Owen Hargreaves will reportedly hold a news conference today to confirm that he wants to leave Bayern Munich.
The England midfielder is expected to criticise the German club for standing in the way of his move to Manchester United.
Relations between the two clubs soured on Tuesday when Bayern threatened to report United for breaching Fifa rules with their pursuit of Hargreaves.
United are thought to be prepared to offer up to £17m for Hargreaves, althpugh Bayern are reluctant to sell another midfielder following the sale of Michael Ballack to Chelsea earlier in the summer.
But Bayern general manager Uli Hoeness said: “Bayern Munich will never be taken for a ride and become weak at the knees as soon as a certain level of money is mentioned.”
