Leicester 4-0 after 45 minutes then in 20 minutes it was 4-3.

"We are more than pleased with our position but we've a lot of work to do. My job is to tell them."

The Premier League clash between Tottenham and Arsenal on Sunday has been postponed following a request from the Gunners.

Mikel Arteta's side asked the league to reschedule the match as they said they would not have the minimum requirement of 13 outfield players and one goalkeeper.

Arsenal lodged the appeal after Martin Odegaard tested positive for coronavirus on Thursday. Under Premier League rules, clubs can apply for a match to be postponed "if COVID-19 infections are a factor in their request".

The Gunners were also set to be without the suspended Granit Xhaka and the injured Cedric Soares, Emile Smith Rowe and Bukayo Saka.

They are also missing four players due to Africa Cup of Nations commitments, with Pierre-Emerick Aubameyang, Thomas Partey, Mohamed Elneny and Nicolas Pepe with their countries in Cameroon.

In a statement on Saturday, issued a little over 24 hours before the game's scheduled kick-off time, Arsenal said: "We are disappointed to announce that Sunday’s north London derby at Tottenham Hotspur has been postponed.

"We know how much this match means to our fans around the world, but the Premier League has made the decision to postpone the match, due to many players across our squad currently being unavailable as a result of COVID-19, existing and recent injuries, in addition to players away with their countries at AFCON.

"We apologise to our fans for any disappointment and inconvenience caused."

The decision to postpone the game came a few days after Burnley successfully appealed to have their match with Leicester City rearranged due to COVID-19 cases and injuries, the Clarets having also sold striker Chris Wood to Newcastle United this week to leave them further short on numbers.

Chelsea boss Thomas Tuchel, whose side had a request to move their match with Wolves last month rejected, said on Friday he would be "very angry" if it emerged that rules around postponements were not being applied consistently.

"We are doing everything to make games happen and we were made to play when we thought maybe we should not. So I can only strongly hope the rules are the same for everybody," Tuchel said.

Former Manchester United defender Gary Neville tweeted on Sunday: "What started out as postponements due to a pandemic has now become about clubs not having their best team.

"The Premier League must stop this now, draw a line in the sand and say all games go ahead unless you have an exceptional amount of CV cases. It's wrong."

Chelsea already knew the odds were slim. No team that has been clear by at least 10 points at the top of the Premier League after 21 matches has ever failed to lift the trophy.

The Blues travelled to leaders Manchester City on Saturday exactly 10 adrift and desperate to improve on their showing against Pep Guardiola's men from earlier in the season.

But a familiar foe once again brought their downfall as City sealed a 1-0 win that further increases their lead at the summit and probably has them over the horizon in the title race – at least as far as Chelsea are concerned.

Thomas Tuchel spoke with great clarity and assuredness as he addressed the media on Friday, accepting Chelsea were far too negative in their 1-0 defeat to City at Stamford Bridge earlier in the season.

We say "defeat", but in reality it was as close to a 1-0 battering as they come. City tallied three times as many shots as Chelsea (15 to five), and it was a similar story in terms of touches in the opposition's box (34 to 11).

But there was little sign of a major improvement here. Tuchel flailed and flapped like a headless chicken on the touchline, his instructions ultimately powerless against a City side that smothered Chelsea with a high press that just seemed to suffocate them more as the game went on.

Initially, as much as anything, Chelsea just looked confused. Their bravery in playing out from the back was to be commended in some instances, but that mentality seemed to be completely at odds with almost everything else they did.

They would get into the midfield but then launch long balls out wide or to Christian Pulisic in the hole rather than for Romelu Lukaku to run onto. The moves would go nowhere.

There was no period of sustained pressure from Chelsea at all in the first half – in fact, they got to the interval without registering a single shot, the first time that's happened in a league game under Tuchel.

Lukaku, bar one early instance where he rolled John Stones before mucking up the final pass, cut a frustrated figure up top. While Chelsea's play in the build-up largely seemed unlikely to get the best out of him, his team-mates might have expected more attempts to run in behind the City defence.

The second half was just a few minutes old when such a situation did present itself, with Lukaku able to do what he's best at: running on to throughballs rather than acting as a target man.

Ederson produced a fine save to block Lukaku's effort, but it was the clearest evidence yet of how Chelsea were likely to hurt City – not that it was necessarily a sign of things to come for the visitors.

