Thomas Tuchel sees no reason to leave Chelsea for Manchester United despite the continued uncertainty at Stamford Bridge.

Sanctions imposed on Chelsea owner Roman Abramovich – a Russian businessman who is claimed to have links to Vladimir Putin – in response to Russia's invasion of Ukraine have impacted the club's day-to-day operations.

As they wait on a sale, the Blues cannot engage in contract negotiations or sell tickets or merchandise, while their spending in key areas such as travel is capped.

Meanwhile, United – one of the richest clubs in world football – are looking for a new manager for next season, prompting talk Tuchel could be targeted.

But the Chelsea coach, who confirmed his side would be able to fly to Middlesbrough for Saturday's FA Cup quarter-final, dismissed the suggestion.

Asked for his reaction to the reports, Tuchel said: "There's no reaction at all.

"Do you feel me [being] less committed to the club? Less involved in the club in my situation? I think absolutely not.

"I have said many times that I love to be here and I love to work for Chelsea, and this club has everything that it needs to make me happy. That's why there is no need.

"We have plenty of reasons to stay in the moment here, and that is what we're doing."

A move to Old Trafford would ensure Tuchel's ability to spend in the coming transfer window, which remains uncertain as long as he stays at Chelsea.

But the Champions League-winning coach is confident the London club will be able to stay competitive.

"Maybe players will decide something they would not have decided if the situation had been different. Okay, maybe," he said.

"But there are so many 'ifs' in this; if it comes to this, we will find a solution.

"I still believe Chelsea will stay strong, Chelsea will hopefully stay football first, will hopefully stay a team-first club. I have trust and I believe in our ability to adapt.

"We will find solutions once the situation has cleared, once we are hopefully able to act again."

Although Tuchel was previewing the Boro game – for which Reece James is a doubt, putting his England availability into question with Trent Alexander-Arnold already out – he was speaking moments after Chelsea were drawn against Real Madrid in the Champions League quarter-finals.

A clash with Atletico Madrid's tie with Manchester City could prevent Chelsea playing away at the Santiago Bernabeu in the second leg, as was initially indicated, but no change had been made as Tuchel reflected on the draw.

"It's a tough one," he said. "The challenge cannot be much higher than playing the second leg in the Bernabeu with spectators.

"It's a big challenge, but there is also big excitement around this match, around this fixture. We know what's coming. It will be an exciting match and a tough challenge."

Real Madrid will face holders Chelsea in the Champions League quarter-finals, while Manchester City tackle Atletico Madrid.

The clash of 13-time winners Madrid and two-time champions Chelsea will be a repeat of last season's semi-final, which the English side won 3-1 on aggregate, and will mean Los Blancos boss Carlo Ancelotti goes up against his former team.

Madrid's Eden Hazard and Thibaut Courtois could also face their old club, who are in a state of crisis after owner Roman Abramovich was hit with UK government sanctions.

The winners of that standout tie will progress to a semi-final against City or Atletico, who meet in a tantalising clash that will see coaches Pep Guardiola and Diego Simeone at the heart of the narrative.

Atletico beat Manchester United at the last-16 stage and will return to the north-west of England in pursuit of another major scalp.

Villarreal, who sprung a surprise by knocking out Juventus, have been rewarded with a clash against Bayern Munich, who were 8-2 aggregate winners over Salzburg.

Benfica will face Jurgen Klopp's in-form Liverpool. The Reds are six-time European champions but lost to the Portuguese giants at the last-16 stage in the 2005-06 season, their last meeting in the Champions League.

The two-leg quarter-final ties will be played April 5-6 and April 12-13, with the semi-finals scheduled for April 26-27 and May 3-4.

The Stade de France will stage the final on May 28, after St Petersburg was stripped of the match due to Russian military action in Ukraine.

Middlesbrough boss Chris Wilder believes FA Cup rivals Chelsea will believe "the world's against them" after owner Roman Abramovich was sanctioned by the UK government.

An FA Cup quarter-final at the Riverside Stadium on Saturday evening sees Chelsea go up against a Championship team who have knocked Manchester United and Tottenham out of the competition already.

