Chelsea have completed the signing of Atletico Madrid midfielder Saul Niguez on loan for the remainder of the season.

The European champions were successful with a late move for Saul on deadline day and reportedly have an option to buy for £30million (€34m) after paying an initial loan fee of £5m (€5.8m).

Saul had been linked with Manchester United and Liverpool previously but will get his first experience of playing in the Premier League for the Blues.

The 26-year-old was part of Atleti's title-winning side in LaLiga last season, but Diego Simeone refused to rule out the prospect of the player leaving after a 2-2 draw with Villarreal on Sunday.

Saul is contracted to the reigning Spanish champions until 2026 but may have played his last game for the club.

"I am very excited to start this new challenge with Chelsea. Blues fans, I am one of you now and I can't wait to wear the shirt, start training and see all of you. See you soon!" Saul said.

Saul's arrival comes after Chelsea paid out a club-record fee to bring Romelu Lukaku back to Stamford Bridge from Inter earlier in the same transfer window.

Club director Marina Granovskaia said of the latest recruit: "We welcome Saul to the club and believe he completes our squad as we compete for honours in five different competitions this season.

"He is a proven winner, a player with huge experience and we know he will be very well-suited to the challenges that face us on all fronts in the coming year."

Arsenal have signed versatile defender Takehiro Tomiyasu from Bologna and allowed Hector Bellerin to join Real Betis on loan for the rest of the season.

The Gunners are reported to have paid Serie A side Bologna £17million (€19.8m) to land the Japan international on deadline day.

Tomiyasu, 22, had previously been linked with Tottenham but has instead joined their north London rivals on a long-term contract.

Arsenal boss Mikel Arteta told the club's official website: "Takehiro is a strong defender with good experience in Serie A and at international level.

"He's a versatile defender with great defensive qualities, high technical ability and composure on the ball.

"He will be an important member of our squad. We look forward to Takehiro joining up with us when he returns from international duty."

Long-serving full-back Bellerin has left the bottom side in the Premier League to return to his homeland with Betis.

The 26-year-old, who joined the London club a decade ago, won the FA Cup three times during his time with the Gunners.

Goalkeeper Alex Runarsson and midfielder Reiss Nelson also departed on loan for the rest of the season before the window closed, though Ainsley Maitland-Niles has remained at the club.

Emerson Royal has completed his move from Barcelona to Tottenham, joining the Premier League club on a deal that runs until 2026.

The full-back arrives to strengthen Spurs’ squad in a deal worth £21.5million (€25m), according to the selling club.

Emerson will provide competition for Japhet Tanganga and Matt Doherty on the right side of the Tottenham defence, with Serge Aurier seemingly falling out of favour under Nuno Espirito Santo.

The Brazil international departs Camp Nou having made just three appearances since Barca exercised the option to bring in the player from Real Betis, where he had spent the past two-and-a-half years.

Emerson moved to Spain in a three-way deal in January 2019, both Betis and Barca each paying half of the €12m fee owed to Atletico Mineiro.

The 22-year-old scored four goals during his LaLiga appearances, also assisting once as he played the most minutes of any Betis player across all competitions in the 2020-21 season (3,186).

He moves to England as a well-rounded defender, ranking second at Betis for recoveries (163), third for chances created from open play (30) and second for successful duels (246).

It was confirmed by Spurs that the deal is subject to international clearance and a work permit being granted.

Chris Richards has signed a new contract with Bayern Munich to keep him at the club until 2025 before returning on loan to Hoffenheim.

The 21-year-old joined from FC Dallas in 2019, initially signing a contract until June 2023, and has penned a further two-year extension with the Bundesliga champions.

Richards spent the majority of last season on loan at Hoffenheim, starting 11 top-flight fixtures before a thigh injury cut his season short in May.

The United States international impressed as a ball-playing defender, ranking third among Hoffenheim defenders for recoveries per 90 minutes (6.37) and second for successful passes (55.98).

On confirming Richards' new deal, Bayern's sporting director Hasan Salihamidzic said on Tuesday: "We are very pleased with the development Chris Richards has taken with us, which is why we have also extended his contract.

"Chris is a young player who will now gain more Bundesliga experience in Hoffenheim, and that's exactly what he needs."

The loanee could feature as soon as September 11 for Hoffenheim after the international break as they host Mainz.

Real Madrid have announced the signing of midfielder Eduardo Camavinga from Rennes.