If anything, it served as a jolt for City, a reminder that, as good as they are, they weren't going to be able to sleepwalk to a win here.

City allowed Chelsea more of the ball, but Guardiola's men upped the intensity significantly with their pressing – the Blues started to find passing through the midfield rather trickier.

Eight of the nine times City won possession in the final third (Chelsea only did so once in the whole game) came in the second half, which was not only evidence of how they were able to impressively dig deep physically, but also highlighted how a team can take the game to an opponent even without the ball.

Of course, City relied on a moment of pure inspiration, which was somewhat predictably delivered by Kevin De Bruyne, who strode away from N'Golo Kante and saw his gorgeous curling effort find the bottom-right corner from 25 yards.

It was his fifth Premier League goal against Chelsea, making his old club his favourite opposition in that regard, and a figure bettered by no other former Blue in the competition.

In the context of the match, it also highlighted the differing fortunes of players with comparable pasts: both De Bruyne and Lukaku joined Chelsea as youngsters and ultimately failed to make an impression.

The midfielder now regularly lights up the Premier League, but his international colleague is back at Stamford Bridge and struggling again, albeit for different reasons.

But the fact of the matter is, Lukaku was brought back to turn Chelsea into title contenders – that now looks impossible thanks to another familiar face.

Kevin De Bruyne hit a scorching winner as Manchester City extended their Premier League lead to 13 points with a 1-0 victory against second-placed Chelsea.

A tightly contested game at the Etihad Stadium on Saturday came to life 20 minutes from time as De Bruyne intervened decisively.

Chelsea did not see much of the ball but had their chances to get on the scoresheet too, with Romelu Lukaku and Hakim Ziyech particularly wasteful on the counter-attack.

Pep Guardiola's City have now won 12 league games on the bounce, and it is difficult to see how they can be denied making it back-to-back titles in May.

City dominated much of the first half but were grateful for poor decision-making and execution from Lukaku and Ziyech on two occasions as Chelsea looked to counter early on.

The best chance for the hosts in the opening 45 minutes came when an effective high press set Jack Grealish through on goal, but Kepa Arrizabalaga deflected the £100million man's shot behind with his left leg.

The visitors should have taken the lead two minutes into the second half when Lukaku was sent clear by Mateo Kovacic, but Ederson palmed his shot away before Ziyech lifted the rebound over the bar.

The league leaders finally broke the deadlock in the 70th minute when former Chelsea man De Bruyne cut in from the left side before expertly firing past the despairing dive of Arrizabalaga from 22 yards.

The Blues tried to find an equaliser, but City showed their solid side to clinch the three points, moving a significant step closer to lifting the Premier League trophy once more.

Novak Djokovic was back in detention on Saturday night as he awaited decision day in his battle to play at the Australian Open.

The end of the saga should come on Sunday when Djokovic's lawyers attempt to prevent the Serbian being deported.

A procedural hearing, where the matter was formally transferred from the Federal Circuit Court to the Federal Court of Australia, saw an 09:30 AEDT (Saturday 22:30 GMT) start to the case agreed upon.

Djokovic's lawyers secured an early procedural victory when it was decided the case should be heard by a full court, consisting of Chief Justice James Allsop, Justice Anthony Besanko and Justice David O’Callaghan.

That reduces the avenues for any possible appeal against the court's decision. Stephen Lloyd, who was appearing on behalf of immigration minister Alex Hawke, had indicated his preference for a single judge.

A central tenet of the case is set to be Hawke's assertion that Djokovic should be removed from the country "on health and good order grounds" and "in the public interest".

In submissions to the court issued by Djokovic's lawyers, Hawke is shown to say that he accepted the world number one recently tested positive for COVID-19.

However, Hawke adds that: "I am concerned that his presence in Australia, given his well-known stance on vaccination, creates a risk of strengthening the anti-vaccination sentiment of a minority of the Australian community."

The nine-time Australian Open champion's visa was revoked for a second time on Friday despite Djokovic winning his initial case on Monday.

His lawyers will dispute the minister's claims and push for Djokovic to be freed from detention to be able to defend his title at Melbourne Park.

In their application to the court, Djokovic's legal team state: "There was no evidence before the respondent that Mr Djokovic had made any comments about his vaccination status or expressed any 'views' regarding vaccination at any time during which he has been in Australia (on this occasion or previous occasions) or at any other time in any other location (post April 2020)."

