Portuguese left Old Trafford for the Bernabeu in the summer of 2009.
Manchester United are said to be hopeful that Real Madrid playmaker Cristiano Ronaldo would like to end his career at Old Trafford, according to reports in the Observer.
The coveted Portugal international left the Red Devils to join los Blancos in a world-record transfer worth £80 million in June 2009, and in the intervening four-year period the 28-year-old has gone on to score score an incredible 201 goals in just 200 matches in total at the Santiago Bernabeu, including an equally impressive 146 strikes in only 136 Liga outings for the Spaniards.
However, the Premier League champions are understood to have recently received positive signals from Ronaldo’s camp that he would now like to play the final three or four years of his playing career back in the north west, with a possible deal to bring the Portuguese back to the Premier League set for next summer.
That, though, may depend on Madrid, who are currently renegotiating Ronaldo’s present contract in the Spanish capital, which now only runs until June 30 2015, with the Red Devils fully aware of just how important the player is to their commercial successes throughout the world.
And there is also a fear at United that Ronaldo could simply be using these rumours of a return to Old Trafford as a means of getting a better financial deal out of Madrid in his current discussions with the club over his new contract, although equally they know that they have to do all they can to try and persuade the forward to re-join them.
