Cristiano Ronaldo is set to be playing back at Old Trafford again in 2021-22 after Manchester United confirmed they have reached an agreement with Juventus for the transfer of the Portugal great.

While personal terms, a medical and visa are still to be sorted out for Ronaldo, it would take something remarkable to stop him from joining now after a deal reportedly worth up to €23million (£19.7m) was agreed with Juve on Friday.

For a short while it looked as though Ronaldo – who had asked to leave the Bianconeri – was heading to Manchester City after they missed out on the signing of Harry Kane.

But apparent interventions from Ronaldo's former United manager Alex Ferguson and old team-mate Rio Ferdinand may have swung the race in the Red Devils' favour.

Ole Gunnar Solskjaer seemed to open the door to Ronaldo during his news conference on Friday, and just a few hours later United confirmed a deal had been struck with Juventus.

Following confirmation of the deal, Stats Perform takes a look at greats who went back to their spiritual home, starting with the Portugal captain…

Cristiano Ronaldo – Manchester United

Ronaldo spent six years at Old Trafford during his last spell, arriving as a lanky teenager who probably averaged four stepovers per minute before leaving as a Ballon d'Or winner and an ice-cold finisher. His then-world record move to Real Madrid had been a long time coming and he spent nine years at the Santiago Bernabeu, becoming the club's all-time top scorer as he continued his transition from winger to out-and-out 'number nine'. There he won four Champions League titles before moving on to Juve, for whom he plundered 81 goals in 98 Serie A matches and picked up two Scudetti. But now he is all set for a return to England – whether he can match the standards he set last time remains to be seen, with his 31-goal haul of 2007-08 only bettered once in a 38-match season, though United fans will be convinced he can fire them to a first league title since Ferguson left.

Arjen Robben – Groningen

Robben's first retirement lasted just a single season, having announced last year he would be returning to his boyhood club Groningen for the 2020-21 campaign. Robben, now 37, initially brought an illustrious playing career to an end in July 2019 shortly after his 10-year spell with Bayern Munich finished. Although at the time he was linked with a potential return to the team that gave him his professional debut, Robben – who suffered with numerous injury problems throughout his career – opted to retire. He then caused something of a shock as he finally went back to the place where it all began, but once again injuries blighted his availability, restricting him to just seven Eredivisie appearances in 2020-21. Club director Mark-Jan Fledderus wanted him to stay on for another year, but when Robben said at the end of the season that he was going to have a long think about his future, the writing was seemingly on the wall. Another U-turn appears unlikely.

Juan Roman Riquelme – Argentinos Juniors

Perhaps more synonymous with Boca Juniors, where he made his professional debut and also spent most of his final years, Riquelme also had a strong affinity with Argentinos Juniors. He came through the club's academy in the early-to-mid 1990s, before then finishing his immense career at Estadio Diego Maradona in 2014, having also played for Barcelona, Villarreal and Argentina. Although the iconic attacking midfielder appeared close to joining Paraguay's Cerro Porteno the following year, the move never materialised.

Dirk Kuyt – Quick Boys

Kuyt briefly came out of retirement three years ago to help Quick Boys, with whom he spent 13 years as a youth. Playing in the Derde Divisie Saturday league, Kuyt was already working as assistant at the time, but made himself available for selection during a striker shortage and he made three appearances. The former Netherlands and Liverpool forward had retired the year before following a second spell with Feyenoord, where he had made his initial breakthrough in the mid-2000s, his form at the time earning a move to Anfield.

Rafael Marquez – Atlas

One of Mexico's greatest players, Marquez's longevity at such a high level was nothing short of incredible, as he accumulated 147 international caps. After breaking into the Atlas team as a teenager having come through their academy, the elegant centre-back enjoyed a sparkling career in Europe, winning 14 titles across spells with Monaco and Barcelona. Time with New York Red Bulls, Leon and Hellas Verona followed, before a final two-year stint back at the Jalisco ended in 2018. Although plagued by off-field allegations towards the end of his career, Marquez went on to become the club's sporting president, before standing down last in 2019 to focus on other areas of the sport. He was expected to be taking up a youth coaching role at Barca this season, but the deal ultimately fell through.

