Edinson Cavani will miss the first leg of the Champions League last-16 tie between Manchester United and Atletico Madrid.

The striker is still being troubled by a groin problem, having missed the Red Devils' past three Premier League matches.

Interim manager Ralf Rangnick said the Uruguay international has been unable to train for two weeks and does not feel capable of running at full capacity, meaning there is little point in including him in the squad for Wednesday's match.

"No, Edi will not be able to make the trip," he told reporters on Tuesday. "He didn't train and hasn't been training for the last couple of weeks.

"He has problems with his groin and as long as he doesn't feel ready to fully sprint, it doesn't make sense to train him."

Cavani has scored two goals in 11 games in a season blighted by persistent unavailability.

Having been persuaded to stay at the club for another year by Ole Gunnar Solskjaer after impressing in 2020-21, Cavani has missed 20 of United's 35 matches in all competitions, last playing in the 1-1 draw at Burnley on February 8.

United allowed Anthony Martial to join Sevilla on loan in January but did not sign a replacement, meaning 37-year-old Cristiano Ronaldo will be their only recognised centre-forward for the game at the Wanda Metropolitano.

The Portugal star has scored 25 goals in 35 appearances against Atleti in his career, netting three hat-tricks against Diego Simeone's side, two in the Champions League.

Rangnick, whose side battled to a 4-2 league win at Leeds United on Sunday, said: "We have made sure the players could recover in the last few days and maybe we will have some fresh legs on the pitch. We will see tomorrow.

"Some of our players will not be received with the red carpet. We have some experience and some talented young players, so the balance is perfect.

"Mentally, we need to prepare for a very emotional, if not hostile, atmosphere. I don't think the game or the fixture will be decided tomorrow, it will be decided in the second leg at Old Trafford.

It remains unclear whether Aaron Rodgers has played his last snap as a Green Bay Packer or on a football field, and he is clearly happy to let the NFL universe continue to do the guessing.

The four-time MVP fuelled speculation over his future on Monday with a cryptic Instagram post thanking team-mates including Randall Cobb and David Bakhtiari, coaches and his ex-fiancee Shailene Woodley for the experiences of "the last beautiful year".

Rodgers, who won the MVP award for the second successive season in 2021, wrote: "Here's some... #MondayNightGratitude for some of the incredibly special people in my life, with some pictures from the last beautiful year.

"@shailenewoodley, thanks for letting me chase after you the first couple months after we met, and finally letting me catch up to you and be a part of your life.

"Thanks for always having my back, for the incredible kindness you show me and everyone you meet, and for showing me what unconditional love looks like, I love you and am grateful for you.

"To the men I got to share the QB room with everyday, Matt [LaFleur], Nathaniel [Hackett], Luke [Getsy], @jordan3love and @kurtbenkert, you guys made every day so much fun and I’m so thankful for the daily laughs and stress relief you brought me every week of the year. I love you guys.

"To the Friday Crew, @aiydacobb, @rcobb18, @frankieshebby, and @davidbakhtiari, I loved every moment we got to spend together this year. Your love and support was overwhelming, and I cherish the friendships I have with each of you.

"To my team-mates, past and current, you are the icing on the beautiful cake we call our job; football. The friendships that we have will transcend our collective time in this game and I am so thankful for the role that each of you have played in making my life that much better. I love you guys, and cherish the memories we've made.

"To everyone else, spread love and gratitude you beautiful people, and read a book once in a while too while you’re at it. Love and peace."

It was reported before the opening round of the 2021 NFL Draft that Rodgers wished to part with the Packers. The subsequent stand-off and Rodgers' absence from their offseason activities cast a shadow over the Packers' pre-training camp preparations for the season.

After reporting for camp, Rodgers' 2021 campaign was partly defined by controversy after a positive coronavirus test revealed previous misleading statements about his vaccination status, while his spread of misinformation regarding vaccines has unquestionably damaged his reputation.

On the field, he helped the Packers to an NFL-best 13-4 record in 2021, finishing the regular season with 37 passing touchdowns to just four interceptions, giving him the best touchdown to interception ratio in the NFL. Among quarterbacks with 200 passing attempts, only Justin Herbert (2.30) threw a lower percentage of interceptable passes than Rodgers (2.36).

