Brighton have rejected a second bid from Chelsea for star midfielder Moises Caicedo.

The Blues’ latest offer for the Ecuador international is believed to be around £70million.

Caicedo requested to leave Albion in January amid interest from Arsenal but in March signed a new contract until 2027.

The 21-year-old, who last season helped the Seagulls qualify for Europe for the first time and reach the semi-finals of the FA Cup, remains of interest to a number of Premier League rivals.

Caicedo joined Brighton from Ecuadorian club Independiente del Valle for a reported £4.5m in February 2021 before being loaned to Belgian side Beerschot.

He made his top-flight debut in April 2022 and has played 53 times during his time at the Amex Stadium, scoring two goals.

Chelsea and Brighton are scheduled to meet on Saturday in Philadelphia in a six-team Premier League pre-season tournament.

New Blues manager Mauricio Pochettino is in the process of overhauling his squad following the club’s worst season in almost 30 years.

Forwards Christopher Nkunku and Nicolas Jackson have already arrived at Stamford Bridge this summer, while Mason Mount, Kai Havertz and Mateo Kovacic are among a host of departures.

Bethany England says she stayed longer than she should have at Chelsea feeling “wasted” as the striker looks to take her fine form for Tottenham into the World Cup.

After an impressive 2019-20 campaign with the Blues which saw her named PFA player of the year, the 29-year-old subsequently found herself in and out of their starting line-up, and was part of it only twice in the first half of the 2022-23 Women’s Super League season.

She subsequently made a January move to Tottenham, went on to score 12 goals in as many league starts and earned an England recall – her first involvement since last September – when boss Sarina Wiegman named her squad in May for this summer’s World Cup in Australia and New Zealand.

England said: “They (Chelsea) brought Sam Kerr in halfway through the (2019-20) season and I built up a great relationship playing with Sam, and then obviously it didn’t transpire to the next season where we didn’t play with a front two.

“Emma (Hayes, the Chelsea manager) opted for singular number nine, which made my chances much more difficult based off Sam being who she is – and she is a prolific goalscorer.

“So it was hard to kind of fight my way back in from that point and I think I probably overstayed maybe a year, a year-and-a-half too long, where I felt like I was just wasted there, and I wasn’t being used enough.

“It was a very difficult time, but I think I built up a lot of resilience from that and was able to take that into other scenarios in football.”

England, who joined Chelsea in 2016 and scored a total of 74 goals for them, added: “I think there was ultimately lots of reasons why I left, the World Cup being one of them.

“I think the move has paid off for me and, as you would say, (it has been) vindicated. Ultimately, I think if I had stayed where I was, sat on the bench, I would never be here today.”

England’s wait for an international recall initially went on after the January transfer despite her hitting goals for Spurs from the off, and she said: “I didn’t get selected for the (February) Arnold Clark Cup, and then I went and scored against Manchester United (running with the ball) from the halfway line.

“I think that was my ‘have some of that’ type thing. It was more like: ‘Look, I know I am good enough’.

“But equally, I had to balance not focusing too much on what was going on (with England), because ultimately if I didn’t do the job at club level, I wouldn’t have been here.”

Having continued to flourish with Tottenham, England, who was a member of Wiegman’s Euro 2022-winning squad as an unused substitute, is now among three main number nine options in the World Cup 23, along with Alessia Russo and Rachel Daly.

“I want to help the team and put the ball in the net, however they may go in,” said England, who has scored 11 goals in 21 international appearances.

“The biggest thing I would say is leading into the World Cup Sarina has been able to see me more, playing regularly, scoring goals.

“I am hoping, as a collective, everyone can see what qualities I can bring. They know I can bring that to this team and hopefully I am put in a position where I can help showcase that.

“I think me and Alessia are very different players. I would say I am more similar with Rachel. I think we are all great in our own way and whatever tactics suit the game at that time is going to showcase that.

“It’s a tough decision because we have all got different qualities, but whoever Sarina chooses to go for is her preference.”