Wilder, who previously managed in the Premier League with Sheffield United, will have Middlesbrough's players geed up for the occasion.

But he suspects Thomas Tuchel's Chelsea will also be determined to deliver a big performance, suggesting they have developed a "siege mentality" since the club sank into crisis.

He also believes the London club as a whole have woken up to the reality of their situation, having been roundly mocked for suggesting the Middlesbrough game be played behind closed doors.

On the pitch, Chelsea's players have shown focus since the club's crisis surfaced, beating Norwich City, Newcastle United and Lille in consecutive games.

"I've not taken too much notice about all the stuff that's happened over the last week and a half. This is an outstanding team in every aspect of the game. A squad I would imagine is worth about a billion pounds," Wilder told BBC Radio 4's Today programme.

"They've got world-class players and a world-class manager, regardless of all the stuff that's been going on. They are still in the hunt for a top-three finish and in the quarter-finals of the Champions League and the FA Cup.

"Their mentality I imagine should have been strengthened, with a little bit more of a siege mentality, that the world's against them, and they will certainly want to progress in the cup."

Chelsea were set to travel north by bus, rather than taking a private jet, with belt-tightening measures having been drawn up since the club was placed in special measures.

Abramovich has been sanctioned over links to Vladimir Putin, the Russian president, and the club have been barred from selling tickets or merchandise.

When Chelsea requested that the Middlesbrough game be played without spectators for the sake of "sporting integrity", the London club faced ridicule and soon backed down.

Wilder was baffled too, saying: "I think like 99.99 per cent of people who love the game, [I thought] 'What is going on?'," he said.

"A bit of head scratching at the time. It was a decision that was met universally with displeasure. I don't know another word to use, it was baffling.

"There was a quick turnaround in terms of what they wanted to happen, maybe checking themselves a little bit, getting a grip of themselves and saying, 'Well really this shouldn't happen', and coming to a sensible conclusion."

Since recording back-to-back Premier League wins over Jose Mourinho's Chelsea in February and August 2006, early in the Abramovich era, Middlesbrough have lost each of their last eight matches with the Blues in all competitions without scoring a single goal.

Middlesbrough will be appearing in their first FA Cup quarter-final since 2016-17, when they lost 2-0 at home to Manchester City. They have been eliminated at this stage on each of the last four occasions they have reached the final eight, since making the semi-finals in 2005-06 under Steve McClaren.

Wilder suggests Middlesbrough have only "a puncher's chance" ahead of the visit of the third-placed team in the Premier League.

"But we want to give it a good go," he said. "It wouldn't be the biggest upset in cup history, but we are certainly up against it."

Tottenham defender Japhet Tanganga has been ruled out for the rest of the season after undergoing surgery on his right knee, the club has confirmed.

Tanganga has not played since January following the injury and will now not return to action until the start of the 2022-23 campaign for the north London outfit.

"Japhet Tanganga has undergone surgery on his right knee and will be out for the remainder of the season," the club confirmed in an official statement.

"The England Under-21 international will undergo a period of recovery and is expected to return to training during the pre-season period."

Trent Alexander-Arnold will miss Liverpool's FA Cup tie against Nottingham Forest and is unavailable for England duty due to a hamstring injury, Jurgen Klopp has confirmed.

The full-back, who was named in Gareth Southgate's latest England squad on Thursday, will be forced to miss the Three Lions' March international friendlies against Switzerland the Ivory Coast.

The Reds travel to the City Ground on Sunday in pursuit of a semi-final place, a few weeks on from claiming the EFL Cup against Chelsea at Wembley.

Victory would take them one step closer to a potential quadruple, with Klopp's side still in contention for both the Premier League and Champions League too.

But they will have to do so this weekend without Alexander-Arnold, while Mohamed Salah could be a doubt for the visitors too.

"Trent is out with a hamstring, so will be out for England too," Klopp told his pre-match news conference. "[It's] not good news, [but] we will see how long it takes. Mo felt his foot a little bit after the game too."

