Bayern Munich CEO Karl-Heinz Rummenigge says any players unhappy at the club should seek talks with him to discuss their future, amid speculation Thomas Mueller is set for a move to Manchester United.
Following the fallout of the 4-0 Champions League thrashing by Real Madrid last month, several Bayern players were linked with a move away from the Allianz Arena.
On Friday, Javi Martinez was linked with a switch to Barcelona by kicker, while Mueller was also among those players named as possible candidates to leave the club.
According to kicker, Mueller could consider joining United should Louis van Gaal be made the next manager at Old Trafford.
But Rummenigge told Bild: "Should anyone not be happy at FC Bayern Munich he should come to my office. Then we'd need to talk about it."
Confronted with the speculation, Mueller refused to discuss his future with Bild.
"I won't comment on any rumours," he said.
And when directly questioned about the United link, Mueller replied in English: "No comment."
Despite Bayern officials reiterating several times that Mario Mandzukic will be offered a new contract, kicker reports that the club have yet to stay true to their word.
The attacker could become surplus to requirements by the imminent arrival of Borussia Dortmund's Robert Lewandowski, who is set to join the German champions on a free transfer this summer. With 18 goals each, both players currently are joint-top in the Bundesliga scoring charts.
Mandzukic was not allowed to add to his tally at Hamburg on Saturday, where he sat on the bench for the full 90 minutes.
Instead of the former Wolfsburg man, veteran attacker Claudio Pizarro was brought on for the final 20 minutes, getting in amongst the goals with an overhead kick.
After the game, Mandzukic refused to commit himself to Bayern.
"Soon, you will all find out," he was quoted as saying by kicker.
Elsewhere, on Friday, Mario Goetze voiced his discontent about his status at the Bundesliga champions.
"Of course, I am not happy. But I will continue to step on the gas. I hope that I will get the trust of the coach soon," he told Bild.
On Saturday, Goetze started for Bayern and put two goals past Hamburg goalkeeper Rene Adler. The former Borussia Dortmund player has now scored 10 goals in his debut campaign at the Allianz Arena, equalling his record tally from his final season at BVB.
"That was a good reaction from him. We are glad to have him. Should he have made a statement in the sense that he is not happy when he does not play, that's part of it all. That's OK," Bayern sporting director Matthias Sammer told Welt.
Bayern centre-back Dante added: "Mario is a phenomenon, the FC Bayern future is his. He is an intelligent lad and has a good attitude. With his technique he could as well be from Brazil."