England open their campaign by playing Haiti in Brisbane on Saturday.

Chelsea will get their Women’s Super League title defence under way with a clash against Tottenham at Stamford Bridge on October 1.

The 5.30pm kick-off between Emma Hayes’ champions and Spurs, in their first match under new head coach Robert Vilahamn, is one of three games on the 2023-24 season’s opening day that are set to take place at Premier League grounds.

Last term’s runners-up Manchester United play Aston Villa at Villa Park in the day’s earliest contest (12.30pm kick-off), and Arsenal face Liverpool at the Emirates Stadium.

Promoted Bristol City will begin their WSL return by taking on Leicester at Ashton Gate.

Tuesday’s fixtures announcement also revealed Manchester City are to go to West Ham and Everton host Brighton on the opening day.

Chelsea – who have lost their opener in each of the last two campaigns, and are bidding to secure a fifth successive title, and seventh overall – earlier this month announced the club were committed to holding four WSL games at Stamford Bridge during the 2023-24 season.

Arsenal had already confirmed they would be playing five at the Emirates, and after their match against Liverpool, the Gunners are scheduled to also play there in their next home fixture, against Villa on October 15.

The stadium is then set to host Jonas Eidevall’s side playing Chelsea on December 10, Manchester United on February 18 and Tottenham in a March 3 derby. Last September, Arsenal beat Spurs 4-0 there in front a WSL record crowd of 47,367.

The second round of fixtures on October 8 features Manchester City v Chelsea and Manchester United v Arsenal.

The ‘Women’s Football Weekend’ pencilled in for March 23-24 includes derbies of Manchester City hosting Manchester United and Everton entertaining Liverpool, while the concluding round of fixtures, on May 18, includes Chelsea playing United away.

The new top-flight season starts six weeks after the conclusion of the Women’s World Cup in Australia and New Zealand, the final of which takes place on August 20.

The Women’s Championship is set to begin on August 26 with Birmingham, who finished second last season, facing Blackburn at Ewood Park, while promoted Watford hosting Durham is among five fixtures taking place the next day.

France midfielder N’Golo Kante joined Chelsea from Premier League champions Leicester for a reported £32million, on this day in 2016.

Kante’s only season with the Foxes, following his arrival from Caen the previous summer, saw him play a pivotal role in their title-winning campaign.

He was offered a bumper new contract at the King Power Stadium but opted to leave for Chelsea.

“Despite the offer of a substantially-improved, long-term contract, it became apparent that N’Golo’s wish was to join Chelsea,” said a Leicester statement.

Kante cited the opportunity to work under then-Blues boss Antonio Conte as a major reason for moving to Stamford Bridge.

“I am so happy to have signed for one of the biggest clubs in Europe. It’s adream come true for me,” he said.

“The opportunity to work with a brilliant coach and some of the best players in the world was simply too good to turn down.”

Chelsea won the Premier League during Kante’s first season in London as the now 32-year-old became the first player since Eric Cantona in 1993 to win back-to-back top-flight titles in England with two clubs.

Kante also won the FA Cup, Europa League and Champions League before leaving Stamford Bridge this summer for Saudi Pro League side Al-Ittihad.

After their worst season in nearly 30 years, Chelsea have never had a more critical summer in terms of transfer business.

Departures are likely to prove as crucial as new signings and there has been plenty of movement in both directions, with expectation that more business will take place throughout the window.

The PA news agency looks at what has been done and what to expect ahead of Mauricio Pochettino’s first season in charge.

How urgent is it all?

Very. Chelsea have a bloated first-team squad following owner Todd Boehly’s scattergun first 12 months at the helm, with more than £600million spent on transfers.

Successive managers in Graham Potter and Frank Lampard admitted to finding the job of accommodating so many players an almost unworkable challenge, and since January there has been little consistency in team selection or shape.

There is also the matter of satisfying Financial Fair Play rules. With sky-high outgoings and no income from European football, something has to be done to balance the books.