For Djokovic, lawyer Nick Wood said on Friday that his client was of "negligible risk", "of good standing" and had a medical contraindication to a vaccine.

The Australian Open starts on Monday, when Djokovic hopes to begin his journey to what could be a 10th Melbourne slam and a record-breaking 21st major title.

Djokovic is scheduled to face countryman Miomir Kecmanovic in the first round.

Sequels, necessary or otherwise, tend to be widely popular. Whether it's in the world of boxing or on the big screen, audiences are consistently drawn in by the prospect of a second act.

But they are not quite as keenly anticipated in the NFL playoffs.

When it gets to January, there is a desire to see matchups that have not been witnessed in the regular season. That is a small part of the allure of the postseason.

Yet the opening day of 'Super Wild Card Weekend' will serve up one sequel and the third and final act of an AFC East trilogy.

Even though the first playoff games of the 2021 campaign are repeats, there is reason to believe they will be compelling. Here Stats Perform previews Saturday's action.

Las Vegas Raiders @ Cincinnati Bengals

The Raiders' visit to Cincinnati sees a matchup of two quarterbacks playing in their first postseason game, albeit at markedly different stages of their careers.

Raiders quarterback Derek Carr helped a team then based in Oakland to reach the playoffs in 2016, only for him to then miss out on their Wild Card defeat to the Houston Texans due to injury. Carr has made 127 career regular-season starts. Only two quarterbacks have ever had more prior to their first playoff start: Fran Tarkenton (174) and John Brodie (134).

Meanwhile, Joe Burrow led the Bengals to the playoffs in just his second season in the NFL and goes into his postseason debut in red-hot form. He has 971 passing yards, eight touchdowns and no interceptions over his last two games. This is the 49th instance of a player having at least eight TD passes and no INTs over a two-game span. Burrow has the most passing yards of those 49 instances, over 100 yards more than the next closest (Ben Roethlisberger, 862 in 2014).

Burrow was the most accurate quarterback in the NFL by well-thrown percentage (min. 200 attempts) in the regular season. He delivered an accurate well-thrown ball on 86.5 per cent of attempts, though in Carr he must outduel the man third on that same list (82.1 per cent).

Should he do so, Burrow will give the Bengals their first playoff win since the 1990 campaign. They have lost eight straight playoff games, while their span without a playoff win is the longest active streak in the NFL, and the fifth-longest streak in NFL history. Only one team ever lost nine straight playoff games: the Detroit Lions, who have lost their last nine postseason games.

New England Patriots @ Buffalo Bills

The Patriots and the Bills playing for the third time in a little over a month may feel repetitive, but this game actually marks a playoff first.

It is the first playoff game since the NFL-AFL merger in 1970 in which the Pats and Bills have met.

Their lone playoff clash was an AFL tiebreaker in 1963, after the teams finished the season tied for first place in the Eastern Division (both 7-6-1). The Boston Patriots won that playoff game, 26-8, at Buffalo's War Memorial Stadium.

With lows of minus 16 degrees Celsius expected in Buffalo on Saturday, a low-scoring close game would not be a surprise. The Bills (289) and Patriots (303) are ranked one-two in the NFL this season in fewest points allowed. Buffalo allowed the fewest passing touchdowns (12), and New England tied Denver for the fewest rushing touchdowns allowed (nine).

Yet if the Bills come out on the right side of the ledger, recent history suggests they will do so by a double-digit margin.

The Bills won 11 games this season and all their wins were by at least 12 points. Buffalo's average victory margin (22.1 points) was the highest in the NFL (New England: 2nd at 21.4).

Thanasi Kokkinakis fought back from a set down to beat Arthur Rinderknech and claim a maiden ATP Tour title at the Adelaide International 2 in his hometown.

Kokkinakis was beaten by Gael Monfils in the semi-final of the Adelaide International 1 last weekend, but the 25-year-old got his hands on the trophy on Saturday after a 6-7 (6-8) 7-6 (7-5) 6-3 win.

The Australian saved two match points in a semi-final defeat of Marin Cilic and showed his fight again to deny Rinderknech a first title.

Kokkinakis has had a tough time with injuries since rising to a career-high ranking 69 as a teenager in 2015, but he has shown what he is capable of early in the season ahead of the Australian Open.

