Graham Potter promised Chelsea are doing what they can to get to the bottom of their injury issues.

Chelsea lost a third successive game on Thursday as they went down 2-1 to Fulham in a west London derby.

Compounding their issues at Craven Cottage, where debutant Joao Felix was sent off, midfielder Denis Zakaria suffered a quad injury.

It means Zakaria joins Raheem Sterling, Christian Pulisic, Edouard Mendy, Armando Broja, Ruben Loftus-Cheek, N'Golo Kante, Reece James, Ben Chilwell and Wesley Fofana on the sidelines.

Ahead of Sunday's clash with Crystal Palace, Potter – who has seen his side lose seven of their last 10 matches – knows Chelsea must find a solution.

"We're looking all the time, going over how it's happening," said Potter, who replaced Thomas Tuchel in September.

"Sometimes when you come in through the season it's difficult to know how it's happened. It's a bit of bad luck and also learning for us all how we can improve.

"The nature [of the injuries], it's not even a pattern, it's different problems. It's tricky.

"It's not like we’ve been over-training or anything like that. We certainly need to get to the bottom of it though."

Joao Felix's three-match suspension, meanwhile, has dealt another blow.

"Of course, disappointing because he came here to play, he's on loan to play," Potter said.

"You saw his quality when he was on the pitch and to lose him for the three games is a real blow for us. Nothing we can do now, we've just got to deal with it."

Chelsea are rooted in 10th place in the Premier League, and Palace would move level on points with the Blues should they win.

Potter has never won a home game against Palace across his managerial career, drawing one and losing three of four previous such games in charge of Swansea City and Brighton and Hove Albion, though Chelsea did beat the Eagles 2-1 at Selhurst Park under his stewardship earlier this season.

Chelsea have won their last 10 league games against Palace but have lost two of their last three top-flight matches at Stamford Bridge, and Potter knows his team need to get back to their best.

"We have to recover from the disappointment of the [Fulham] game, assess all the players and then we have to try to be positive, take a home game on, another London derby against a team with dangerous players, so we have to be good ourselves," he said.

Potter, meanwhile, confirmed there is no chance that Pulisic, who is set to be out until March due to a knee injury, will leave the club in January.

"No chance," he said. "There's never been any consideration about that anyway but he's a couple of months out.

"He's disappointed, optimistic he can come back quicker than the two months, so it's at that stage where it's fingers crossed for his rehab."

Arsenal made it a clean sweep of the Premier League's monthly awards for November and December as captain Martin Odegaard and head coach Mikel Arteta took home the prizes.

Odegaard was voted the league's standout player either side of the World Cup, across the first couple of weeks of November and the final six days of December.

Over that period, the 24-year-old was involved in six goals, split evenly between those he assisted and netted himself.

No Premier League player had a hand in more goals in that time, with Odegaard's form seeing him become the first Arsenal man to be named Player of the Month since Pierre-Emerick Aubameyang in September 2019.

His form helped the Gunners open a seven-point lead at the Premier League's summit heading into 2023, and he held off competition from compatriot Erling Haaland, Arsenal team-mate Bukayo Saka, Manchester United pair Casemiro and Marcus Rashford, plus Ben Mee, Joao Palhinha and Kieran Trippier.

Odegaard's boss, Arteta, was unsurprisingly the recipient of the Manager of the Month prize.

During the qualifying period, Arsenal won all four of their league matches to stretch their lead at the top.

It is the second time this season Arteta has won the award, having also claimed it in August, and the fourth time in total since taken over the Gunners in December 2019.

The Basque coach topped a shortlist that also included Brentford's Thomas Frank, Newcastle United boss Eddie Howe, and Jurgen Klopp of Liverpool.

Jurgen Klopp has ruled out a transfer raid to lift Liverpool for a push towards the Champions League places.

The Reds manager became riled by questions on the subject when speaking at his pre-match press conference on Friday, ahead of the trip to Brighton and Hove Albion.