Chelsea have so far confirmed the sale of nine players since the window opened last month.

Who’s on the way in?

Christopher Nkunku has joined from RB Leipzig for £53m after a pre-contract agreement was reached in January for the France international.

With the team having recorded their lowest goal tally in almost a century last campaign, Villarreal’s Nicolas Jackson has also been added to Pochettino’s attacking options.

Moises Caicedo of Brighton is a long-term target but no bid has been made since the Seagulls rebuffed Chelsea’s repeated overtures in January.

Pochettino is reported to have turned his attention to France Under-21 and Lyon winger Rayan Cherki as a replacement for Christian Pulisic.

Who has already left?

Chelsea have raised eyebrows with the amount of outgoings from Stamford Bridge in the last month, which has allowed Pochettino to streamline his bloated squad ahead of their pre-season tour to the US.

N’golo Kante accepted a reported £86m-a-year offer to become the latest star name to swap a major European club for Saudi Arabia.

Defender Kalidou Koulibaly was in and out of the team during his one season in blue and left for Al-Hilal less than 12 months after joining from Napoli.

Mason Mount’s contract saga came to an end when he penned a five-year deal with Manchester United in a move away from his boyhood side.

Edouard Mendy’s three years in west London came to an end when he made the move to Saudi side Al-Ahli after falling behind in the goalkeeper pecking order to Kepa Arrizabalaga.

Kai Havertz signed for Mikel Arteta’s Arsenal for a reported £65million, while Mateo Kovacic was picked up by Pep Guardiola’s treble-winning Manchester City on a permanent deal as a replacement for club captain Ilkay Gundogan.

Captain Cesar Azpilicueta also bid farewell to the club after 11 years of service, while Ruben Loftus-Cheek and Pulisic joined up with former teammates Fikayo Tomori and Olivier Giroud at AC Milan.

Who will be next?

Hakim Ziyech’s move to Al-Nassr fell through at the last minute and Chelsea will still be keen to shift the unwanted winger before the window closes.

Conor Gallagher has attracted interest from a number of potential suitors but the 23-year-old could be vital for Chelsea next season, with midfield options looking short after this summer’s fire sale.

Brighton could bid again for Levi Colwill after his stellar performances in England’s European Under-21 Championship campaign – the young centre-back is yet to commit to a long-term deal.

Who else is surplus to requirements?

Striker Romelu Lukaku is eager to return to Inter where he spent last season on loan, though Chelsea have reportedly been unwilling to agree to another temporary move as they seek a permanent transfer.

Pierre-Emerick Aubameyang is another outcast to have been linked with the Saudi Pro League and is unlikely to have a future at Stamford Bridge, though it is thought he remains unconvinced about a move to the Gulf.

Callum Hudson-Odoi and Chelsea could part ways this summer but there has been no concrete interest from potential clubs after the winger’s underwhelming loan spell at Bayer Leverkusen.

Christian Pulisic has joined the growing number of players to leave Chelsea this summer after completing a move to AC Milan.

The 24-year-old midfielder has signed a contract with the Serie A giants until June 30 2027, with an option to extend for a further year.

Pulisic spent four years at Stamford Bridge after joining from Borussia Dortmund in 2019, making 145 appearances and scoring 26 goals for the Blues.

One of those goals was in the 2021 Champions League semi-finals against Real Madrid, which helped Chelsea into the final where they beat Manchester City.

The United States international also won the European Super Cup and Club World Cup with Chelsea the following season.

Pulisic, who has made 60 appearances for his country and helped them reach the knockout stages of last year’s World Cup, will link back up with former Chelsea team-mate Ruben Loftus-Cheek, who joined Milan last month.

They are among a host of senior players to leave Stamford Bridge this summer as the club rebuilds under new boss Mauricio Pochettino, with the likes of Mason Mount, Kai Havertz, Cesar Azpilicueta, Mateo Kovacic and Kalidou Koulibaly also moving on.