No quarterback delivered more throws that resulted in a first down than Rodgers, who did so on 40.1 per cent of his attempts, while he was second in passer rating on third down (112.2) behind Kyler Murray (118.5) among quarterbacks with at least 50 attempts in that situation.

His stellar play in the regular season did not translate into the postseason, with the Packers going one and done as they suffered a 13-10 Divisional Round upset at the hands of the San Francisco 49ers.

Since Rodgers led the Packers to glory in Super Bowl XLV at the end of the 2010 season, they have reached the Divisional Round of the playoffs eight times but have never returned to the Super Bowl.

Tottenham boss Antonio Conte has taken aim at his Manchester City counterpart Pep Guardiola after Spurs' 3-2 Premier League win at the Etihad Stadium.

Conte mocked the latter's assertion that Tottenham played on the counterattack during their dramatic victory in a post on Instagram.

Harry Kane and Son Heung-min starred as Spurs grabbed a last-gasp win at the home of the Premier League champions, despite twice having squandered a one-goal lead.

Each of Tottenham's last three wins in the Premier League have now come courtesy of 90th-minute goals (1-0 v Watford, 3-2 v Leicester City, 3-2 v Man City), as Spurs kept pace with their rivals in the hunt for Champions League qualification.

After the contest, during which the visitors managed just 29 per cent of the possession and racked up six shots to City's 21, City boss Guardiola told of how the north London team had "defended in the 18-yard box" before catching the league leaders on the break.

Conte has now moved to mock those assertions on social media after dealing City their first Premier League defeat since October.

On his personal Instagram account, Conte posted a video of his team's three goals in the match, displaying the complete build-up to each, with the caption "Counterattacks?!? Maybe not…", complete with three laughing emojis.

The former Juventus, Chelsea, and Inter boss has led Tottenham to 11 wins in 20 matches since taking charge across all competitions, with their comeback win in Manchester ending a run of three successive league defeats for the top-four contenders. 

Spurs will continue their chase for European football when they face Burnley at Turf Moor on Wednesday, having only lost one of their last 12 Premier League meetings with the Clarets.

UEFA could decide to move the Champions League final from St Petersburg as European football's governing body closely watches the escalating crisis in Ukraine.

The 2022 final is scheduled to take place in Russia's second-largest city, one of the main venues during the 2018 World Cup and Euro 2020, on May 28.

UEFA's present position is to hold the Champions League final in St Petersburg, but it is understood the situation could change, even at short notice. The previous two finals were moved due to the COVID-19 pandemic.

European football's governing body said in a statement on Tuesday: "UEFA is constantly and closely monitoring the situation. At present, there are no plans to change the venue."

Staging European football's most prestigious club match in Russia has become more difficult following the decision by Vladimir Putin, the country's president, to order troops into eastern Ukraine.

Russia's military was sent into the region on "peacekeeping duties" after the decision to recognise the areas of Luhansk and Donetsk as self-proclaimed independent states loyal to Moscow.

Last season's final between Chelsea and Manchester City was relocated to Porto from Istanbul with only two weeks' notice. This was because Turkey was on the United Kingdom's 'red' list, meaning fans were urged not to travel for the game due to coronavirus risk levels.

Alexander Zverev saved a match point and battled back to salvage a dramatic victory over Jenson Brooksby at the Mexican Open in what was the latest finish in tennis history.

Second seed Zverev – the defending champion in Acapulco - wrapped up a dramatic win at 04:55 local time after his own lengthy contest had followed two other epic three-setters earlier on the schedule.

Zverev at one stage looked like he was on the way out but ultimately triumphed 3-6 7-6 (12-10) 6-2 to book a second-round tie against Peter Gojowczyk.

The German had beaten Brooksby in a match that also went to a decider when they clashed at Indian Wells in October and he was pushed to the limit again in a battle lasting 200 minutes.

Having dropped the first set, Zverev had to fend off three break points at 3-3 in the second and saved a match point at 6-5 as part of an epic tie-break that went in his favour. 

Zverev was then more comfortable as he broke twice in the decider to seal victory, his American opponent paying the price for converting just one of his seven break-point opportunities in a match that made history for its late finish.

Elsewhere, Stefan Kozlov overcame cramps in the second set to outlast Bulgarian Grigor Dimitrov 7-6 (10-8) 5-7 6-3, with that match lasting three hours and 21 minutes.

