Bayern Munich duo David Alaba and Rafinha will both miss the start of the Bundesliga season after the pair picked up injuries in Friday's 3-2 friendly defeat to Napoli.

Alaba, 20, picked up a stress fracture in his left foot and has been ruled out for two months, while Rafinha, 26, pulled ligaments in his ankle, and is expected to be out for five weeks.

Last season's Champions League finalists are currently touring the Far East as part of their preparations for the new season.

Bayern open up their league campaign against Greuther Furth on August 24.