Luis Diaz, Roberto Firmino and Diogo Jota are sidelined by injury, reducing Klopp's options in attack, and Darwin Nunez could also miss the Brighton game.

Key defender Virgil van Dijk is also out of action, but Klopp dismissed the idea Liverpool could use the January transfer window to solve their problems.

"I don't think so," he said. "My job is to use the boys we have, so that's it. I like the teams we line up, but when we start to change things you see we don't have three, four, five options, and if we have options they are pretty young.

"You cannot solve all problems in a transfer window. In a dreamland you would just buy players now and bring them in, but I don't see that coming."

Liverpool have been linked with the likes of Benfica's Argentina World Cup star Enzo Fernandez, but judging by Klopp's tone there will be no deal materialising there in the near future.

Asked why Liverpool would not be targeting the market for new additions, Klopp said: "What could be the reason? That we have money like crazy, but we don't buy the players even when they are available?

"That's what you think of me after all the years? Why ask the question when the answer lies on the table? I really don't understand that.

"If I sat here and said we have money in the bank, massively, like we don't know what to do with, but the players are out there but nah, we don't do that...

"We have on top of that the problem that in the moment four of our offensive players are injured, strikers.

"So if we buy another one and they come back, and we have seven strikers, we couldn't even put them all on the Champions League list. We'd have to make a decision.

"So it's just not that easy, you cannot solve the problem, especially with injuries.

"Injuries, that's the main, big, big shadow over all of us, because you cannot solve it in the transfer window. Sometimes you have to, but usually you have to get through until the boys come back and then you can use them again.

"The transfer market is for us not in this moment a solution. But if something's out there and someone tells me we can do it, we will do it, but in this specific situation I don't think it will happen."

Liverpool were held 3-3 by Brighton at Anfield in October, in a game that saw Leandro Trossard hit a hat-trick for the Seagulls.

That was early in the reign of Roberto De Zerbi, who replaced Graham Potter as Brighton head coach, and the south-coast club won none of their first five Premier League games under the Italian (D2 L3).

They have won four of their last six under De Zerbi, however, while Liverpool have lost three of their last seven in the league, as many as in their previous 37 games combined (W26 D8).

Klopp's side sit seventh in the table entering the latest round of games, seven points behind fourth-placed Manchester United.

A defeat last Monday to Brentford was a jolt for the Reds, who have not begun a calendar year with two league losses in a row since 1993, in the inaugural Premier League campaign, when they were beaten by Aston Villa and Wimbledon.

Klopp said of the trip to the Amex Stadium: "It will be a tough one, but I'm really looking forward to it because we've had a good week [in training] and I hope the players who are available during the week will stay available and be ready for a fight."

Manchester City will attempt to celebrate a landmark game for Pep Guardiola by securing a fourth consecutive win over Manchester United at Old Trafford on Saturday.

The eagerly awaited derby will be Guardiola's 500th match as a top-flight manager in an incredible trophy-laden career.

Of more importance for the City boss will be claiming a victory that would leave the champions only two points behind Premier League leaders Arsenal, who face a derby of their own at Tottenham on Sunday.

The Red Devils were hammered 6-3 when the two sides met at the Etihad Stadium in October, with Guardiola's men having done the double over their fierce rivals last season.

Fourth-placed United are flying under Erik ten Hag, though, and a win over City – who suffered a shock EFL Cup defeat to Southampton on Wednesday – would leave them only a point behind their neighbours.

Stats Perform has used Opta data to preview a huge derby showdown.

Another huge milestone for Pep

Guardiola has long since established himself as one of the best managers in the world, achieving great success with Barcelona, Bayern Munich and City.

He took charge of 152 LaLiga games during his Barca tenure, 102 in the Bundesliga with dominant Bayern and this will be his 246th Premier League match as City boss.

Guardiola has won 379 of the 499 top-flight encounters he has overseen, suffered 52 defeats and drawn 68 games. 

