There was once a time that Cristiano Ronaldo looked like he would finish his career in Spain with Real Madrid. However, it has now been revealed that all is not good with Ronaldo and he may seek a move away from Spain.
This has led to speculation that the player may seek a return to the Premier League. The obvious destination would be a return to Manchester United.
I think Ronaldo realizes that it was really Manchester United that made him the player that he is today and will remember his spell with the club fondly. He also must have the utmost respect for the talents of Sir Alex Ferguson.
However, it remains to be seen if Ronaldo still feels he has a point to prove at Old Trafford.
I think most people would agree that Manchester United acquired some real quality in the summer transfer window. The signing of Robin Van Persie was a superb piece of business and it is the sort of signing that could swing the Premier League title back to United.
Ronaldo may well fancy the opportunity to join the Dutchman and Wayne Rooney in a frightening-looking front three.
There are not a lot of clubs that a player can go to that are as big as Manchester United. It is a club that people always believe can win titles and continue to be successful. That is due, in no small part, to the brilliance of Sir Alex Ferguson.
Ronaldo knows what it is like to win league titles with Manchester United, but that doesn't mean he won't have the motivation to do it again. If the player does leave Real, then he will want to go somewhere he can continue to win. United can give him that platform in all competitions.
When a player moves to a new league in a different country, it is unclear if they will be as good as they were. However, Ronaldo has already proved what he can do in the Premier League, so he knows switching will not be a problem.
But it remains to be seen if Sir Alex Ferguson will welcome him back.