Former Chelsea manager Frank Lampard has revealed he wanted to sign Declan Rice, believing the Arsenal-bound midfielder could have been the Blues’ long-term captain.

Former Chelsea academy player Rice, who has since gone on to establish himself as an England regular under Gareth Southgate, captained West Ham to Europa Conference League glory last month ahead of his expected move to north London.

Lampard, who managed Chelsea between 2019 and 2021 before returning for a stint as caretaker boss earlier this year, told the Diary of a CEO podcast: “I wanted to bring in Declan Rice.

“I was like ‘this kid is going to be the captain of Chelsea for the next 10 years’. It didn’t happen, anyway, it is hard to dissect people’s work.”

Lampard returned to the club as interim manager in April after Chelsea sacked Graham Potter but only managed one win in his 10 games in charge as the Blues finished 12th.

Chelsea’s record goalscorer referred to the troubles he experienced with the oversized squad he inherited after the £600million-plus investment from Todd Boehly’s Clearlake Capital consortium since 2022.

Lampard added: “The biggest thing about the low standards was the size of the squad. The motivation was tough with players outside the Champions League squad.

“When I came in, very quickly I noticed that some players were thinking about the season’s going to peter out and what the future’s going to look like and that was a difficult situation.

“When you have international players in a big number then of course you’re telling internationals to stay at home and it’s not easy, and to have the conversation with them every Friday and to get them lined up coming in is also not easy for your own energy.

“I think there’s an understanding at the club that (squad size) has to change now, I think it has to change and if you lack those basics then it’s really hard to get where you want to get to.”

Chelsea have since appointed Mauricio Pochettino as their new manager and have streamlined their bloated squad by selling eight first-team players ahead of their pre-season tour to the United States.

Lampard talked up Mason Mount, who is among those to have left Stamford Bridge this summer, signing for Manchester United earlier this month.

“I think it’s a great signing,” Lampard said.

“So in terms of what he’ll bring to Manchester United, it won’t just be what Mason brings, he will bring loads of talent, but he’s just going to go and (raise) the levels.”

Mauricio Pochettino would not be drawn on whether he would push for Chelsea to reunite him with England captain Harry Kane as he was formally unveiled as manager at Stamford Bridge.

The pair enjoyed success during their days together at Tottenham, reaching the Champions League final in 2019, and the Argentinian was pressed on whether he would look to Kane to try and revive his new side’s ailing attack.

Chelsea scored only 38 league goals last season, their worst return in almost a hundred years, as they finished a dismal 12th in the Premier League.

They have already added RB Leipzig forward Christopher Nkunku and Nicolas Jackson from Villarreal, and the manager said the club are still looking to do more business to improve their front line.

But he stopped short of saying he would ask the club to bid for Kane, who scored 30 times in the league last season and, with Spurs not qualifying for Europe, has been the subject of interest from Bayern Munich.

“You are talking about one of the greatest strikers in the world,” said Pochettino. “I think it’s too unfair to talk (about a player at another club). The most important thing is that fans are not stupid. They are so clever. They know my relationship with him was always amazing.

“I saw him when he was young and grow up and achieve all that he was achieving. We have a great relationship.

“At the moment, we are thinking (in the transfer market) in a different way. We are not thinking that. We’re working hard to try to provide the squad with good quality.

“We are working on that and still we have time to work. For sure we are going to add players that can score and we are going to find the best way to play.”

The club have begun a significant overhaul of their squad since the transfer window re-opened, with players leaving to slim down the squad and trim the wage bill.

Mason Mount and N’Golo Kante have led an exodus of nine first-team players to depart so far, but the club remain in the market for recruits as they look to address last season’s crisis of form in front of goal.

“Football is really dynamic,” said Pochettino. “What we have today maybe tomorrow disappears. We need to be ready if we need more or not or maybe we go through the pre-season and we realise we need to improve in different positions or add more players that can score.

