Monday morning see's some interesting transfer reports regarding United's manager Sir Alex Ferguson, who is apparently showing interest in Real Madrid and former Manchester United player Cristiano Ronaldo, along with Barcelona's Cesc Fabregas.

Former Arsenal midfielder Fabregas, is unhappy at being left on the bench for the La Liga giants thus far this season and with the competition staying strong amongst the ranks, rumours are speculating that the Spanish international is set for a return to the Premier League, with Manchester United and Arsenal leading the way, according to The Guardian.

Also being reported via the same source, another unhappy La Liga star Cristiano Ronaldo is also on United's radar, with Ferguson apparently asking the club owners to go all out in an attempt to bring the Portugal captain back to Old Trafford, where he made his name previously. 

Of course, there is also interest from Roman Abramovich's Chelsea who are in for the unsettled forward in January. He won't come cheap though and whether United can compete with Chelsea for the players €100m release clause, remains to be known.

Ronaldo featured for United during the beginning of his career and really broke onto the scene, he scored 118 goals in 292 appearances for the Manchester club in just under 6 years. He became a cult hero in the stands and United supporters would surely welcome the prospect of having their one time hero featuring in the red shirt yet again. 

27-year-old Ronaldo has had a colourful career that's never been short of controversy. Seemingly continuing the craze this season, he has been involved in apparent fall outs with certain members of the Madrid backroom staff and has become 'sad' at the club, thus alerting the big name Premier League clubs with Chelsea and United leading the chase.