The 18-year-old France international agreed a six-year contract with Los Blancos in a deal that could cost up to €45million, according to reports.

It is the first time Madrid have spent money on a transfer fee since 2019, when they signed Eden Hazard from Chelsea for €100m.

Camavinga had been linked with a host of major European clubs, including Manchester United and Paris Saint-Germain, but Madrid elected to make a late push to sign him before the transfer deadline after it became clear that landing Kylian Mbappe from PSG would be impractical.

The teenager, who made 71 Ligue appearances for Rennes and 88 in total, is Madrid's second signing of this window following the free transfer of David Alaba from Bayern Munich.

At 18 years and nine months old, he is the youngest outfield player to feature in that many games in France's top flight since Basile Boli in 1985.

In making his senior France debut on September 8 last year, Camavinga was the youngest player to do so since Maurice Gastiger against Luxembourg 107 years ago.

Only Gastiger (17 years and five months) scored for Les Bleus at a younger age than Camavinga, who was 17 years and 11 months old when he netted against Switzerland last October.

In 2019-20, Camavinga's breakthrough season at Rennes, he attempted 105 tackles in top-flight football. Among midfielders in Europe's top five leagues, only Declan Rice (116) and Wilfred Ndidi (129) attempted more. 

Camavinga will provide competition in midfield for Casemiro, Toni Kroos, Luka Modric and Federico Valverde at Madrid.

Barcelona prospect Ilaix Moriba has completed a move to RB Leipzig for an initial fee of €16million.

Tottenham were rumoured to be interested but Marcel Sabitzer leaving for Bundesliga rivals Bayern Munich on Monday opened the door for Leipzig's new arrival.

Moriba was unable to negotiate new terms with Barca over his contract, which was due to expire at the end of the 2021-22 season.

Barca president Joan Laporta said Moriba would not feature for the first team if he did not commit his future and Leipzig have taken advantage of the situation to get the player to Germany.

"I'm very happy that my move to RB Leipzig worked out - an exciting club that has always had an offensive style of play and therefore fits my game very well," Moriba, who has signed a five-year deal, told his new club's website. 
 
"I am convinced that Leipzig is the ideal next step for my career and further development - that was ultimately the reason for my decision to change.  
 
"My whole concentration is now fully on arriving at the club, in the team and in the city, in order to then perform on the pitch as quickly as possible. We have ambitious goals for this season and I can hardly wait for the challenge." 

Moriba broke into Ronald Koeman's plans last term, making 18 appearances across all competitions, providing two assists and scoring his sole senior goal against Osasuna.

His finish against Osasuna made him the youngest player to score from outside the box in LaLiga last season, while his debut assist made him the youngest to do so in the competition this century.

The 18-year-old averaged 3.2 dribbles per 90 minutes, a total bettered by only four team-mates, completing 2.8 of those to achieve a success rate of 89.3 per cent.

Despite the limited sample size, Miralem Pjanic was the only team-mate to boast a more successful record of those to attempt more than one dribble per 90 minutes.

In March, Moriba was also rewarded with his Champions League debut, appearing as a late substitute against Paris Saint-Germain.

Barca confirmed the sum received, as well as revealing a further €6m could be due if certain variables are met. They will also get 10 per cent of any future sale, should the teenager move on from Leipzig.

Real Madrid have announced the signing of midfielder Eduardo Camavinga from Rennes.

The 18-year-old France international agreed a six-year contract with Los Blancos in a deal that could cost up to €45million, according to reports.

It is the first time Madrid have spent money on a transfer fee since 2019, when they signed Eden Hazard from Chelsea for €100m.

Sergio Busquets and Jordi Alba have followed Gerard Pique in taking pay cuts to allow Barcelona to register Sergio Aguero and reduce financial concerns.

Lionel Messi could not be signed to a new deal because of spiralling costs at the Catalan club and, with no signs of improvement, Barca risked not being able to register new signings Memphis Depay, Eric Garcia and Aguero.

However, after Pique agreed to a salary reduction and deferral of payments, Ronald Koeman's side confirmed they were able to register Depay, Garcia and Rey Manaj.

Alba and Busquets have now, too, agreed to alterations to the terms of their contracts.

Both players will collect reduced wages for this season and deferred payments for the rest of their deals, with also Sergi Roberto reported to be negotiating changes to his terms.

