Speaking after the game, Muller said: "I'm still fully in work mode now. It doesn't feel much different from before the game when we tried, and I also tried, to just get one round further.
"In the end, maybe we deserved more. But in football when you have these tight matches, it's sometimes a coin flip. And, yes, we lost it.
"Of course, I am aware that this was my last game, and I will see what goes through my head in the coming days.
"At the moment, I'm not in the mood to share my deeper thoughts about my career. We lost a big fight, a very important game for us."
