“I have just spoken with (general manager) Uli Hoeness and he is absolutely clear that selling Owen Hargreaves is not an issue,” said Bayern press officer Markus Horwick to PA Sport.

“He has recently signed a three-year contract extension and will be fulfilling that deal.”

Pressed on whether Bayern may alter their stance should a serious offer be received from Manchester United, Horwick reiterated that Hargreaves is not for sale.

“I think what Mr Hoeness says is enough to end any speculation,” he added.

“Owen Hargreaves will be staying with us for the remainder of the four years on his contract.”

Hargreaves, who starred at the World Cup, has admitted there was still time before the transfer window closes on August 31 to fill the hole at the base of United’s midfield.

On Wednesday, he confirmed in an interview with Sport Bild magazine that United had made an offer which he would struggle to turn down.

“I have certainly played more than 200 games for Bayern and that has been a very important part of my career, but now I have got to take the next step in my development,” said the 25-year-old.

“I have more of an affinity with the Premier League now than I ever have before.”

Hargreaves, who has previously snubbed the chance to play in England when Tottenham came knocking on his door, is hopeful the Bavarian club will listen to his request to leave.

He added: “The offer from Manchester United is fantastic. Mr Hoeness knows what an opportunity this is for me.”

However, after losing Michael Ballack to Chelsea this summer, Bayern are not prepared to let another key midfielder go.

Coach Felix Magath intends to get the best of Hargreaves in a Bayern shirt this season.

“I am not planning to get rid of any players, particularly not Hargreaves - it has never been an issue,” he said after training on Wednesday.
