The Uruguayan, due to return to the Theatre of Dreams for the first time in next month's Legends of the North charity fixture with Liverpool, has previously discussed moves to the Reds with David De Gea and Facundo Pellistri.
He was a team-mate of our no.1 at Atletico Madrid and managed Pellistri, currently on loan with Alaves, at Penarol.
There is no doubt in Diego's mind that United continue to represent the perfect choice for anyone targeted during the upcoming transfer windows.
De Gea broke into the Atletico team as a youngster when Forlan was up front for the Spanish side and there were discussions between the pair when Sir Alex Ferguson attempted to make the rookie keeper his replacement for the retiring Edwin van der Sar.