With a win percentage rate of 76, he has the most victories and highest win rate - for managers who have taken charge of at least 100 games - of any boss in Europe's big-five leagues since his first top-flight season in 2008-09.

United on a roll

Ten Hag has lifted the gloom and there is more of an air of optimism at Old Trafford, with United having won eight consecutive games in all competitions.

Since and including their win over Liverpool on August 22, no team has earned more Premier League points than United's tally of 35, winning 11 of their 15 games during that time.

The Red Devils have won all three Premier League games since the World Cup without conceding a goal and reached the EFL Cup semi-finals with a 3-0 win over Charlton Athletic on Tuesday.

City to add insult to injury by breaking scoring record?

Erling Haaland and Phil Foden scored hat-tricks as City put United to the sword just over three months ago.

Guardiola's men could break their record for the number of goals scored against United in a season, which stands at eight established by 5-0 and 3-2 victories way back in the 1954-55 campaign.

The most goals the Red Devils have conceded against an opponent in a Premier League season is nine against Liverpool in 2021-22.

Rashford can do no wrong

Marcus Rashford can do no wrong at the minute, scoring in every game since the World Cup.

He came off the bench to help himself to a late double in the win over Charlton, making it seven goals in six matches since returning from England duty in Qatar.

Rashford, who found the back of the net twice for the Three Lions in the World Cup, has scored 15 times this season for United – who are certainly not missing Cristiano Ronaldo.

Chelsea have welcomed the Football Association's (FA) decision to class the 'rent boy' chant often directed at their supporters as a breach of the governing body's regulations.

The chant has been heard at Chelsea fixtures down the years, sung by opposition fans, but has been strongly condemned for its homophobic nature.

The Crown Prosecution Service (CPS) has classed the chant as a hate crime, and the FA has stipulated that the singing of the chant could now result in disciplinary action for clubs.

In a statement released on Friday, Chelsea said: "The 'rent boy' chant is intolerable and has no place in football or anywhere else.

"That opposition clubs can now face disciplinary action if their supporters engage in this discriminatory and offensive behaviour is a step in the right direction.

"Everyone who chooses to participate in this chant must know their actions have consequences.

"Alongside our No To Hate campaign, we will continue to work with the FA, the CPS, opposition clubs, and our own LGBTQI+ supporter group Chelsea Pride in the pursuit of positive change.

"There is plenty more work to be done, but we won't rest until football is a game where everyone feels welcome."

Arsenal should be labelled as favourites in the north London derby, but Harry Redknapp says Harry Kane will always give his old team Tottenham a fighting chance.

Premier League leaders Arsenal make the short trip across the capital to face their rivals on Sunday.

A 3-0 defeat to Antonio Conte's team in the corresponding fixture last season was the start of Arsenal's capitulation in the run-in, which saw them miss out on the Champions League.

Yet Mikel Arteta's side are flying high this term and, having beat Spurs 3-1 in October, Arsenal are looking to complete their first league double over their rivals since 2013-14, which was also their last league victory away at Tottenham.

Former Spurs manager Redknapp believes Arsenal have the edge, but is confident Kane – the highest-scoring player in north London derby history with 14 goals – will take an opportunity if it comes his way.

"At the moment, you'd have to fancy Arsenal, to be honest, they look so good," Redknapp told Stats Perform.

"They're so full of confidence. I love the way they're playing. I think they've got some real quality players, but when you've got Harry Kane in your team, you've always got a chance, you've got a puncher's chance.

"They might get outplayed for long periods of a game but Kane can land a knockout blow anytime. So I wouldn't write Tottenham off by any means. I think it'll be a tight game."

Kane has scored in all but one of his eight league home games against Arsenal, only failing to find the net in a July 2020 clash, when the competition restarted behind closed doors during the coronavirus pandemic.

The 29-year-old has scored 198 Premier League goals and is just one strike away from matching Jimmy Greaves' record of 266 goals for Tottenham.