The agreements with Busquets and Alba mean cash-strapped Barca can now register Aguero, who is expected to be out injured until the middle of October, while avoiding complications with financial fair play regulations.

Left-back Alba created the second most chances at the club last term in LaLiga (53), while Busquets led the way for tackles and interceptions while also completing the second most passes.

Juventus have signed PSV midfielder Mohamed Ihattaren and loaned the teenager to Sampdoria.

Ihattaren has signed a four-year deal with Juve having arrived for a fee reported to be in the region of €5-6million.

The 19-year-old playmaker, who had less than a year remaining on his PSV contract, must wait for his Bianconeri debut after he was allowed to join Serie A rivals Sampdoria for the remainder of the season.

Ihattaren made his PSV debut aged 16 and went on to score 10 goals in 74 appearances for the Eredivisie side.

PSV director of football John de Jong said: "Mohamed has gone through ups and downs in the last few years. As a young prospect, his career got off to a bright start but it has taken a turn and he has not fulfilled his potential for various reasons.

"It is a great pity, in particular for Mohamed himself. We are happy for Mohamed that he has made a move to Italy and hope he will live up to his potential."

Radu Dragusin has also made the move from Juve to Sampdoria for the rest of the campaign.

Juventus earlier brought Moise Kean back to the club from Everton on a two-year loan with an obligation to buy following the departure of Cristiano Ronaldo to Manchester United.

Kean returns to Turin two years after the forward left for the Premier League in a £27million (€31.5m) move, having signed a five-year deal with the Toffees.

Juve will pay €7m (£6m) for the striker's loan spell, payable over two years. They will be obliged to re-sign him on a permanent basis for a fee that could reach €31m (£26.6m) if certain objectives are met.

Chelsea have not made a formal offer for Jules Kounde since Wednesday and there have been no negotiations since Friday, according to Sevilla sporting director Monchi.

Kounde is reportedly a target of Thomas Tuchel's men, with Manchester City previously said to be interested, and the centre-back was left out of the trip to Elche on Saturday.

However, Monchi declared in a press conference on Tuesday that the LaLiga outfit have not heard from Chelsea since Friday, their last formal offer being submitted two days prior.

"The only possibility is that they [Chelsea] pay the clause," Monchi said. "It's €80million euros. There has been interest from many teams, most of them rejected by the player himself.

"The footballer did like Chelsea. The first offer we received from Chelsea. It was last Wednesday, at five o'clock, with an amount that did not satisfy what we wanted.

"It was important, we did not underestimate the amounts. I had already spoken with the player to tell him that the longer time passed, the more difficult the operation was.

"We responded with a counter-offer to Chelsea and since Friday night there has been no more negotiation."

When comparing Kounde to Chelsea centre-backs across their respective domestic leagues last term, the Sevilla defender ranked first for clean sheets (15).

Only Antonio Rudiger made more tackles than Kounde (31 to 27), while none of the Blues could top the 22-year-old's 40 interceptions, 100 clearances or 102 aerial duels won.

Kurt Zouma, Thiago Silva and Andreas Christensen all boasted better passing accuracy than Kounde's 90.11 per cent, however.

Speculation persists, but Monchi remains confident of keeping his defender.

"I don't think anyone will pay it [the release clause], but there is a time to react," the Sevilla chief continued.

"The decision not to travel to Elche was made jointly by all parties.

"We asked him if he was 100 per cent to travel, he thought about it and then said yes. But we made that decision.

"Jules is not a superhero, even if he is a great guy or a great professional. It is normal for the player to have some doubts. He did not go on vacation, he is concentrating with France."

Transfer deadline day has already been a busy one, even if the biggest move of all was one that was expected.

Manchester United, Juventus and West Ham have all made moves, while changes are expected at Arsenal and Tottenham before the window closes.

There is also a good chance of a young France star joining Real Madrid – but it's not Kylian Mbappe.

Here is a round-up of some of the deadline-day deals, and what could be coming...

Ronaldo in, Cavani out?

The biggest deal of the day was concluded early, as Manchester United completed the signing of Cristiano Ronaldo from Juventus for an initial £12.9million (€15m).

The Portugal star dedicated his return to Old Trafford to Alex Ferguson after his two-year contract was announced by the Red Devils.

Ronaldo's arrival has complicated things for Edinson Cavani, though. The striker was convinced to spend another year at the club by Ole Gunnar Solskjaer after impressing last season, but his pre-season was disrupted due to personal reasons and he did not start any of United's first three league games of the season.

