The striker, who is currently on loan at Werder Bremen, has scored nine goals in the league so far this season but still thinks that he will have to move away from Munich in the summer.
"For Pep Guardiola, Petersen is certainly not the most important of personnel. But we are in contact with Matthias Sammer. When the three current strikers remain, for me it does not make sense in Munich," he said.
"Here I feel good and I know what I have. I feel that I am important here."
The 24-year-old signed for the Bavarians in 2011 from Energie Cottbus for 2.8 million euros.