Only Erling Haaland (21) has scored more Premier League goals than Kane (15) this season, with the Spurs talisman having far over performed his expected goals of 10.5.

Wayne Rooney (208) and Alan Shearer (260) are the only players to have scored more Premier League goals than Kane, who Redknapp believes is the cream of the crop.

"Oh without a doubt, yeah," Redknapp said when asked if Kane will break the competition's goalscoring record.

"I think he'll smash it to pieces. Harry's just an amazing player, he's the best centre forward in the world in my opinion.

"He's right up there isn't he? Shearer you know how far do you go back you know, but you know, he's up there with the very, very best isn't he?

"The great Jimmy Greaves was a different type of player, Jimmy was a fantastic footballer. Genius. But Harry is just amazing. For me, he's the best all-round centre forward, he can do everything. The complete player.

"There's nothing he doesn't do. Team player. Great guy, not a problem. Perfect professional."

Eddie Howe will support a "remorseful" Joelinton after a drink-driving charge, but the Newcastle United boss has not yet decided whether to drop the midfielder this weekend.

Joelinton starred in Newcastle's 2-0 EFL Cup quarter-final win against Leicester City on Tuesday, scoring one goal and creating the other for Dan Burn.

However, the Brazilian was arrested in the early hours of Thursday morning for being over the prescribed limit for alcohol at the wheel of a vehicle.

Joelinton will appear in court on January 26, between the two legs of Newcastle's cup tie against Southampton – the Magpies' first major semi-final since 2005.

The incident has marred what had been a great week for Newcastle, with a huge Premier League clash with Fulham to come on Sunday.

Newcastle enter the weekend in third place, with Fulham in sixth, but head coach Howe told reporters on Friday he had yet to decide what Joelinton's role would be in the match.

No player has made more appearances (47) or starts (45) or played more minutes (3,845) for Newcastle in all competitions since Howe's November 2021 appointment.

Howe added: "It came very much as a shock. Joe was very upset and remorseful yesterday.

"He knows the seriousness of the situation, and so do we as a club. I think he understands his responsibilities, and we are now supporting him.

"We will deal with the matter internally. From day one, he's been a very good professional and hugely passionate about his career and the club.

"I was very surprised about what happened. We will back him and support him but also educate him about what happened. Everyone makes mistakes."

Joelinton has turned his career around under Howe, with only three players topping his nine goal involvements in the coach's tenure.

He has played a key role in Newcastle's 13-match unbeaten Premier League streak; a 14th game without defeat against Fulham would tie the club's record run in the competition.

With or without Joelinton, Fulham represent a tough test, despite losing the reverse fixture 4-1 at Craven Cottage – a rare match in which Newcastle's number seven was left on the bench.

Marco Silva's side could even close to within a point of Champions League-chasing Newcastle with a win, but the Fulham boss said of a top-four challenge: "We are in a great position in the table, but we are not going to change anything from our goals until we achieve that.

"It is clear for me the goal is still at the same level. No one in our football club will achieve the goals until we achieve it. Until we remain in the Premier League, we are not changing anything from our aims and our ambitions.

"We are an ambitious football club, definitely, and I'm ambitious as a manager; my players, too. But we have to be realistic. We are really pleased how we have been playing, how we have achieved great results for us, but the Premier League is really tough."

Arsenal's interest in Shakhtar Donetsk midfielder Mykhaylo Mudryk is well known, having pursued him in the last transfer window.

The 22-year-old Ukraine winger has scored 10 goals in 18 appearances for Shakhtar this term, enhancing his value.

Mudryk has also had interest from Sevilla and Chelsea, with the Gunners having reportedly previously made two bids for his services.

TOP STORY - GUNNERS CLOSE IN ON AGREEMENT FOR MUDRYK DEAL

Arsenal have tabled a fresh third bid worth €70m (£62m) plus add-ons for key target Mykhaylo Mudryk of Shakhtar Donetsk, claims Fabrizio Romano.