Henrik Larsson – Hogaborgs

While the Swedish club most may associate with Larsson is Helsingborgs, he actually made the breakthrough at a smaller side – Hogaborgs. It was here where he trained from the age of six, before eventually becoming a regular in the senior side and earning a move away. A trophy laden career followed, taking him to Feyenoord, Celtic, Barcelona and Manchester United. Although he retired in 2009, he returned to the pitch for Raa in the Swedish third tier three years later, before then finding himself back in the team at Hogaborgs in 2013, helping out due to an injury crisis despite him only previously being registered to a casual team for 'seniors'. This gave him the chance to play alongside his son, Jordan.

Carlos Tevez – Boca Juniors

The Tevez-Boca love affair has dominated most of the striker's successful and complex career. After coming through their youth ranks, the feisty forward was seen as the heir to Maradona. A brief stint in Brazil with Corinthians followed, but Europe had long since beckoned, even if West Ham was by no means the expected destination. He went on to play for Man Utd and City, increasing tension between the clubs, before then going to Juventus, but throughout this time Tevez seemed to long for a return to Boca. He went back to La Bombonera in 2015, his homecoming interrupted by a brief spell with Shanghai Shenhua in 2017 in the Chinese Super League, though even Tevez acknowledged he saw his time in China as a "holiday". "He filled Santa's sack with dollars and now he has returned to Boca," was Maradona's assessment upon 'El Apache's' return from the CSL. His third spell with Boca ended in June 2021 and it remains to be seen if he ever plays for another club.

Gianluigi Buffon – Parma

Buffon likes a comeback. Having returned for a second spell at Juventus in 2019, the goalkeeping great departed the club for a second time at the end of 2020-21. The Italy legend suggested he had not finished playing yet and Parma quickly emerged as a potential destination despite their recent relegation to Serie B. After a few weeks of contemplation, it was confirmed that Buffon was heading back to the club where he made his name. Now 43, the iconic stopper is wearing Gialloblu for the first time in 20 years, and he is set to remain with them until he turns 45, given he signed a two-year contract. What happens after that is anyone's guess but calling it a day with his first club could be a satisfyingly romantic conclusion to a remarkable career – that or he ends up at Juve again!

Karl-Heinz Rummenigge feels Leroy Sane's situation at Bayern Munich is similar to the difficulties Arjen Robben went through in his early years at the club.

Sane, signed from Manchester City in July 2020, has struggled to string together a consistent run during his time with the Bundesliga champions.

The flying winger was one of the Premier League's most exciting attackers during his time with City yet found himself a peripheral figure under Hansi Flick last term. On Sunday, he was taken off at half-time after drawing jeers from Bayern's support in Julian Nagelsmann's first competitive home game in charge.

Sane had 28 touches, two attempts – neither of which were on target – and created one chance in the first half against Cologne, with his replacement Jamal Musiala coming on to make an impact by teeing up Robert Lewandowski's opener in an eventual 3-2 win for Bayern.

Rummenigge, who left his role on the Bayern board at the end of last season, believes the Germany international's predicament, and the treatment he received from some Bayern fans, is akin to the reaction Robben initially received.

Robben joined Bayern from Real Madrid in 2009 and went on to become a club legend, but Rummenigge recalled that, the Netherlands attacker once considered leaving.

"At first I didn't like it, I feel sorry for him [Sane]," Rummenigge said on Bild's Reif ist live podcast about what happened on Sunday.

"He tries but has no confidence. He didn't play a good game. With his transfer fee and salary, the criticism of the fans is slowly coming up.

"I remembered 2012 in the stadium. There was the famous home final [in the Champions League]. It reminded me of the sad Arjen Robben. He missed a penalty in the final. 

"Arjen was almost ready to ask for his release. But we said: 'No, we won't do that.' He was an important player for Bayern Munich. We supported him. 

"Jupp Heynckes built him up as a coach. He was extremely ambitious. The result: a year later he was the match-winner in the Champions League final against Dortmund."

Since starring with a goal and two assists against former club Schalke on his debut, Sane has featured 46 times across all competitions for Bayern, which ranks him third behind stalwarts Manuel Neuer and Thomas Muller (both 48).