John Isner sent down 29 aces and saved a match point as he trailed 5-2 in the third set, ultimately winning 7-5 6-7 (4-7) 7-6 (7-3) over veteran Fernando Verdasco in another epic topping the three-hour mark that helped to push back the start time for Zverev and Brooksby.

Seventh seed Taylor Fritz got past Frenchman Adrian Mannarino 6-3 6-3, while Dusan Lajovic knocked off Sebastian Korda 6-4 4-6 7-5 and eighth seed Pablo Carreno Busta beat Oscar Otte in straight sets.

At the Chile Open in Santiago, eighth seed Facundo Bagnis won 6-3 6-0 over Bernabe Zapata Miralles in the round of 32.

Brazilian Thiago Monteiro got past local Nicolas Jarry 7-6 (11-9) 6-4, while qualifier Juan Ignacio Londero and wildcard Thiago Seyboth Wild also progressed.

Novak Djokovic welcomed the "positive" reception he has received from his fellow players, after making his first appearance since missing the Australian Open.

Djokovic, whose decision not to be vaccinated against COVID-19 caused him to be deported from Australia on the eve of the year's first grand slam, eased to a 6-3 6-3 win over Lorenzo Musetti in just 74 minutes at the Dubai Tennis Championships.

Djokovic spoke publicly about his vaccination status for the first time in a BBC interview last week, while rival Andy Murray, who has spoken about his support for vaccination on numerous occasions, said that he "didn't like seeing" Djokovic's ordeal in Australia after his own win in Dubai.

Serbia's 20-time Grand Slam winner says that most of his fellow professionals have been supportive upon his return to action.

"So far here most of the players that I’ve seen – I haven’t seen too many players – but most of the players that I've seen have been positive and welcoming", he said after his round-of-32 win.

"It's nice to see, obviously. I can't say that was the case in Australia. It was a little bit strange. But here, it's gone well so far."

The 34-year-old impressed against Musetti, serving five aces, winning 71 per cent of his second serves (17 out of 24) and saving each of the seven break points he faced during his first outing of the year, and Djokovic was also pleased with the reception he received from the fans in Dubai, as well as with his performance. 

"I couldn't ask for a better reception," he added.

"It's been a while since I played, and I couldn't think of a better place to kick-start the season. Thank you for the reception and for welcoming me on court the way you did.

The Pittsburgh Steelers are intrigued to see what Mason Rudolph can do but will still be adding to the quarterback position this offseason.

After the retirement of Ben Roethlisberger, Pittsburgh have uncertainty over their regular starter at QB for the first time since the two-time Super Bowl winner was drafted in 2004.

Rudolph was backup to Roethlisberger over the past three seasons and has started 10 games over that span, while former Washington first-round pick Dwayne Haskins is expected to stay with the team.

The Steelers will also bring in another option, either via free agency, trade or the NFL Draft, but outgoing general manager Kevin Colbert was positive about Rudolph.

"Mason's 5-4-1 as an NFL starter, albeit in a backup kind of role, but we are excited to see what is next for Mason," said Colbert, who will step down as GM after the draft process, per ESPN.

"If we started a season today, Mason would be our starter, and we're excited to see where that can go. I'm comfortable that Mason has won more games than he's lost as a starter.

"Where that can go, we'll see. To be an NFL starter that you can win with, you gotta prove it over 16 games. I'm anxious to see that, if that's the case.

"And we're excited to see what Dwayne can provide either from competition, or maybe he evolves as a starter."

Jimmy Garoppolo has been linked as a possible trade candidate, while the Steelers have the number 20 pick in a draft which does not have a consensus top QB expected to go at the top of the order.

Colbert added: "We know we're going to add to the position. I can't tell you how, but at this point we will go to camp with four [QBs].

"If we had to start today with Mason as our starter, let's go. We'll try to build the best team around him."

Malik Willis, Sam Howell and Kenny Pickett are among the draft prospects Pittsburgh are likely to be doing due diligence on.

"The draft class of quarterbacks, there's good quality available – probably not as many as there have been in recent years, but it is what it is," added Colbert.

"This group, there's good players in it and there's good players that all have a different skill set. 