There were no break point in the first two sets, but Frenchman Rinderknech failed to hold twice in the decider on a special day for Kokkinakis.

Kokkinakis said: "I wouldn't want to win my first title anywhere else. To my family, friends and coaches, what a ride it's been. You have seen me at my lowest lows and now the highest high. It's been a serious journey. For now, I am so happy.

"I've been playing and practising on this court since I was eight or nine years old, coming here before school every day. I love this court so much."

Kokkinakis will play qualifier Yannick Hanfmann in the first round of his home grand slam next week, while Rinderknech takes on Alexei Popyrin at Melbourne Park.

Genoa have sacked Andriy Shevchenko only two months after appointing the Milan great as head coach.

The Ukrainian was hired to replace Davide Ballardini on November 7, with his appointment one of the first major decisions made by the club's new ownership group.

Shevchenko had left his role as Ukraine coach in August, having taken his country beyond the group stage of a European Championship for the first time in their history at Euro 2020.

However, Genoa's form has shown no sign of improvement under the former Chelsea and Milan striker.

In nine Serie A games, Shevchenko did not preside over a single victory – they amassed three points and as many goals in that time.

His sole win in charge came via a slender 1-0 success over Salernitana in the Coppa Italia last month.

It was thought Genoa's performance in the 3-1 extra-time defeat to Milan in the Coppa on Thursday might have bought him more time.

But those reports ultimately proved inaccurate, with his former stomping ground San Siro being where his fate was settled.

Madison Keys overpowered Alison Riske to score a crushing win in Saturday's Adelaide International 2 final.

A 6-1 6-2 victory for Keys at Adelaide International 2 gave her a sixth WTA Tour title and a first since a stunning run in 2019 at Cincinnati.

Keys, who faces a tough Australian Open first-round clash against 2020 champion Sofia Kenin, showed her form is coming back after a lean spell.

The former world number seven has slipped to a lowly 87th in the rankings, but at the age of 26 she has ample time to climb back towards the top of the game.

This win moves her back into the top 60, with Elina Svitolina and Coco Gauff among the players Keys has fended off this week.

Keys said: "I'm really happy with how today went. There were a couple of opportunities where momentum could have switched, and I think I did a really good job of just regrouping and continuing to focus on my side of the court. Really happy to get a win."

Keys explained her mindset had been "dark" at times in 2021, with her appetite for tennis ebbing away.

She said: "Just knowing from what I was thinking about last year and the deep, dark pit of despair that I put myself into because of that, I don't want to go back to that. I don't want to let myself borderline hate being on the tennis court and hate competing. If I let myself think that way, that's where it goes."

Her motivation is on an upwards curve now, and results like this will help. Keys held serve throughout, did not face a break point, and broke Riske's delivery four times on the way to sealing victory in an hour and six minutes.

Quoted on the WTA website, Keys added: "I think the biggest takeaway is that things can switch at any moment. As long as you can continue to have the right mindset and keep going for things and keep working hard, things will get better if they're not going well, as long as you just have the right mindset and continue to have a good attitude about it."

Aslan Karatsev failed to read the script as he beat Andy Murray in straight sets to win the Sydney Classic on Saturday.

Three-time grand slam champion Murray had rolled back the years to reach his first ATP Tour championship match since beating Stan Wawrinka in Antwerp back in October 2019.

There was to be no 47th ATP Tour singles title for the Briton at Ken Rosewall Arena, though, as Karatsev won 6-3 6-3 to ensure he will start the Australian Open next week with a spring in his step.

The world number 20 from Russia was a surprise semi-finalist in the first grand slam of the year at Melbourne Park last year and looks capable of making his presence felt again.

Karatsev struck 27 winners to 13 from the racket of former world number one Murray, who was unable to break the Vladikavkaz native's serve.

Murray failed to hold in the first game of the final and the opening set was over when he was broken for a second time.

Karatsev surged into a 3-0 lead in the second set and fended off five break points before finally holding to take a 4-1 lead, then went on to serve it out as he secured a third ATP Tour singles title, having been triumphant in Moscow and Dubai last year.

Murray will take great heart from the strides he has made this week and three years after fearing he may be force to retire at the Australian Open, the 34-year-old will face Nikoloz Basilashvili in the first round of the 2022 tournament next week.

Karatsev will do battle with Spaniard Jaume Munar for a place in the second round at Melbourne Park.