There are reports Barcelona are interested in signing Cavani as Ronald Koeman is desperate for another striker, but the Red Devils are expected to resist offers unless they are particularly lucrative. Of course, if Cavani does leave, it would free up the number seven shirt for Ronaldo.

United's business is mostly concluded but Dan James is expected to sign for Leeds United on deadline day for a reported £25m.

Real Madrid close to Camavinga

With Kylian Mbappe apparently not going to get his move in this window, Real Madrid have turned their attentions to Rennes midfielder Eduardo Camavinga, who is expected to sign for Carlo Ancelotti's side before the deadline.

With Mbappe staying put at Paris Saint-Germain for now, any dramatic late offer for Borussia Dortmund's Erling Haaland looks unlikely. BVB have in fact bolstered their squad, signing Marin Pongracic on loan from Wolfsburg.

Kean and Vlasic on the move

Juventus moved quickly to confirm Ronaldo's replacement, announcing a two-year loan with a potential obligation to buy for Everton striker Moise Kean. Kean returns to Turin for an initial €7m (£6m) after having left for the Toffees two years ago.

There was also video footage early on Tuesday of Junior Messias arriving for a medical at Milan, the 30-year-old apparently poised to sign on loan from Crotone.

Croatia international Nikola Vlasic has secured his move to West Ham from CSKA Moscow for a fee said to be worth £25m. His arrival would appear to cast doubt on any further bid from the Hammers for Jesse Lingard, who impressed on loan last season.

Brighton and Hove Albion have also been active, signing Getafe left-back Marc Cucurella – formerly of Barca – after the Seagulls matched his €18m (£15.5m) release clause.

Leicester City are said to be exploring the opportunity to bring in Ademola Lookman on loan from RB Leipzig, while Odsonne Eduoard is close to a move to Crystal Palace from Celtic.

Spurs and Arsenal still active – but will Chelsea spend again?

Tottenham are expected to complete a deal for Barca's Emerson Royal for around £25.8m (€30m). That sale could give Barca just a little leg room when it comes to pursuing the striker Koeman wants.

There are also likely to be changes at Arsenal. With Hector Bellerin tipped to sign for Real Betis on loan, the Gunners are said to be close to signing Takehiro Tomiyasu from Bologna.

Meanwhile, Reiss Nelson could be on the verge of a loan move to Feyenoord, who had agreed to sign Amad Diallo from Manchester United for the rest of the season until the winger suffered a thigh injury.

Chelsea have already spent huge money on Romelu Lukaku, but it remains to be seen whether a loan for Saul Niguez or a permanent deal for Jules Kounde could be concluded.

Cristiano Ronaldo has completed his sensational move to Manchester United on an initial two-year contract with an option for a further year.

The Red Devils last Friday confirmed they had agreed a deal with Juventus to bring the Portugal captain back to Old Trafford.

Ronaldo is now officially a United player once again, 12 years after the 36-year-old forward left the club to join Real Madrid.

United will pay £12.9million (€15m), rising to £19.7m (€23m), for the five-time Ballon d'Or winner, who scored 118 goals in 292 appearances under Alex Ferguson in his first spell at the club.

Ronaldo had appeared poised to join Manchester City last week before United made a late effort to tempt him back to Old Trafford, with Bruno Fernandes, Rio Ferdinand and even Alex Ferguson – according to reports – speaking with the player to convince him to snub Pep Guardiola's side.

Ferguson signed an 18-year-old Ronaldo from the Portuguese's boyhood club Sporting CP in 2003, and that raw talent went on to establish himself as one of the finest players in Premier League history.

His 31-goal season of 2007-08 has only ever been bettered once in a 38-match campaign (Mohamed Salah, 32 in 2017-18). In all competitions that term, Ronaldo netted 42 times as United won the Premier League – Ronaldo's third – and Champions League, while he later took home his first Ballon d'Or.

Nine goal-laden years followed at Real Madrid, where he became the club's all-time record scorer, and he remained a reliable frontman for Juventus, scoring 81 times in 98 Serie A matches since the start of 2018-19. In all competitions, Ronaldo has scored 674 goals in 895 appearances at club level.

As well as help them to challenge for a first league title since Ferguson retired in 2013, United will hope Ronaldo can carry them further in the Champions League. A five-time winner of the trophy, he leads the way for goals in the history of the competition, scoring 134 times in 176 games, 14 ahead of his nearest competitor Lionel Messi.