“It’s really dynamic and we’re going to assess every single day the situation.”

The manager added that Chelsea’s owners will need to check in with him before paying visits to the Stamford Bridge dressing room as he was formally unveiled as the club’s new manager.

Co-controlling owner Todd Boehly frequently entered the dressing room under successive head coaches last season, telling the players after a defeat to Brighton in April that their season had been “embarrassing.”

Pochettino began work at Cobham on Monday just over a month after he was confirmed as permanent successor to Graham Potter, who Boehly sacked just seven months after appointing him.

The Argentinian is tasked with resurrecting the club after they suffered their worst season in 29 years last campaign, finishing 12th and failing to mount a credible challenge for silverware despite the owner’s Clearlake Capital consortium forking out over £600million on transfers.

Pochettino said he felt it was his responsibility to create the kind of culture where people clearly understand their place and function in the wider collective.

“We need to understand that they own the football club,” he said when asked whether the hierarchy would be welcome on his watch to address the players post-match.

“We need to respect that. The thing is to talk about how we need to behave because that is an important thing.

“The culture of football in England is a lot to understand. My responsibility also is to help and to add our knowledge and capacity to create this culture where everyone knows how to behave in different situations.

“For me, more than welcome if the owner comes to the dressing room, to the training ground. But always they need to communicate with myself, I need to know, and to prepare the people to receive.

“In here (the dressing room) it’s really special in England. Maybe in another country it’s different, but here it’s this way.

“The manager has some influence in all football clubs, for the fans, for the players, for the staff and the media. Altogether we need to create this. We are there to guide all the people that are involved in this football club, to try to create the best atmosphere and try to work and perform in the best way.

“I am more than happy if they are close to us. But they are the owners. The players, the fans, the media – the coach is who decides how things are going to work in the dressing room, on the pitch, on the training ground.  Also with the sporting directors, we create the line to follow.”

Former captain John Terry tweeted on Friday that he has re-joined the club working with the academy.

The 42-year-old won five Premier League titles with Chelsea as well as the 2012 Champions League.

Levi Colwill will not be leaving Chelsea this summer in spite of continued interest from Liverpool and Brighton, the PA news agency understands.

The club are not willing to entertain offers for the 20-year-old defender, who starred for England Under-21s as they beat Israel 3-0 on Wednesday to advance to the European Championship final in Georgia.

He is currently contracted to Chelsea until the summer of 2024 with an option of another year if certain criteria are met.

Colwill spent last season on loan at Brighton where he made 22 appearances and established himself as a Premier League player as the Seagulls qualified for Europe.

Brighton had been keen to sign the defender permanently, but PA understands Chelsea are not prepared to listen to offers, including from Jurgen Klopp’s side who reportedly made a fresh enquiry this week.

It is also understood that Christian Pulisic’s proposed move to AC Milan is yet to be agreed with the two clubs still apart with their valuation of the player.

The United States international is surplus to requirements under Mauricio Pochettino and has also been the subject of interest from Ligue 1 side Lyon.

The French side have offered something closer to Chelsea’s valuation but it is believed the 24-year-old favours a move to San Siro.

The club confirmed on Thursday that Cesar Azpilicueta has ended his 11-year stay in west London – with the 33-year-old reportedly having agreed a return to Spain to join Atletico Madrid.

It means one of Pochettino’s first tasks as manager will be to appoint a new captain, with regular stand-in from last season Mateo Kovacic having been sold to Manchester City.

Azpilicueta made more than 500 appearances for the club since joining from Marseille in 2012 and established himself as a favourite at Stamford Bridge, winning the Premier League in 2015 and 2017 as well as leading the side to victory in the Champions League in 2021.

An FA Cup, League Cup and Europa League winner, he appeared in a club-record 13 major cup finals.

Co-controlling owner Todd Boehly told the club’s website: “Coaches and team-mates past and present have trusted (Azpilicueta) to lead by example as captain.

“He has done so immaculately on and off the pitch, something for which we are grateful.”