"That's what was really unique about watching them compete at the Senior Bowl, because the majority of them were there, and they're all different. 

"I know some of them will be starting quarterbacks, winning quarterbacks, and that's exciting."

Fernando Alonso is relishing the new regulations in Formula One for 2022, saying they give teams hope that "everything can change".

Alpine released their new car for the year in Paris on Monday and the 40-year-old is in an optimistic mood.

The team finished fifth in the constructors' championship last season, with Esteban Ocon winning a dramatic race in Hungary.

Alonso hopes the varying new rules will help to level the playing field and make that kind of result more common.

"Second year with Alpine and yeah, I'm more optimistic than last year, probably because the new rules give you that hope that everything can change," Alonso said.

"You can certainly be competitive from race one. So, I'm optimistic, confident. The team did a good job with the car and we're ready to go.

"I'm very excited about the new regulations. Obviously, from time to time, Formula One change [the regulations] and try to mix a little bit of performance from everybody.  

"And for Alpine or some of the midfield teams that we were last year, there is an opportunity for sure. 

"If we do a good job interpreting the rules and maximising every opportunity, this year is going to be important. So, everyone in the team feels that we can do it and we are ready to go.

"Probably the best thing or the hope is that we can follow each other closer on track, so maybe that provides more action, more overtaking opportunities, close fights and that's probably better for everybody, for the show, for the spectators, but also for us drivers.

"We have been asking for closer racing between cars, especially in the corners. We will have to wait and see if these regulations allow closer racing, but I will never be upset with the idea of more exciting racing. 

"The sport is moving in the right direction off track too, thanks to the introduction of things like a budget cap. We hope it can bring more fairer racing to stop others outspending the rest."

While Ocon got the race win last year, he still finished behind veteran Alonso, who came 10th in the drivers' standings.

The Spaniard says he has a close bond with his younger team-mate.

Alonso added: "The relationship with Esteban has been better and better from race one last year.

"Until now, race one this year, over 2021 I think we had good fun together, we work together, and we understood that it's the best thing for the team and for the performance of ourselves as well. 

"And yet during the winter it was a long period that we didn't see each other so we were texting sometimes, and we have a WhatsApp group, and we were having fun and obviously missing each other a little bit.

"So now it's time to race again together and help the team to move forward.

"The new car – I really like the livery, I like the colours, the combination. Obviously, the technical side of it, we have to keep it secret and we have to first hit the track and see how it behaves."

If Liverpool Football Club were to sign even 10 per cent of the players they get linked with, Jurgen Klopp would have a squad of around 250 players.

However, one name that seemingly refuses to go away from back-page transfer talk concerning the Reds is that of Leeds United winger Raphinha.

The Brazilian has been a sensation since arriving at Elland Road in 2020 from French side Rennes, getting the fans on their feet to marvel at the quickness of his feet.

Unfortunately for Leeds, the natural order of things often means that any club outside of the so-called 'big six' in England who unearth a star player usually end up struggling to keep hold of them for too long.

Links with Manchester United and Chelsea have also not been too far away, but ahead of Marcelo Bielsa's team heading to Anfield to take on Liverpool on Wednesday, Stats Perform looks at whether Raphinha could potentially be a future fit on Merseyside.

Small matter of Salah

If Raphinha ever finds himself dreaming of turning out at Anfield, the dream probably ends with him being chased around by a giant Mohamed Salah until he wakes up in his Billy Bremner pyjamas in a cold sweat.

It is safe to say that as long as Salah is contracted to Liverpool, he will be the main man on the right-side of their attack.

The Egyptian scored his 150th goal for the club in the 3-1 win over Norwich City on Saturday, with only Roger Hunt (226) reaching the landmark in fewer games than Salah's 233.

Salah is adored by the Kop and is showing no signs of slowing down, currently sitting way ahead in the Premier League scoring charts for this season on 17 goals, five ahead of second-placed Reds team-mate Diogo Jota.

However, questions over his future have arisen with less than 18 months remaining on his current contract.

Liverpool and Salah's representatives are in talks to extend it, but as of now, there appears to be no breakthrough in negotiations for a player who can deservedly request to be among the world's highest-paid stars.

Salah insists it is not about the money, recently saying in an interview with GQ: "I want to stay, but it's not in my hands. It's in [Liverpool's] hands. They know what I want. I'm not asking for crazy stuff.

