Arsenal and Liverpool have joined Manchester United in an attempt to prise Thomas Muller away from Bayern Munich, reports in Germany suggest.
The 24-year-old is reportedly open to the idea of leaving the Allianz Arena this summer if he has the chance to link up with former manager Louis van Gaal, who is widely expected to be named the new manager at Old Trafford.
In response, Muller, who has been valued at £35m, was forced to deny suggestions he was ready to part ways with boyhood club Bayern but did admit that he was unable to make any guarantees regarding his long term future.
Respected German magazine Kicker have intensified rumours that Muller could leave. The reports suggest the forward is open to remaining at the club where he has spent his entire career but has grown disenchanted with Pep Guardiola's lack of faith in him during the club's biggest games this season.
Muller did not compete any of the games against Real Madrid and Manchester United in the quarter-final and semi-final stages of the Champions League while he had to settle for cameo appearances off the bench against Arsenal in the first knock out round. The German international was also left on the bench for Bundesliga clashes against Bayern's closest domestic rivals in Borussia Dortmund and Schalke.
Kicker suggest Muller's discontent with the current situation has caught the attention of Arsenal and Liverpool who are aware that this may be their best possible opportunity to snare the forward away from Munich.
Meanwhile, Bayern legend Franz Beckenbauer warned the club that they must do everything in their power to ensure Muller does not leave, but admits should the player hand in a transfer request then the matter may be out of their hands.
"Normally I would say we should not stop people who want to move on," Beckenbauer said. "But for Thomas Muller, FC Bayern should fight to win him over, if he really has plans to leave.
"He is the original Bavarian player, and the fans identify with him. I don't see any reason why he should be unhappy in Munich.
"He has had more games on the bench this season, and has not started in the knock tout games in the Champions League, but under Pep Guardiola, he is a very highly respected player.
"So we must do everything to keep him. We should look for another solution, and consider letting him go, only if he categorically states that he does not want to stay."