A whirlwind day last Friday saw Manchester United reach an agreement with Juventus to bring Cristiano Ronaldo back to the club.

The deal was confirmed just hours after it had looked likely the Portugal star would be heading to Premier League champions Manchester City instead.

According to reports, United manager Ole Gunnar Solskjaer encouraged the club to enter the race when it began to seem inevitable Ronaldo would head to the Etihad Stadium. Contact from Bruno Fernandes, Rio Ferdinand and even Alex Ferguson helped persuade Ronaldo that a return to Manchester could mean only one thing.

It all made for a short-lived but extraordinary transfer saga that ended with United re-signing a player who made history with the club between 2003 and 2009, winning three Premier League titles, the Champions League and the first of his five Ballons d'Or.

Here, Stats Perform looks at some other deals that caused a shock in the sporting world...

Lionel Messi: Barcelona to Paris Saint-Germain, 2021

In the most sensational free transfer of all time, PSG again laid down a marker to the football world with the signing of Lionel Messi on a two-year contract. Just as he looked to sign a new Barcelona contract, the club informed him that their dire financial situation meant they could not bring their greatest ever player back under LaLiga's salary restrictions after his previous deal expired in June. A tearful Messi said farewell to the only club he had ever played for before heading to the fanfare of Paris and a reunion with Neymar.

Neymar: Barcelona to Paris Saint-Germain, 2017

The Brazilian had formed a potent attacking trio with Messi and Luis Suarez at Camp Nou but a move to PSG was inevitable when the French side met his world-record buyout clause of €222million. He has played an important role in their continued dominance of French domestic football but has so far been unable to guide them to Champions League glory. He was reduced to tears by his side's 1-0 defeat to Bayern Munich in the 2020 final and then failed to inspire the team in the 2021 semis as Manchester City knocked them out.

LeBron James: Cleveland Cavaliers to Miami Heat, 2010

Basketball icon James announced he would sign with the Miami Heat instead of returning to his hometown team, the Cleveland Cavaliers. Then a two-time NBA Most Valuable Player and a six-time All-Star, James added to the spectacle of the stunning move by announcing it on a special television broadcast called The Decision. He enjoyed four years in Miami, where he won a pair of NBA titles, before returning to the Cavaliers in 2014. 

Tom Brady: New England Patriots to Tampa Bay Buccaneers, 2020

Few people expected Brady to leave the Patriots after 20 years and six Super Bowl victories. Not only did one of the game's greatest ever quarterbacks leave, but he joined one of the least successful franchises in NFL history and instantly guided them to glory, leading the Buccaneers to the franchise's second Lombardi Trophy with a 31-9 triumph over the Kansas City Chiefs in Super Bowl LV.

Luis Figo: Barcelona to Real Madrid, 2000

Should Messi ever return to Camp Nou as an opposition player it is unlikely he will be on the receiving end of the kind of abuse that greeted Figo. Barca fans threw bottles, lighters and even a pig's head at the Portuguese star when he went back to Camp Nou with Los Blancos in the seasons following his controversial move.

Wayne Gretzky: Edmonton Oilers to Los Angeles Kings, 1988

In 1988, the Edmonton Oilers and Los Angeles Kings agreed a deal that shook the NHL to its core. The trade left Canada in disbelief, with a member of the country's parliament even proposing the federal government block the trade or buy Gretzky's contract and sell it to another Canadian team. "The Great One" would go on to enjoy eight successful years in Los Angeles before spells with St. Louis Blues and New York Rangers.

Cristiano Ronaldo has completed his sensational move to Manchester United on an initial two-year contract with an option for a further year.

The Red Devils last Friday confirmed they had agreed a deal with Juventus to bring the Portugal captain back to Old Trafford.

With Kylian Mbappe staying put, Real Madrid are looking elsewhere in France. 

Los Blancos have their sights set on an even younger talent. 

Teenage midfielder Eduardo Camavinga could be on the move from Rennes.

TOP STORY – CAVAMINGA TO REAL MADRID

In the final hours before the transfer window closes, Eduardo Camavinga appears poised for a long-rumoured departure from Rennes. 

The 18-year-old France international will join Real Madrid in a €31million deal, Fabrizio Romano reports, with Goal saying he will get a five-year deal.

Paris Saint-Germain and Manchester United also were interested in the midfielder.
