It is going to be very disappointing for Bayern Munich to lose their title chance this easy. But they totally deserve that after this huge loss against Leipzig home. They just gave up on the title before their supporters in Allianz Arena. There is nothing more humiliating for them I guess. But I believe it would be very unfair to judge Tuchel harshly for this. He hasn't even managed the team for a long time period.
When they were ahead in the first half it seemed like they had had enough, the attack started to loosen, I saw how the TV screen highlighted how happy Oliver Khan was for the goal, but after that there was nothing dangerous about their attack, even I didn't really like what it was done by Musia who seemed to want to score a goal without giving his friends a chance, so you could say they deserved the defeat because they played without good coordination. The second half was a disaster for Bayern Munich, after Leipzig's first goal and two penalty prizes made them worse off and trying to catch up was too late because Leipzig had played very comfortably through counter-attacks and could be said to be quite dangerous.
Nagelsmann brought things to this point mostly as you already know. It would be the funniest action to take for Bayern Munich if they sack Tuchel only a short time after he joined. I know that it is very annoying for Bayern Munich fans. But I think that this is totally related to the players rather than Tuchel. They just don't play like they believe in themselves completely sometimes.
Tuchel took over a team at the wrong time, although this kind of result can still happen with their old coach, because the problem is not an inexperienced coach but players who are not playing with passion to be able to win the league title this season, it's a shame they will ended the season without a title.
Dortmund will play today, they also missed several chances if this time they do the same thing so how happy the Bayern fans are, although I'm not sure they will repeat the same mistake by wasting this golden opportunity, so the decider will occur in the final match next week.
These things have been dropping down the team into a worse place. Plus Bayern Munich absolutely need a striker like Lewandowski immediately.
Sadio Mane hasn't been playing well after injury so he's been on the bench more often and Gnabry isn't as sharp as Lewandowski, so they really need a new striker for next season
Against Augsburg, Dortmund will try to attack because the team they are facing also still needs a win. If Dortmund is off guard, then a golden opportunity will be wasted and this should not have happened because the last match against Mainz will be a tougher game for Dortmund later.
