"I will not respond to these rumours. There is so much speculation but I can only deal with football. I still have two years left on my contract so why would I want to leave? It's all about performance on the field and in the last games I have shown that I can contribute here in Bavaria.
"I am solely focused on Bayern. We want to win the title (Champions League) on May 25."