Asked on how his side would cope without Alexander-Arnold, Klopp added: "We will see. To replace him is difficult but possible.

"We have [James] Milner, [Joe] Gomez, these kind of things. Trent is so influential but Milner has done incredibly well in the past. We'll see how [he] is for Sunday."

Liverpool are set to play their first FA Cup quarter-final under Klopp, with the trophy one of the few gaps on his resume since he arrived on Merseyside.

If he is able to guide them past Forest - themselves in the last eight for the first time since the 1995-96 campaign - then the Reds will move a step closer to further silverware this season.

Everton manager Frank Lampard revealed he broke his hand celebrating his side's remarkable 1-0 win over Newcastle United on Thursday.

A hectic game lasted for 118 minutes due to a second-half delay when a protester attached himself to the Goodison Park goalposts and could not be removed.

Everton, coming into the match outside the Premier League's bottom three only on goal difference, then had to play from the 83rd minute onwards with 10 men.

Allan was initially only booked for hacking down Newcastle substitute Allan Saint-Maximin, but the VAR advised Craig Pawson to revisit his decision, which he did – prompting howls of frustration among home players, staff and fans when the replay was shown on the big screen.

Everton had been on the back foot with 11 men and appeared ready to sit in and settle for a precious point, only for one final chance to present itself.

Seamus Coleman stole the ball from Saint-Maximin and fed Alex Iwobi, who traded passes with Dominic Calvert-Lewin before steering a low shot past Martin Dubravka for the second-latest winning goal since Opta's Premier League records began in 2006-07.

There were scenes of mass celebration both when the ball hit the net and when the final whistle belatedly blew, giving Everton their first win over Newcastle since December 2019 – albeit one that came at a cost for Lampard.

"I've broken my hand in the celebrations for the goal," Lampard told Amazon Prime, revealing a significant bruise. "It's a bit sore, a bit shaky, but I don’t care."

Prior to Thursday's win, Everton had earned only three points in six matches since Lampard's January appointment – more than Norwich City alone over that period. Newcastle's 16 points trailed only Liverpool.

"We were all waiting for this – a night of togetherness and fight and spirit," Lampard explained.

Indeed, rather than take credit for any calls he made in a game that saw Newcastle win the shot count 17-9 and dominate 61.6 per cent of the possession, the Toffees boss attributed the victory to a brilliant atmosphere on Merseyside.

I don't think it's my formations or cleverness that will keep us up," he said. "It's part of the bigger picture, but it's people and the players that will keep us up, and the fans when we get together.

"I thought the start of the game was a bit special. I know I'm new to this, an evening game at Goodison, but you could feel the crowd.

"Maybe they had a couple of pints of Guinness for St Patrick's Day. Fair play, we need that. We need them behind us.

"If we get out of this it's together, the fans and the players played their part."

Sergio Perez believes "it makes sense to have a discussion" around the idea of Formula One drivers being allowed to race with coronavirus.

The 2022 season will be the third affected by COVID-19, already impacting the grid for Sunday's opener at the Bahrain Grand Prix.

Sebastian Vettel has contracted the virus, meaning he will be absent for Aston Martin, while Daniel Ricciardo missed the end of pre-season testing but has recovered to take up his McLaren seat.

Red Bull's Perez missed two races in 2020 due to COVID-19 and suggests drivers – already isolated within their cars during races – should not be ruled out if they are otherwise fit and healthy.

"Going forward, we should discuss whether we allow the drivers to race if the symptoms are mild," the Mexican said.

"The drivers can obviously be the judge, but I think it makes sense to have a discussion.

"There is only so much you can do. I think it's just luck-dependent. It is difficult to not do anything. I'm just very sorry for Seb and for Daniel, but it can happen to anyone."

Nico Hulkenberg, Aston Martin's reserve driver, has replaced four-time world champion Vettel this week.

Duke coach Mike Krzyzewski revealed his excitement heading into his final NCAA Tournament before bringing an outstanding 42-year tenure to a close.

