Manchester United hero Dimitar Berbatov fears his old club are facing years in the wilderness.

Berbatov has fired a warning to his former club.

He told Betfair: “It is frustrating and difficult for me to admit that United are so far behind Manchester City and Liverpool.

“When it comes to playing the game, you can see how confident and calm on the ball they both are, they know how to play and sometimes United don't have that and they suffer because of that.

“I hope that Manchester United don't end up like Liverpool and wait at least 29 years for the title. Six years is a long time to wait to win a title for a team like Manchester United."