Talks are ongoing with no breakthrough but the two parties are getting closer to agreement, while Mudryk posted a praying emoji on Instagram in a sign he wants to make the move.

The Daily Express claims that the two clubs have come to an agreement on the fee, with negotiations entering the "final stage".

ROUND-UP

- Al Hilal, rivals of Cristiano Ronaldo's new Saudi Arabian club Al Nassr, are plotting a €275m move for World Cup winner Lionel Messi from Paris Saint-Germain, reports Mundo Deportivo. The Sun has reported Messi's father Jorge has been spotted in Saudi Arabia too.

- Arsenal are also again interested in Juventus forward Dusan Vlahovic, reports La Repubblica. According to the report, the Serbian is valued at €110m (£97.7m).

- Sport claims that Newcastle United have tabled an offer for Barcelona's Dutch forward Memphis Depay.

- PSG are set to offer Milan Skriniar a €12m-a-year contract, provided he agrees to leave Inter on a free transfer, reports La Repubblica. Skriniar's Inter deal concludes at the end of this season.

- AS reports that PSG have accepted a bid for Wolves for 30-year-old Spanish midfielder Pablo Sarabia.

- Besiktas are turning to Wolves' forward Raul Jimenez to replace Manchester United-bound Wout Weghorst, according to Fotospor.

After a week's break for the FA Cup, the Premier League is back with a full round of fixtures this weekend – in fact, some teams have midweek games too.

As such, fantasy football managers turn their attention back to team selections, transfers and captain choices.

Using Opta data, Stats Perform has picked out four options that might be worth your consideration…

Dean Henderson (Nottingham Forest v Leicester City)

Forest endured a pretty brutal reality check upon their long-awaited return to the Premier League, but things have started looking up in the past few weeks.

Henderson has undoubtedly been a shrewd addition between the posts and his recent form reflects Forest's general improvement.

Four of his five Premier League clean sheets this term have come in his seven most recent appearances, while Forest have collectively restricted their opponents to two or fewer shots on target in four of their past five outings.

Sven Botman (Newcastle United v Fulham)

Newcastle have excelled in many areas this term, hence their position in the top four. Defensively they have been solid, and Botman has more than played his part.

Eddie Howe's men have kept a clean sheet in each of their past four league games, with Botman playing at least 87 minutes in all of them.

Only four players have contributed to more clean sheets than his seven this season, and another will see the Magpies record five successive top-flight shutouts for the first time.

Bruno Fernandes (Manchester United v Manchester City)

Granted, Fernandes is not exactly an "out there" selection, so this is more of a reminder of the value he can represent.

For starters, he is in good form having provided an assist in each of his past two league games, and for the season only Kevin De Bruyne (41) has created more chances in open play (40).

While he only has three assists, his 4.3 expected assists is the third best in the division, suggesting his team-mates have not fully made the most of his craft.

But with Marcus Rashford in such form and a big game against City – following by a midweek trip to struggling Crystal Palace – up next, Fernandes will be a leading candidate to be decisive.

Evan Ferguson (Brighton and Hove Albion v Liverpool)

From a slightly obvious pick to a real wildcard, but bear with us.

Ferguson has made a big impact at Brighton over the past few weeks. The 18-year-old has been involved in three goals across his past two games (two goals, one assist).

If he gets another goal against Liverpool at the weekend, he will be the youngest player (18 years and 87 days on Saturday) to score in three consecutive Premier League games since Michael Owen (18y, 12d).

Is it written in the stars?

Erik ten Hag's arrival at Manchester United last year began a process of culture reset. For years, the club allowed big egos to inflate, and the team's mentality to shrink, while an arrogant hierarchy seemingly assumed waving big cheques guaranteed success.

Ten Hag has taken steps to fix all of the above, and in the roughly eight months since he began working in May, the difference has been significant.

"There was no spirit," Ten Hag said last week. "I saw no team dynamic in the squad. The mental resilience was very low. I saw that as an outsider – and also noticed it in my first weeks at the club.