'Coach K' is leaving Duke at the end of this season, having been the Blue Devils' coach since 1980.

Krzyzewski was denied a 16th ACC Tournament title with defeat to Virginia Tech in the championship game last weekend, but the possibility of a sixth national title remains.

The coach's final March Madness begins with his number two seed facing 15-seed Cal State Fullerton on Friday.

"I'm just going to go for it, and that's what I've tried to do all season long," Krzyzewski said. "I just want to be in the moment. I'm excited."

While Krzyzewski is looking forward to his 'last dance', he acknowledges the emotion around each game is trickier for his Blue Devils players to deal with.

"That's part of the thing this week, is to get them mentally fresh, not just physically fresh," the 75-year-old said.

"There's a lot of emotion with all my stuff, and it's over now. That's a lot for those kids."

The East Regional section of the tournament saw a big upset on Thursday with a 15 seed beating a two seed – Saint Peter's stunning Kentucky.

And Krzyzewski is well aware of the delicate situation Duke find themselves in as they seek to prolong his coaching career.

"Most of the time, they don't realise it's one-and-done until it's done," he said.

How does Formula One go about following up the epic 2021 season?

Well, until that stunning campaign stole the show, this year was long seen as the one to look forward to with the introduction of new regulations to encourage competitive racing right down the grid.

Lewis Hamilton might have expected a genuine challenge in 2022; instead, in the form of Max Verstappen, it arrived 12 months early.

Excitement for the coming campaign is therefore at an all-time high, with pre-season testing adding to the theory fans should expect the unexpected.

Forecasting the year ahead is tricky, but Stats Perform seeks to identify the key narratives to follow this season ahead of Sunday's 2022 opener in Bahrain.

Max vs Lewis again

For now at least, Verstappen and Hamilton will expect to be the title frontrunners, which should mean another classic campaign.

Verstappen had never even led the standings until winning last year's Monaco Grand Prix, the first of five consecutive Red Bull wins – including four for the Dutchman.

That sequence ended at Silverstone, where contact with Hamilton sent Verstappen into the wall and set the tone for the rest of a frantic season, in which the pair repeatedly went at one another, crashing at Monza.

A titanic back-and-forth deserved a better ending than to be decided by a contentious call from race director Michael Masi in Abu Dhabi.

Now, defending champion Verstappen can attempt to prove he is better than Hamilton regardless of that decision, while the Mercedes man seeks to show his class once again as he pursues a record eighth title.

The midfield challenge

The game-changing 2022 regulations sought to enforce "closer racing", meaning both Verstappen and Hamilton could come under threat rather than simply blowing away the competition.

Early signs are encouraging on that front, with the two title rivals name-checking Ferrari's superb pre-season showing in the past week.

A resurgent Scuderia represent an obvious danger to those two, but so too do McLaren, Ferrari's midfield neighbours in recent seasons.

Lando Norris had four podiums last season before tailing off to finish sixth in the drivers' championship – still two places ahead of team-mate Daniel Ricciardo, who endured a tough first year with the team despite a famous win at Monza.

Having been aided by changes to the car for 2022, it is up to Ferrari and McLaren to close the gap considerably to Red Bull and Mercedes.

George a genuine threat?

Of course, Verstappen and Hamilton might typically expect their biggest challenges to come from those in the same cars.

However, Sergio Perez played the role of supporting Red Bull team-mate brilliantly in some key moments last year, while Valtteri Bottas continued to do his own thing without worrying Hamilton.

How a change in the Mercedes garage alters things remains to be seen. Bottas has been replaced by George Russell, who will hope to quickly make his mark.

Russell deputised for Hamilton for a single race the year before last and impressed, so it will be interesting to see if he now intends to push his legendary colleague all the way or will initially settle instead for helping his title bid.

Impact of refereeing reform

It is not only the cars that have had a makeover this year, with the officiating structure reorganised in the aftermath of the criticism aimed at Masi.

He is out as race director, with two men, Niels Wittich and Eduardo Freitas, taking his place, while other changes include the introduction of a "virtual race control room" to "assist the race director in the decision-making process".

