Ronaldo to consider three clubs for his retirement     Reuters

Cristiano Ronaldo has once again admitted he may end his career at Manchester United.

The Portuguese international collected the Uefa Best Player in Europe award on Thursday to accompany his 2013 Ballon d'Or and Champions League winner's medal following Real Madrid's success last term.

Although there is likely to be plenty more success on the horizon for him at the Santiago Bernabeu, Ronaldo has often pondered what his next move will be.

Speaking to Portuguese network TVI, Ronaldo discussed his future in the game, revealing that he intends to keep playing at the highest level until he is 36.

A return to United, whom he left for Real Madrid in 2009, is on the forward's mind, although he will consider two other options when the time comes.

"I could say that I would like to end my career at Real Madrid, which is the best club in the world," Ronaldo was quoted as saying by O Jogo.

"Or Manchester United because I have a special history with the club. Or maybe at Sporting, who gave me my foundation."

After graduating from Sporting's famed youth academy, Manchester United swooped for an 18-year-old Ronaldo in 2003. During his six year spell at Old Trafford he lifted three Premier League titles, one FA Cup and a Champions League trophy in 2008. Under the guidance of Sir Alex Ferguson he won his first Ballon d'Or in the same year.

The forward has previously talked about a possible return to Manchester and was heavily linked with a move back to Old Trafford last summer, until he signed a deal the following September which keeps him at the Bernabeu until 2018.

Former United boss David Moyes recently revealed the club was very keen to bring the player back last year having also looked into the possibility of signing Cesc Fabregas and Gareth Bale, now at Chelsea and Real Madrid respectively.

"It's been well documented that we wanted Fabregas, Bale and Ronaldo. There was talk of Ronaldo when I first arrived. We were close to getting a couple of major names. I'm not getting in a blame game here but things just didn't materialise," Moyes told the Daily Mail.