"I looked at the culture of the club. I asked, 'how did Manchester United become great?'. The club has bought an unimaginable number of players in recent years who have not been good enough. Most purchases have been average – and at United average is not good enough. United's shirt weighs heavily."

Of course, hindsight is 20/20, and you can't say Ten Hag's impact has come without "waving big cheques". But the problem with previous eras was how the money was spent.

Casemiro, who cost £60million, is the prime example. At 30 years old, there's no doubt some fans were unsure he was the man to reinvigorate a midfield that had quite literally been a problem for over a decade, but he's been exceptional and a big part of United's transformation.

From slow start to key man

Saturday's Manchester derby will be a true litmus test of not only United's progress under Ten Hag, but also the influence Casemiro has.

Let's not forget, City crushed United 6-3 at the start of October. Pep Guardiola's men were even 6-1 up for about 11 minutes before a late Anthony Martial double.

Their midfield of Scott McTominay, Christian Eriksen and Bruno Fernandes simply couldn't handle City's dynamism, and then Erling Haaland and Phil Foden were irresistible in front of goal.

That was, unsurprisingly, the last game before Casemiro took ownership of the holding midfield role at United. Casemiro has played 1,330 minutes across all competitions since, second only to Fernandes (1,349), while Scott McTominay has managed just 439.

Over the same period, only Newcastle United (24) have claimed more points than the Red Devils (23) in the Premier League, with November's 3-1 reverse at Aston Villa their sole defeat.

Of course, it's difficult to attribute United's improvement to Casemiro alone, but there's no doubt his effective blend of destructiveness and creative subtlety have made Ten Hag's midfield a completely different proposition.

Not only is he so adept at reading the game and snuffing out attacks, Casemiro's long-underrated technical abilities suit Ten Hag's style of play down to the ground.

More than meets the eye

Anyone who regularly watched Real Madrid during Casemiro's long stay will have already known there's more to him than simply kicking people. Admittedly, frequent viewers of arguably the most popular team on Earth is hardly a niche group, yet there was certainly a lack of awareness from fans and pundits alike regarding Casemiro's 'other' talents when he joined United.

Because Ten Hag wants his team to generally dictate possession, players without excellent technique will stick out like a sore thumb, which is presumably one explanation for Aaron Wan-Bissaka featuring so irregularly until the past couple of weeks.

The fact Casemiro has become so influential speaks volumes.

Every 90 minutes he averages 6.3 involvements in open-play passing sequences that end in a shot, a record bettered by only five central midfielders in the Premier League this term (min. 500 minutes), including more recognised creators like Fernandes (7.3) and Kevin De Bruyne (8.0).

Additionally, just five players in the entire league (min. 500 minutes) have been involved in more shot-ending build-up sequences (48) without creating or taking the shot. Both of these highlight how central Casemiro's playmaking skills are from his deeper role, even if he's not necessarily the one playing the key pass.

But he is proving extremely effective without the ball as well, and his powers of ball recovery combined with smart distribution make him such an asset, with only Rodri (32, from 1,391 minutes played) initiating more shot-ending open-play sequences after winning possession than Casemiro (22, from 979 minutes played).

It's arguably that hard-working, destructive nature that makes him so refreshing for United, though. The only other central midfielder they've had over the past 15 years who has recorded at least three tackles and eight duel wins (3.8 and 8.1) on a 90-minute basis over a season is Marouane Fellaini in 2013-14 (3.1 and 9.3) and 2016-17 (3.0 and 10.8).

Fellaini's stats will be boosted by his aerial effectiveness, and obviously the Belgian never had the same technical grasp Casemiro has, with his two brilliant passes in the build up to Marcus Rashford's goals in the EFL Cup win over Charlton Athletic earlier this week prime examples of his class in that respect.

He's probably the most complete midfielder they've had since Roy Keane, and the fact Ten Hag so emphatically filled a void that's been gaping throughout the post-Alex Ferguson era is proof enough of the manager's culture shift at Old Trafford.

