Bayern Munich ace told to forget Man Utd

Bayern Munich ace Oliver Kahn insists that Owen Hargreaves has to be professional about his Man Utd situation.

Hargreaves signed a new contract with the club not long ago but is now desperate for a move to Man Utd.

Kahn insists you cannot just sign a new three or four year contract and then disappear at the first opportunity.

Man Utd are being forced to drop their interest in the Bayern Munich ace and Fergie will be disappointed.

"You cannot just sign a new three or four year contract and then disappear at the first opportunity," said Kahn to DSF television.

"You have got to be professional, perform as best you can, show a reaction and give it 100%.

"After all, football is not a concert in which you get to pick your favourite songs."
