The 23-year-old, who has scored 15 goals this season, is expected to be in the Bayern team for their last-16 Champions League clash against Arsenal on Tuesday.
"I'm rooted here and would only have to challenge that stance if I am deteriorating," he told Kicker.
"I know that I can play in the middle, on the right or up front. I look at these three positions as me being a reinforcement for Bayern. And I want to play there in important games.
"I see an extremely bright future here. I feel support at Bayern now, and do not feel that I am on probation games the whole time, and will be dropped at the slightest wobble."