Whether these changes suitably appease the team principals, who grew increasingly furious with each controversy last year, remains to be seen.

All parties would agree they would rather see the championship decided on the track – but it is not always as straightforward as that.

Following an eventful, dramatic and – dare we say it – the best Formula One season to date, the 2022 campaign has plenty to live up to.

Lewis Hamilton is going in search of a record eighth world title at the second time of asking after missing out to Max Verstappen on the final lap of the final race in 2021.

Reigning champion Verstappen is himself seeking some personal history this coming campaign, which begins with the Bahrain Grand Prix this weekend.

Ahead of what will hopefully be an equally as gripping season this time around, Stats Perform picks out some of the key numbers.

Hamilton narrowly missed out on surpassing Michael Schumacher as F1's most successful driver, though he has not missed out on top spot in successive years since joining Mercedes in 2013.

Should he match his achievement from last year, Red Bull's Verstappen (25 years, two months) would surpass Fernandes Alonso (25y, 2m, 23 days) as the second-youngest multiple world champion, behind only Sebastian Vettel (24y, 3m).

Mercedes may have suffered disappointment last time out, but they still finished top of the constructors' standings for a record-extending eighth time in a row. They are one short of equalling Williams as the second-most successful team, though Ferrari (16) are still well out in front.

In terms of other team milestones, Bahrain will be the 250th GP Mercedes have competed in, while they are six fastest laps away from setting 100. McLaren, meanwhile, are seven podiums from reaching 500 in F1.

Joining Hamilton at Mercedes this season is compatriot George Russell, who along with McLaren's Lando Norris is aiming to become the first Briton other than Hamilton to win a race since Jenson Button in 2012.

Bottas is now at Alfa Romeo and is joined by Guanyu Zhou, who will be China's first ever representative on the grid, making them the 39th country to appear in F1. Indeed, it is the first time three Asian countries will be represented, with Alex Albon (Thailand) and Yuki Tsunoda (Japan) also featuring.

Now 14 years on from their most recent constructors' title, Ferrari will equal their worst-such streak – 15 years between 1984 and 1998 – if they again miss out this term.

Carlos Sainz is Ferrari's big hope and he has either matched or bettered his performance from the previous season – both in terms of points and position – over the past six years when racing for just one team.

While his title chances are slim at best, Fernando Alonso has the opportunity to become the driver with the biggest margin between F1 titles of all time, 16 years on from his most recent success. 

Twenty-two events are currently locked in the F1 calendar for this year, with Miami set to become the 77th different circuit used when it hosts its maiden GP in May. It will be the 11th different track used in the United States, which is the most of any country.

Roma head coach Jose Mourinho has sparked the build-up for Sunday's Derby della Capitale remarking Lazio are off "smoking cigarettes" while his side progressed in the Conference League on Thursday.

The Giallorossi edged past Dutch outfit Vitesse after Tammy Abraham's 90th-minute goal earned a 1-1 draw and 2-1 aggregate victory.

Mourinho said Roma would quickly switch their attention to Sunday's derby with his side in seventh, one point behind Maurizio Sarri's Lazio in fifth.

"Obviously, I am not happy that we played today with many players who will also have to be there on Sunday while tonight Lazio are home smoking cigarettes with Sarri, but it’s because Vitesse are really good," Mourinho told reporters after the game.

Mourinho fielded a strong Roma outfit against Vitesse and given the situation of the tie, with Maximilian Wittek's 62nd-minute goal levelling it on aggregate, he was unable to rest any key players with a quick turnaround for Sunday's derby.

"Now Sarri is at home smoking his cigarette while I go home trying to think how we can recover from this for Sunday," Mourinho said.

He added: "We never came into this to control the result or aim for a draw to get us through. We worked with one objective, preparing to go for victory.

"It was a bad performance on a technical level, it might seem tactical, but it was technical. We defended well and showed character, but we also pushed hard at the end with El Shaarawy as a third striker, not a wing-back.

"I don’t want to say we 100 per cent deserved to go through, but over the two legs did a little more."
