DIMITAR BERBATOV faces a furious Spurs backlash after we snapped him signing a Manchester United shirt.

Livid Tottenham have already reported United to the Premier League for openly trying to lure him to Old Trafford.

The sight of their striker signing a Red Devils shirt will spark further outrage. An onlooker said: “I was gobsmacked when he took the shirt and signed it.

“He didn’t have any problems with it at all.

“If I was one of Berbatov’s team-mates or a fan, I’d be furious. It is incredibly disrespectful — he may as well have kissed the United badge.”

Berbatov, 27, signed the shirt at Sofia Airport as he set off for Bulgaria’s friendly in Bosnia-Herzegovina where he scored twice in a 2-1 win.

United have already bid £25million for Berbatov, who — as revealed exclusively by SunSport — handed in a transfer request on Saturday.

But Spurs are determined to hang on for £30m.

Tottenham legend and Sun columnist Jimmy Greaves said: “Signing the United shirt is certainly cheeky.

“He clearly wants to leave. If he doesn’t want to stay they should get rid of him.”

Spurs fan Bernie Kingsley said: “This brings back memories of when Paul Ince posed in a United shirt when he was still at West Ham.

“I just wish Spurs would sell him and get it all over with.”

It seems an agreement will be made within the week.