However, only 28 of those appearances have been starts, while he has been taken off 22 times – Sane trails only Serge Gnabry (23) and Kingsley Coman (29) in that regard.

Sane has contributed nine goals and eight assists. His tally of 45 chances created is just above former team-mate David Alaba (38) but way behind Muller, who tops the list for Bayern across the period with 125.

Arjen Robben's playing days are officially over (again), with the Bayern Munich and Netherlands great confirming on Thursday that he is hanging up his boots.

Of course, this is not the first time Robben has made such a decision – he initially retired in 2019 after a decade with Bayern before returning to his first club Groningen.

Although the fairy-tale conclusion he may have hoped for never quite materialised, ending his career where it all began has seen his playing days come full circle.

In honour of Robben's retirement, Stats Perform takes a look at greats who have gone back to their spiritual home in the twilight stages, starting with an overview of the king of inverted wingers…

Arjen Robben - Groningen

Robben's first retirement lasted just a single season, having announced last year he would be returning to his boyhood club Groningen for the 2020-21 campaign. Robben, now 37, initially brought an illustrious playing career to an end in July 2019 shortly after his 10-year spell with Bayern finished. Although at the time he was linked with a potential return to the team that gave him his professional debut, Robben – who suffered with numerous injury problems throughout his career – opted to retire.

Although plagued by off-field allegations towards the end of his career, Marquez went on to become the club's sporting president, before standing down last in 2019 to focus on other areas of the sport. He is expected to be taking up a youth coaching role at Barca next season.

Juan Pablo Angel - Atletico Nacional

Angel perhaps never quite lived up to the expectations he set during his early days as part of River Plate's so-called 'Fantastic Four' with Javier Saviola, Ariel Ortega and Pablo Aimar, having joined from Colombia's Nacional. Nevertheless, he became a fan favourite at Aston Villa in the Premier League, before spending six years in MLS with New York Red Bulls, Los Angeles Galaxy and Chivas USA. In 2013 he returned to Nacional for two seasons, having left them in 1997. He called it quits in late 2014, just a few days after losing to his former club River in the final of the Copa Sudamericana. "I am ending my career with a final between the two clubs I love the most," he said.

Henrik Larsson - Hogaborgs

While the Swedish club most may associate with Larsson is Helsingborgs, he actually made the breakthrough at a smaller side – Hogaborgs. It was here where he trained from the age of six, before eventually becoming a regular in the senior side and earning a move to Helsingborgs. A trophy-laden career followed, taking him to Feyenoord, Celtic, Barcelona and Manchester United.

His third spell with Boca ended in June 2021, though it remains to be seen if he ever plays for another club.

Gianluigi Buffon - Parma

Okay, he is not technically retired yet, so perhaps Buffon does not strictly qualify here. However, after departing Juventus for the second time at the end of 2020-21, the Italy great suggested he had not finished playing just yet. Parma quickly emerged as a potential destination despite their recent relegation to Serie B, and after a few weeks of contemplation, it was confirmed that Buffon was heading back to the club. Now 43, the iconic goalkeeper will wear the Gialloblu for the first time in 20 years, and he is set to remain with them until he turns 45, given he signed a two-year contract. What happens after that is anyone's guess but calling it a day with his first club could be a satisfyingly romantic conclusion.

— Parma Calcio 1913 (@1913parmacalcio) June 17, 2021

Arjen Robben has decided to bring his playing career to an end just a year after announcing his return with boyhood club Groningen.

Former Bayern Munich and Netherlands great Robben initially called it quits in 2019 following a decade in Bavaria, having seen the final few years of his time in the Bundesliga partially interrupted by fitness problems.

After a season away he announced in June 2020 that he was to return to football with Groningen, the club at which he started his career, in an attempt to help them out amid the coronavirus pandemic.

It was to be his first season in the Eredivisie since 2003-04, which was the last of his two campaigns with PSV prior to joining Chelsea.

However, injuries and fitness issues restricted Robben to just six league outings and he hinted at the end of the season that he may not return.

Now it is official that Robben has hung up his boots, with another U-turn somewhat more unlikely this time at the age of 37.

He said: "A year ago I announced my comeback as an FC Groningen player. I embarked on this adventure with great energy and enthusiasm.

