Bayern Munich striker Thomas Muller lost his rag with coach Pep Guardiola during defeat at Barcelona.

Bayern lost 3-0 in the first-leg of their Champions League semifinal at the Nou Camp.

Guardiola hooked Muller during the game, much to the frustration of the striker.

Marca reports TV cameras caught Muller blasting his coach, with a German lip reader claiming he stated: "You're going to end this s*** already?!!"
