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.

Beste voetbalvrienden,

Ik heb besloten om te stoppen met mijn actieve voetbalcarrière. Een heel moeilijke keuze. Ik wil iedereen bedanken voor alle hartverwarmende steun!

Groetjes, Arjen pic.twitter.com/aAEdxdL5tU

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!

He is back where he belongs.