"Looking back on the past season, I have to come to the honest conclusion that the number of match minutes was disappointing. After the last game I said I would take the time to make an informed decision about the future.

"That was very difficult, because the mind and the emotion were in direct opposition. The football heart wanted to move on, especially with that ultimate goal of a full Euroborg [Groningen's stadium] in prospect.

"But the decision to quit is fair and realistic. That is why from today I am no longer a player, but a supporter of our football club.

"I would like to thank all football supporters and enthusiasts for all the warm support and sweet messages I have received over the past year. That was wonderful and heartwarming.

"I wish everyone a great football season in full stadiums, but above all good health."

Groningen technical director Mark-Jan Fledderus was keen to stress that the club's wish was for Robben to carry on for another season, but his decision has been met with respect and understanding.

Fledderus said: "It was common knowledge that we really wanted Arjen to stick with it for another year, but we also said that we appreciate and respect every decision made by him.

"We are especially grateful to Arjen that he took the step last year to make his comeback at FC Groningen.

"What that decision has meant for the club is unique. It shows the incredible commitment to FC Groningen and his love of the club.

"That is unprecedented for a player with his track record. His presence and influence on and off the field was invaluable."

While the Groningen return perhaps was not the fairy tale ending he had hoped for, Robben's career was a glorious one.

Robben made his professional debut with Groningen in 2000 and spent two seasons there before joining PSV, where he won a league title in the 2002-03 season.

He won further championships in England, Spain and Germany with Chelsea, Madrid and Bayern respectively, in the process becoming one of the world's best wide players.

He helped win eight Bundesliga titles during his decade with Bayern, plus the Champions League in 2012-13, making 309 appearances across all competitions.

Despite the injuries, Robben still managed to score 144 times for Bayern, including six in 19 matches in his final campaign.

He won 96 caps for the Netherlands, scoring 37 times, and was part of the Dutch team that was beaten in the 2010 World Cup final by Spain in South Africa.

In a move that football purists, romanticists and aficionados of 1990s Serie A will be excited by, Gianluigi Buffon is returning to Parma after 20 years away.

Buffon came through the club's academy in the early '90s and made 220 appearances for them in all competitions, winning the Coppa Italia, Supercoppa Italiana and UEFA Cup during a six-year spell in the first-team.

Juventus made Buffon the world's most-expensive goalkeeper at the time when they paid €52million for him in 2001 and he played 685 times for them across two spells, 20 short of Alessandro Del Piero's club record.

Nevertheless, Buffon's longevity has ensured he is the record holder for the most Serie A appearances (657) and titles (10) in the league's history.

After leaving Juve at the end of the 2020-21 season, it was unclear what would be next for Buffon, but links with Parma began to stir despite their relegation to Serie B.

And on Thursday the club confirmed Buffon is back. While the days of challenging for major honours are long gone for Parma, the goalkeeping great represents a coup and the kind of transfer that tugs at heartstrings.

In honour of Buffon's momentous return, Stats Perform takes a look at other greats who've gone back to their spiritual home to close out their career.

Arjen Robben - Groningen

Arjen Robben's retirement lasted just a single season, as the Netherlands and Bayern Munich great announced last year that he was returning to his boyhood club Groningen for the 2020-21 campaign. Robben, now 37, initially brought an illustrious playing career to an end in July 2019 shortly after his 10-year spell with Bayern finished. Although at the time he was linked with a potential return to the team that gave him his professional debut, Robben – who suffered with numerous injury problems throughout his career – opted to retire. He then caused something of a shock as he finally went back to the place where it all began, but once again injuries blighted his season, restricting him to just seven Eredivisie appearances. It's unclear if he'll play on into 2021-22, though either way it's safe to assume Groningen will be where he retires once and for all.

Juan Roman Riquelme - Argentinos Juniors

Perhaps more synonymous with Boca Juniors, where he made his professional debut and also spent most of his final years, Riquelme also had a strong affinity with Argentinos Juniors. He came through the club's academy in the early-to-mid 1990s, before then finishing his immense career at Estadio Diego Maradona in 2014, having also played for Barcelona, Villarreal and Argentina.
