The former Bulgaria captain has played a bit-part role at Old Trafford this season making just 21 appearances in all competitions after falling behind Danny Welbeck in the pecking order.
Despite an admirable return of nine goals the 31-year-old knows his time with the Red Devils has come to an end just four years after his £30 million switch from Tottenham Hotspur.
Berbatov revealed that a United boss Sir Alex Ferguson broke a promise that he would play a prominent part for the Premier League runners-up and has accepted that his time at the club is up.
“We talked 10 times, he told me there would be a place for me but I stayed on the bench.” He told the Mirror.
“My time at Manchester United is running out. I no longer feel like a valuable part of this team. I think I did well in the few opportunities that I received.
“I am a little frustrated by the way this happened, I do not think I deserved it. But I have dignity and I stopped going to such meetings, it is clear that I’m leaving United. It’s obvious that I have to leave.
“I’m looking for a new place now. I know I can still play at the highest level.”
A return of 57 goals in 151 games will certainly attract clubs searching for a striker of European pedigree and it’s likely Ferguson would be willing to let Berbatov leave on the cheap as he looks to lighten the wage bill at Old Trafford this summer.
Ligue 1 billionaires PSG have been linked with a move for the laid back Bulgarian before whilst Galatasaray may reignite their interest during the close season.