"I've been here for my fifth year now. I know the club very well. I love the fans. The fans love me. But with the administration, they have [been] told the situation. It's in their hands."

Forward planning by planning for forwards

Liverpool are well-known for planning ahead and building for the future.

Luis Diaz's arrival from Porto had been earmarked for the summer but was moved forward to January after Tottenham made a bid for the Colombian, and now Klopp already has his succession plan in place for Sadio Mane, who is also out of contract in 2023.

Roberto Firmino's deal is another set to be up next year, but in Jota, Liverpool already have someone else for that role too, but Salah's position is still very much his own.

Harvey Elliott has shown plenty of promise, though Klopp appears to be trying to reinvent the 18-year-old as a midfielder, while big things are also expected of 17-year-old Kaide Gordon, but it would be a big ask for the former Derby County youngster to step up any time soon to fill what would be a huge void.

Klopp is reportedly a big admirer of West Ham's Jarrod Bowen, but his form this season has likely seen his price skyrocket beyond what Liverpool would be willing to pay.

Raphinha has apparently been watched by the club's scouting team since his appearances at the 2016 Copa Sao Paulo with Avai, but it was Leeds who pulled the trigger on bringing him to the Premier League after stints with Vitoria Guimaraes, Sporting CP and Rennes.

As with Diaz and Jota (and to an extent, Bowen), Liverpool waited for a player they had been watching for a long time to prove themselves at a higher level, and there is little doubt that Raphinha has managed to do so.

Impressing in the Premier League

Since arriving in England, the 25-year-old – who is only a month older than Diaz – has scored 15 goals and registered 11 assists, already hitting nine goals this season having managed six in his first campaign.

Only Bruno Fernandes (160), Trent Alexander-Arnold (133), Mason Mount (115) and Kevin De Bruyne (111) have created more chances in the Premier League since Leeds bought him than his 107, while only Allan Saint-Maximin (318) and Adama Traore (306) have attempted more than his 245 dribbles.

Raphinha has been integral to Leeds, particularly this season. By Christmas Day, he had scored 44 per cent of his team's league goals (eight out of 18).

Of course, his goal output pales in comparison to Salah's, who has 34 goals (six penalties) in 56 Premier League games in that time, and 14 assists.

He has attempted more dribbles than Salah's 176, and his 104 completed dribbles beats Salah's 69, though there is undoubtedly more onus on Raphinha to force openings for Leeds than Salah at Liverpool, where he has a bit more help, particularly with Alexander-Arnold backing him up from right back.

There has already been talk that the Yorkshire club are looking to extend his current deal, but of late, things have not been quite as rosy between player and club.

He did not score in any of Leeds' first six games of 2022 and was subbed at half-time in the 3-0 defeat at Everton last week, before not even making the starting line-up for the visit of Manchester United on Sunday.

With his team 2-0 down, Bielsa brought Raphinha on at half-time and he made an instant impact, with his goal making it 2-2 within nine minutes of arriving in the game, though it would ultimately end in a 4-2 loss to their old rivals.

There is also the fact that, for all of the player's contributions, there must be some frustration that his goals so often end with zero points on the board.

Four of the nine Premier League games in which Raphinha has scored for Leeds this season have ended in defeat – no player has scored in more losses so far this term.

Of course, the issue if he were to move to Liverpool would be game time. He would see a lot more of their subs' bench than he does at Leeds, but with more games in their calendar thanks to the Champions League and, this season at least, going far in domestic cup competitions, there could still be plenty of minutes to be had in spite of Salah's undroppable status.

While he is not on Salah's level yet – though you can arguably count those who are on one finger – his numbers have already improved while he has been in England and you would fancy a manager like Klopp to be able to raise that ceiling further still, even though Leeds fans might not want to listen to such arguments.

Champions League holders Chelsea get their knockout campaign started on Tuesday as the defence of their crown enters an altogether more challenging stage.

Thomas Tuchel's men may feel they have dodged a bullet or two by getting this draw, with their next opponents Lille struggling to match the highs of their Ligue 1 title victory from last season in 2021-22.

Tuesday's other encounter sees Juventus travel to Villarreal, with Massimiliano Allegri looking to improve on the knockout exploits of Maurizio Sarri and Andrea Pirlo before him.

