The Bulgarian's future at Old Trafford remains in constant doubt after falling down the pecking orders in Sir Alex Ferguson's plans this season.
There have been strong speculation linking him with a move out of the club this January - although Ferguson has recently indicated his desire to extend his contract for a year.
But that has been seen by many as a ploy to protect the 30-year-old's value.
Now according to talkSPORT, Bayern have approached United over a possible deal to sign the out-of-favour striker at the end of this season.
It is highly likely that the Red Devils will undergo a major overhaul in the summer as Ferguson looks to bring in fresh blood - with Berbatov likely to be among those to head out.
