For Bayern Munich, their loss to Frankfurt will cause them a lot in their title race should Bayern Leverkusen win Stuttgart in their match today.
It's quite a big goal difference, even from the start I was convinced the worst result was a draw. It seems that Tuchel's statement is correct, if Bayern's players take the match too easily. This resulted in their mental breakdown when the opponent made 2 goals. This saw the first half they lost by 3 goals. Even Frankfrut took the initiative to attack, they seemed to deliberately shock Munich by pressing above, so that Munich was not free to control the ball.
That scoreline is still beyond what I understand. Something feels off about Bayern Munich losing by such a wide margin. They appeared to be outside of Frankfurt's league. A team like that one would be expected to win, if not at least put up a fight. Football, though, is a volatile sport. We are reminded by times like this that even the greatest can buckle under duress. Bayern might use this game as a sobering reality check. This loss must be taken seriously, and they must grow from it in order to return stronger. If not, that would drastically threaten their goals, especially in the Champions League.
