After a charity match in Monaco, Ferguson was asked by French television whether Berbatov might make a move to Ligue 1.
"Yes, he might," he replied. "That's possible."
The Parisian club have recently been the subject of a takeover bid by a wealthy Qatari investment company, and may look to make Berbatov the first of several marquee signings as they look to push PSG towards the forefront of European football.
Berbatov had his strongest year yet with United in 2010-2011, finishing the season as the Premier League's top scorer. Despite this, he couldn't even earn a spot on the bench in the Champions League final against Barcelona.
With Javier Hernandez emerging as an outstanding prospect last year, Michael Owen being handed another contract and Danny Welbeck showing good form in the preseason, Berbatov is seemingly surplus to requirements.
£20 million would represent an excellent piece of business for United given Berbatov's age (30) and the fact that Berbatov has only a year left on his contract.
Perhaps more importantly, it would also free up funds for a move for Inter's Wesley Sneijder, a player United have been consistently linked with all summer.
What do you think—are Welbeck, Owen and Chicarito good enough to replace Berbatov?
