The Austrian defender has opted against signing a new contract at Bayern Munich, with his current terms set to expire in 2021, meaning that he could soon be on the move.
The long-serving left-back has been linked with a host of Europe's top clubs, but insists he wants to stay at Bayern and has not thought about a move.
"I'm happy to be here, I'm happy to be part of the team," he said.
"I really enjoy playing for Bayern Munich and I'm not worried about my future, I've not thought about other alternatives. I've not been in touch with any other teams or clubs.
"Bayern will always be my first club I would contact and that's why I've never really thought about where to transfer if I did."