Here, Stats Perform delves into the Opta data to pick out the key statistical narratives and subplots ahead of Tuesday's games.

Chelsea v Lille

Much of the attention at Stamford Bridge will be on Romelu Lukaku, whether the Belgian plays or not.

The big-money signing's struggles this season have been well-publicised, but he hit a new low on Saturday as he touched the ball just seven times in the win over Crystal Palace – that is the fewest by any player to feature for 90 minutes in a single Premier League game since at least 2003-04.

On the other side of the contest is a striker aiming to emulate Lionel Messi. Jonathan David may not have scored a Ligue 1 goal since December but the talented Canadian impressed in the second half of the group stage.

He scored one goal in each of his last three appearances in the competitions, meaning if he scores on Tuesday he will be the second-youngest (22 years, 39 days) non-European to score in four successive Champions League games after Messi (21y, 155d in November 2008).

That is not to say Lille are a high-scoring side. Many will be wondering who let Les Dogues out of Group G, given their haul of seven makes them the lowest-scoring group winners since Leicester City and Atletico Madrid (seven each) in 2016-17. In fact, no team from that section scored more than eight.

The omens are, perhaps unsurprisingly, overwhelmingly in Chelsea's favour here. Only Manchester City (15) and Bayern Munich (14) have won more Champions League games than the holders since the start of last season, while Lille are appearing at this stage for just the second time ever.

Further to that, Tuchel boasts a fine record in Champions League knockout ties, having progressed from/won (including finals) eight of his previous 11 (73 per cent), a success rate bettered by only three managers (minimum 10 knockout ties): Vicente del Bosque (80 per cent - 8/10), Jupp Heynckes (86 per cent - 12/14) and Zinedine Zidane (88 per cent - 14/16).

Villarreal v Juventus

Sarri and then Pirlo were both tasked with establishing a new era at Juventus, but when Allegri returned after a two-year break in pre-season, he picked up the pieces of a side that had regressed significantly.

There remain plenty who feel Allegri never should have been re-hired, but this tie at least gives him an opportunity to point to a degree of progress – at least in the context of the Champions League.

After all, neither Sarri nor Pirlo got beyond the last 16. Allegri, on the other hand, was only eliminated at this stage once in five seasons, and that was to Pep Guardiola's excellent Bayern side.

His counterpart on Tuesday, Unai Emery, has something of a point to prove as well, but his has more to do with his own personal record.

While something of a specialist at Europa League level, having won the competition four times including last season, he has won only one of six knockout games in the Champions League.

Much of Emery's hope will be pinned on Arnaut Danjuma.

The Dutchman – who recently returned from two months out and scored a hat-trick at the weekend – had a hand in five goals in the group stage, which is already a joint-club record for the club in the competition.

By no means are the Yellow Submarine a one-man team, however. Young winger Yeremi Pino caught the eye in the group and is plotting to become only the fourth Spanish teenager to score in the knockout stages of the Champions League after Bojan, Cesc Fabregas and Raul.

World number one Novak Djokovic has praised Rafael Nadal for his "incredible" triumph by winning last month's Australian Open after his own deportation forced him to miss the event.

Nadal moved beyond Djokovic with his record-breaking 21st Grand Slam title in Melbourne with a five-set victory over Daniil Medvedev in the final.

Djokovic was unable to compete in Melbourne due to his vaccination status, deported amid an ugly saga after arriving in Melbourne expecting to be permitted to play.

The Serbian, who returned to the ATP Tour on Monday with a 6-3 6-3 win over Lorenzo Musetti at the Dubai Tennis Championships, was gracious in praising Nadal, who had a nagging foot injury dog him late last year.

"I think it was four, five months ago that he was on the crutches and now he's winning a slam. It's incredible," Djokovic told reporters after beating Musetti.

"I've got tons of respect for him. I don't want to take anything away from his victory, me not participating in the tournament regardless."

The Serbian was pressed on missing the Australian Open and added: "Of course, it wasn't a pleasant feeling for me leaving the country the way I did and watching the tournament from far away."

Djokovic will play either Karen Khachanov or Alex de Minaur in the second round in Dubai, while Nadal is competing at the Mexican Open, with a match against Denis Kudla on Tuesday.
