"I do not need new players. I am pleased with this squad."
Bayern, who won a domestic double last term, begin their 2014-15 campaign at 18:00CET on Wednesday with a DFL-Supercup clash with Dortmund at Signal Iduna Park.
BVB, who won the curtain-raiser last term, finished as runners-up to Bayern in both the DFB-Pokal and the Bundesliga last time out.
