Veron, now 41 and retired, played for United between 2001 and 2003, having two mixed seasons at Old Trafford not without their highlights.
Yet he was lured away amid the Roman Abramovich revolution at Chelsea, with United deciding the chance to recoup a large portion of the transfer fee they paid for him was too good to refuse.
Veron has admitted that he never should have left Old Trafford. He said: "Sometimes I played with Scholes and Keane, sometimes in a 4-4-2 with Dwight Yorke and Andy Cole. The system varied, but I should have stayed at United and not left.”
If his time at United was mixed, then his Chelsea tenure was far worse. He struggled with injury in his first season at Stamford Bridge and was then sent out on loan back to Italy and then in Argentina before departing permanently.
Fortunately for the considerably talented midfielder, his career got back on track at hometown club Estudiantes, leading them to the Copa Libertadores, South America's equivalent of the Champions League.
He even regained a call up to Argentina's national squad, featuring in World Cup 2010, and while his career at United was one of unfulfilled potential, he will be remembered as one of the most gifted midfielders of his generation.