Beating City will be another major statement.

Hearts manager Robbie Neilson accepts Socceroos forward Garang Kuol is not the "finished article" but is thrilled to land the 18-year-old on loan from Newcastle United.

The Edinburgh club confirmed the temporary signing – subject to international clearance – of Kuol from the Premier League side on Thursday, reportedly beating several Championship clubs to him.

Kuol impressed with two cameos for Australia at the 2022 World Cup, where the Socceroos reached the round of 16 for the second time.

In September, the teenager agreed a pre-contract deal to join Newcastle in January from A-League club Central Coast Mariners, with the Magpies eager to loan him out for first-team experience.

The Egypt-born talent only debuted for Central Coast in December 2021 and made just 22 first-team appearances – netting seven goals – before joining Newcastle.

"It's fantastic news that Garang has committed himself to Hearts for the next six months," Neilson said.

"It's no secret that we were extremely interested in him and he came up for a look around last week. He was impressed with what he saw and what we're trying to do here, which is pleasing.

"We're getting a player who is by no means the finished article but there is a lot of talent there – you don't get called up to and play in the World Cup for nothing.

"He'll offer us new options going forward as we look to continue our good form and continue to make progress in the league and in the Scottish Cup, and we're really looking forward to working with him."

Kuol joins fellow Australians Kye Rowles, Cammy Devlin and Nathaniel Atkinson at Hearts. All four were part of the Socceroos' World Cup squad.

"The gaffer also persuaded me to come here with the plan that he put to me for my development," Kuol said.

"Overall, the club has great ambitions and goals, and that was something I wanted to be involved in. I think it was a very good decision."

Hearts are third in the Scottish Premiership with 32 points from 20 games, 26 points behind leaders Celtic.

Graham Potter says Joao Felix's red card was the turning point in Chelsea's 2-1 defeat to Fulham, but the under-fire Blues boss understands why the debutant was dismissed.

Chelsea had levelled Thursday's contest at Craven Cottage when Joao Felix was sent off by referee David Coote for a studs-up challenge on Kenny Tete.

Carlos Vinicius went on to head home a winner for Fulham as they beat their west London rivals for only the fourth time in 53 top-flight matches, and the first time since 2006.

Potter was left to rue a sloppy challenge from Joao Felix, who was thrust straight into the starting XI after arriving on a short-term loan deal from Atletico Madrid on Wednesday.

He is the first Chelsea player to be sent off on his Premier League debut, and the first for any club since Federico Fazio for Tottenham against Manchester City in October 2014.

"It was a forwards' tackle. There was no malice in it but I understand why it was a red," Potter told BT Sport of the Portugal international's lunge on Tete.

"It is another blow for us; the hits keep coming at the moment. [Joao Felix] was really good. You could see his quality in the game so it is doubly disappointing for us."

Willian had given Fulham the lead against his former side Chelsea, but the visitors responded through Kalidou Koulibaly's close-range finish after Mason Mount had hit the post.

Carlos Vinicius' first goal for Fulham prolongs 10th-placed Chelsea's terrible run of form, which now stands at seven defeats in 10 matches in all competitions.

"I think we controlled the game early, won the ball back high, created some opportunities, maybe missed the last pass. We made a couple of mistakes for their goal," Potter said.

"Second-half I think we responded well and then the red card changes the game. It makes it a little more difficult for us.

"But I thought the application when we went down to 10 was really good. I'm disappointed with the [winning] goal because I think we could do better and that is what cost us."

Chelsea's return of 25 points from their first 18 Premier League matches is their fewest at this stage since the 2015-16 campaign (18 points), when going on to finish 10th.

Further questions will inevitably be asked of Potter, who only succeeded Thomas Tuchel in September, but the Englishman has called on his squad to stick together.

"We have got to keep working, there is no other solutions," he said. "You have to keep working stay together and try to get the three points."

