What Bayern Munich is experiencing this season is related to Tuchel's coaching because everyone can probably compare Bayern Munich's performance last season with the performance shown by Bayern Munich this season. So Bayern Munich has the possibility of not getting any big trophies this season and also including small trophies in their own local league such as the DFL Super Cup. This is certainly very sad for Bayern Munich because previously Bayern Munich was always a candidate to win, both in the Champions League and in the Bundesliga.
Actually I see Kloop also suitable if he goes to Bayern Munich. But his statement about his future seems to have been answered. So that seems unlikely to happen. Instead of Xabi I think Zidane could be another alternative. Because I read he is ready to work again at the moment.
Bayern Munich's chances in the UCL are still very big. They only lost 0-1 to Lazio in leg 1. Furthermore, they have many opportunities because of leg 2 in Germany. I am very sure they are able to qualify for the last 8.
