Bayern Munich president Karl-Heinz Rummenigge has revealed they did turn down a huge offer for Manchester United target Thomas Muller in the summer, but indicated the club could be powerless to prevent a lucrative move to the Premier League in the future.
Muller, 25, has been a target of Louis van Gaal since the Dutchman arrived in English football, attempting to sign the player in his first summer in charge at Old Trafford.
This past summer, the club returned with an extraordinary offer of €100m (£70m, $111m) for the Germany international, according to Bild, only for Rummenigge to later tell Kicker there is "no price" for the player.
While he did not disclose the name of the team who launched it, the Bayern president did confirm an offer that would have tested the resolve of many, but insisted Bayern were never tempted to cash in.
"I'm talking about figures which were very high indeed," he told Suddeutsche Zeitung. "If I were a bank manager then I would have had to accept it, but as a football club we allowed ourselves to close the door on it, and this door is remaining closed. I can promise that to everybody."
However, Rummenigge did concede that the Premier League's growing wealth could make it increasingly harder for even Bayern to continue to resist offers for their best players.
"One thing is for certain, in view of the increased television money in England things are not going to get any easier for Bayern in future," he said.
Rummenigge's comments followed a similar line to those of Monaco vice-president Vadim Vasilyev. The Ligue 1 club sold 19-year-old forward Anthony Martial to Manchester United on transfer deadline day with Vasilyev later admitting there is little clubs can do when faced with the financial weight of Premier League sides.
"It's the price of Luis Suarez or Neymar – the best players in the world," Vasilyev said of the reported £36m United paid for Martial. "Right now English football is on a different financial level and if Manchester United decides to buy somebody, it's very hard to stop them."