New Manchester United signing Mason Mount says he left Chelsea with it having become clear “several months ago” that he was not in the club’s plans for the future.

The England midfielder completed his move from the Blues to United this week on a deal to 2028, with the option of a further year, for what is understood to be an initial fee of £55million.

Mount told MUTV: “Several months ago I think it became clear that I wasn’t in Chelsea’s plans moving forward and once I knew that United were involved, my decision was made.

“It’s a massive club, huge, iconic players have played here, and I wanted to be a part of that from the beginning. Getting in early, ready for pre-season to start, was a main objective of mine as well.”

The 24-year-old – who had an 18-year association with Chelsea, played 195 times for them, scoring 33 goals, and helped them win the Champions League in 2021 – added: “I’ve always seen myself as a midfielder, a number eight that can obviously get forward and attack, try to score goals, create goals, but also be able to do the other side as well and defend and help the team when we’re under pressure. That’s a massive focus of mine.

“I know what I can bring to this team and now it’s about going and doing it on the pitch.”

Mount, set to wear the number seven shirt in Erik ten Hag’s United team, cut short a family holiday in Disneyland to finalise the deal.

He said: “We had a little trip to Disneyland, for the niece mainly – I enjoyed it as well, of course!

“We came back a bit early just to make our way up here, drive up here, see what the trip’s like and everything. But it was well worth it, and it’s great to be up here now.

“It’s been an amazing couple of days, coming here, seeing everyone, meeting everyone at the training ground, such a warm welcome. I feel very much at home already.”

Manchester United have completed the signing of Mason Mount from Chelsea on a contract to 2028 with the option of a further year, the club have announced.

The PA news agency understands the fee agreed for the 24-year-old England midfielder is an initial £55million.

Mount – who came through the ranks at Chelsea and made 129 Premier League appearances for them, scoring 27 goals and providing 22 assists – said in a statement from United: “It’s never easy leaving the club where you grew up, but Manchester United will provide an exciting new challenge for the next phase of my career.

“Having competed against them, I know just how strong a squad it is that I’m joining, and I can’t wait to be part of this group’s drive to win major trophies.”

Mason Mount has confirmed that he will be leaving Chelsea after 18 years at the club.

The 24-year-old came through the ranks at Stamford Bridge and since making his first-team debut in 2019 has gone on to score 27 goals and provide 22 assists in 129 Premier League appearances.

The PA news agency understands that Manchester United have agreed a deal to sign the midfielder for an initial £55million.

A post shared by Mason Mount (@masonmount)

Mount, who won the Champions League with Chelsea in 2021 and has earned 36 caps for England, posted a farewell message to Blues fans on Instagram.

He said on Instagram: “Hi Chelsea fans, given the speculation over the last six months this may not come as a surprise to you, but it doesn’t make it any easier to tell you that I’ve made the decision to leave Chelsea.

“I feel you deserve more than just a written statement, so I wanted to tell you directly how grateful I’ve been for all of your support over the last 18 years.

“I know some of you won’t be happy with my decision, but it’s what’s right for me at this moment in my career.

“I joined Chelsea when I was six years old and we’ve been through a lot together.

“Winning the Youth Cup, my Player of the Year awards, the Super Cup, the Club World Cup and of course that unforgettable night when we won the Champions League.

“I want to say thank you to the academy, Jim and Neil for being so influential to me from such a young age.

“The managers I’ve worked under, Frank (Lampard), Thomas (Tuchel) and Graham (Potter), the backroom staff, the unsung heroes of Cobham, all of my teammates over the years that have become my brothers.

“My family for the continuous love and support and most importantly you guys for sticking with me throughout. Wish you all the best.”

Chelsea have signed England goalkeeper Hannah Hampton on a free transfer from Aston Villa.

The 22-year-old, capped twice by her country and named in Sarina Wiegman’s squad for this summer’s World Cup, has signed a three-year deal after her contract with Villa expired.

