Mario Gotze's future at Bayern Munich remains a mystery after he once again failed to rule out leaving the record German champions this summer.

Speaking after Bayern won the Audi Cup with a 1-0 win over Real Madrid on Wednesday night, Gotze only revised part of his remarks from 24 hours earlier, when he was particularly coy about what the future held, saying he'd had two difficult years with the club.

He set the record straight only that he has no problem with Pep Guardiola after suggesting on Thursday that his goal against AC Milan might prompt the Catalan to talk to him more often.

All the rest about not being sure where he will be playing next season was repeated on Wednesday, although he hinted it would not necessarily be his decision to leave.

"I'm very, very happy here," he told ZDF television. "From my side, I can say that I'm happy to play here, with these fans, with this club – it's a fantastic job.

"I'm very happy with everything around me and with the things that happen here, but there are always two sides to everything."

Later in the Allianz Arena mixed zone, the 23-year-old continued to leave the door open to a transfer among persisting rumours that Italian champions Juventus are preparing a bid.

"Whatever happens, there's no question that I'm happy here. As for the rest we'll just have to wait and see, like I said on Tuesday," he told reporters, quotes sport1.de.
