Since being handled by Tuchel, Bayern Munich's condition has not been stable. Yes I think the Bavarian's chances in the Champions League are getting tougher because they are 3-0 behind Manchester City.
Similar conditions also occur in the domestic league, they are surprisingly also eliminated in the DFB Pokal. Now Bayern only has a chance in the Bundesliga, but if you look at the standings table, Tuchel needs to work hard to maintain his top position. The draw that was obtained against Hoffenheim is certainly not something to be proud of, because the gap with Dortmund who is in second place is only two points left.
The performance of Bayern Munich was not stable before Thomas Tuchel became their new coach too. That was the main reason, why Julian Nagelsmann was fired. Of course now it seems like that change does not have any effect, but Thomas Tuchel is the last one to blame for that. In such a short amount of time he just can not really learn a new system or playstyle to the team. He has to work with what was there before. Even though Bayern Munich showed a pretty weak performance on Saturday against Hoffenheim it still feels like Borussia Dortmund was the big loser of this past matchday because they received the equalizer so late.