Former Chelsea winger Willian did not celebrate his first-half opener against old suitors Chelsea, whom he won five major honours with earlier in his career.

"I had an amazing seven years at Chelsea," said Willian, who is the 26th player to score against Chelsea in the Premier League after previously playing for them.

"I have a big respect for the fans and the club. I play for Fulham now and have to do my best. It was a special night.

"We deserved the win. We know how difficult it is to play against Chelsea. They are in a difficult moment but we are a really good team. We deserved it and we have to carry on."

A fourth top-flight win in a row for Fulham – the first time they have achieved that since April 1966 (a run of five) – moves them within four points of the Champions League spots.

Debutant Joao Felix's red card proved costly as Carlos Vinicius earned Fulham a 2-1 win over west London rivals Chelsea that piles even more pressure on head coach Graham Potter.

Joao Felix was named in injury-hit Chelsea's starting line-up, a day after joining on loan from Atletico Madrid, and saw red for a lunge on Kenny Tete shortly before the hour mark.

Chelsea had fought their way back into the match at the time of that dismissal after Kalidou Koulibaly's close-range finish cancelled out former Blues winger Willian's first-half opener at Craven Cottage.

Fulham were without suspended top scorer Aleksandar Mitrovic, but Carlos Vinicius headed in his first Fulham goal in the 73rd minute to land his side a rare win in this fixture and make it six defeats in eight for Chelsea.

Bernd Leno did well to keep out an early Lewis Hall strike in a bright start from Chelsea, with Joao Felix looking particularly lively in the final third.

Fulham soon grew into the game and struck the crossbar through a powerful Bobby Decordova-Reid effort, shortly after Carlos Vinicius had a penalty shout rejected.

However, Willian gave Fulham the lead when Chelsea's defence backed off and allowed the winger to fire away a shot that deflected off Trevoh Chalobah on its way through.

Leno continued to frustrate Chelsea, but he was almost caught out by a Mason Mount free-kick that struck the right-hand post and landed nicely for Koulibaly to squeeze over the line.

Chelsea lost another player to injury when Denis Zakaria hobbled off and then had Joao Felix dismissed for a studs-up challenge on Tete.

More misery was to follow for Chelsea and Potter as Andreas Pereira played in a delightful cross for Carlos Vinicius to get above Chalobah and power home a winning goal at the back post.

Joao Felix was thrown straight into the Chelsea starting XI for the Premier League clash at Fulham on Thursday.

The Portugal international sealed a loan move until the end of the season from Atletico Madrid on Wednesday and head coach Graham Potter wasted no time in handing him his first start.

Potter opted for Joao Felix in attack with Kai Havertz and Mason Mount for the match at Craven Cottage, making four changes from the team that was thrashed 4-0 by Manchester City in the FA Cup on Sunday.

The former Brighton and Hove Albion boss also brought in Thiago Silva, Cesar Azpilicueta and another loan signing in Denis Zakaria, leaving out Bashir Humphreys, Conor Gallagher, Jorginho and Hakim Ziyech.

Chelsea went into the local derby 10th in the Premier League, 10 points off the top four and three behind Fulham, albeit having played a game fewer.

Newcastle United midfielder Joelinton has been charged with drink-driving and will appear in court at the end of January.

The 26-year-old was pulled over by police in the early hours of Thursday morning and subsequently arrested for being over the prescribed limit for alcohol.

A Northumbria Police spokesperson said: "Shortly before 01:20am today, officers pulled over a vehicle in the Ponteland Road area of Newcastle and arrested the occupant.

"Joelinton Cassio, 26, of Ponteland, has since been charged with driving whilst above the prescribed limit for alcohol."

Joelinton will appear before magistrates in Newcastle on January 26, which is sandwiched between the two legs of United's EFL Cup semi-final with Southampton.

The Brazilian has played in 21 of Newcastle's 23 games this season, starting 19 of those – only five players have featured more times.
