The injury misery has taken its toll on Bayern, and has jarred both the sporting and the overall statics of the Bavarians. Bayern’s 3-1 first leg defeat at FC Porto once again showed the vulnerability of the German champions against a team that is attacking and pressing virulently. Bayern got hassled and bullied, which led to two early mistakes by Xabi Alonso and Dante. Or, as Süddeutsche Zeitung put it: "Porto sent a young and persistent team to the quarterfinals who play a grueling and physical football". Porto has been "a conceivably unsuitable opponent for Bayern" in their present form. The Guardiola team couldn’t overcome Porto's assault and never recovered from the early goals of former Barcelona player Quaresma. Later, even the reliable Boateng made a mistake as Bayern struggled during the whole game. Only Thiago's goal gives the Bavarians some hope for the second leg.

Doctor Müller-Wohlfahrt resigns: "The relationship of trust has been damaged"

On Thursday evening another shocking incident occurred. The world-famous Dr. Hans-Wilhelm Müller-Wohlfahrt – who doesn't only treat footballers, but stars like Kobe Bryant and Usain Bolt too – along with all his medical team resigned with immediate effect from the Bavarian club. The well-decorated Müller-Wohlfahrt, who served as Bayern’s first team doctor for 38 years, announced his unexpected resignation via a press release. "After FC Bayern München's Champions League match against FC Porto, the medical staff was made, for inexplicable reasons, primarily responsible for the loss.” Furthermore, the press release noted that "the relationship of trust has been permanently damaged."

Bayern Munich was completely caught off guard by the resignation of Müller-Wohlfahrt and his team. Pep Guardiola held a press conference on Friday to clear up some things. Or to be more precise, he didn’t really clear up anything at all, since Bayern didn't want to talk about the issue. So people are left guessing what exactly happened in the dressing room at the Estádio do Dragão. "I respect Müller-Wohlfahrt’s decision and that is all I can say," Guardiola told the media and came fairly surprisingly to the defense of the doctors: "When a player is injured, then it is not the fault of the doctor. Injured is injured. We could have lost against Porto even if we had the injured players available. No one can guarantee that we would have won with our best eleven."

"The dispute of two very confident and proud men"

Still, the relationship between Pep and the doc everybody in Munich just called "Mull" was strained. "They spoke, but they did not understand each other," asserted Süddeutsche Zeitung and called the resignation a "gun salute", while highlighting "that Müller-Wohlfahrt first addressed the media without telling FC Bayern anything gives a hint of how dysfunctional the relationship must have been." Since Bayern didn't give an explanation, speculation was thriving such as Guardiola must be the cause of everything, since he already had differences in opinion over the treatment of Thiago.

"It's the dispute of two very confident and proud men who are not accustomed that somebody butts into their work," observed Süddeutsche. As a supposed "proof" of this dispute, a vine circulated on social media from Bayern's cup game against Leverkusen, claiming to show the Catalan coach sarcastically applauding Müller-Wohlfahrt on the bench after Benatia got injured. But there is no proof the doctor was even sitting on that bench. "That was just me being disappointed. It had nothing to do with Müller-Wohlfahrt," declared Guardiola during his press conference.

In fact, German newspapers revealed that at the Estádio do Dragão, it was chairman Karl-Heinz Rummenigge who was having an argument with Müller-Wohlfahrt over the huge injury list of Bayern, the main cause for the loss in Porto on Wednesday - an awful night that brought so much trouble. Trouble to Bayern and to Pep Guardiola.