She brings Women’s Super League experience from stints with both Birmingham and Villa, having made 15 appearances while helping the latter to a fifth-placed finish last term.

Hampton was part of England’s trophy-winning squad at Euro 2022 and also has honours to her name from the Finalissima earlier this year and 2022’s Arnold Clark Cup.

In joining the reigning WSL champions, she now wants to add club silverware to her collection.

“I’m very excited,” Hampton said on the Chelsea website. “It’s a massive club, it’s an honour to be a part of this and to be able to wear the club’s badge. I want to keep improving, to help the team however I can and I’d love to win some trophies with the club at the same time.”

Hampton began her career with Villarreal in Spain after moving to the country as a youngster, but then returned to England with Stoke before joining hometown club Birmingham, making her senior debut in 2017 and making 50 appearances before switching to rivals Villa in 2021.

Chelsea boss Emma Hayes added: “There is no doubt that Hannah is one of the best young goalkeepers in the world. Her performances have been improving year on year, and we have high hopes for her future with us.”

Chelsea have announced the signing of Portugal Under-21 international Diego Moreira from Benfica.

Moreira, 18, joined Benfica from Standard Liege in 2020 and was part of the side which won the 2022 UEFA Youth League.

Having made his senior debut in May 2022, Moreira featured regularly for Benfica B last season.

The teenage winger is part of Portugal’s squad at the European Under-21 Championship, where they will face England in the quarter-finals on Sunday.

Moreira’s arrival on a free transfer follows on from the signings of forwards Nicolas Jackson from Villarreal and Christopher Nkunku from RB Leipzig, while Ruben Loftus-Cheek has completed a permanent move to AC Milan.

Loftus-Cheek’s departure is one of several recent outgoings as new Blues boss Mauricio Pochettino reshapes his squad ahead of the start of the season.

Arsenal completed the signing of midfielder Kai Havertz, while N’Golo Kante, Kalidou Koulibaly and goalkeeper Edouard Mendy all headed for Saudi Arabia.

The PA news agency understands that midfielder Mason Mount is also set to depart after Manchester United agreed to sign the England international for an initial £55million.

Chelsea have announced the signing of forward Nicolas Jackson from Villarreal.

The 22-year-old joins the club on an eight-year deal after scoring 12 goals for the LaLiga side last season.

He began his career at Senegal Premier League side Casa Sports before moving to Villarreal in September 2019.

A successful season with the Spanish side saw him make 38 appearances in all competitions for the club and he was called up to represent Senegal at the World Cup.

Co-sporting directors Laurence Stewart and Paul Winstanley told the Chelsea website: “We are excited to welcome Nicolas to Chelsea. He is a young player with big potential, as he showcased for Villarreal last season.

“We believe he is ready for this next step in his career and look forward to him working with our new head coach, Mauricio Pochettino, and his Chelsea teammates.”

Jackson’s arrival came shortly after the Blues confirmed that Ruben Loftus-Cheek had completed a permanent move to AC Milan.

The 27-year-old joins Milan on a four-year deal running until June 2027.

His departure from Chelsea comes after 19 years with the club, having joined their academy in 2004.

He made 155 appearances for the Blues, scoring 13 times, and earned Premier League, Europa League and UEFA Super Cup winners’ medals during his time there.

An impressive loan spell with Crystal Palace also saw Loftus-Cheek selected for the England squad who reached the semi-finals of the 2018 World Cup in Russia.

However, he struggled for game time under successive managers during the second half of last season.

His move comes as part of several recent outgoings from Stamford Bridge, with N’Golo Kante and Kalidou Koulibaly among those joining sides in Saudi Arabia’s Professional League.

Earlier this week, goalkeeper Edouard Mendy joined Saudi side Al-Ahli, while Arsenal completed the signing of midfielder Kai Havertz.

The PA news agency understands that Mason Mount is also set to depart after Manchester United agreed to sign the England midfielder for an initial £55million.
