Honestly people calling this sacking moronic or irrational just don't know much about the current football at Bayern. To say that the sacking is just based on last nights game is nowhere near true. The fans were always critical, the media was always critical, the players didn't buy Carlo's methods. Bayern have only regressed under Ancelotti and instead of waiting till 2 years of this have sucked all the stuff from the Heynckes and Pep years out of Bayern, they decided to be proactive and to start rebuilding asap. Bayern know they need to do transitioning and they want to introduce younger players again as well. Carlo not only isn't usually the greatest with developing young players, he's also completely lost the dressing room's old players at Bayern. Robben, Ribery, Hummels, Müller, and Lewandowski have all been critical in front of the press recently. Something was wrong, and the chance for Carlo to be sacked was near for the last month. The PSG game was just the opportunity to find a reason to sack him. He wasn't developing them at all, and they were just turning into a dysfunctional, unhappy team.
