But the fact that he failed and that means he cannot bring Bayern to what it should be where the 11-season trophy that has been defended is just lost because of Tuchel's inability to give the best at Bayern is an undeniable fact.
When talking about the coach whether he is great or not indeed in the previous club he was a coach whose quality was above average but for Bayern it was still bad and a mistake.
Regardless of whether it is because the leadership style does not fit the philosophy that Bayern has or indeed because it is purely from Leverkusen who are extraordinary this season, it still cannot be used as an excuse for Tuchel now because he is a failure for Bayern.
In terms of Bayern failure to maintain their dominance this season, I'm more inclined to think that it's purely due to Leverkusen impressive performance, we can't blame Tuchel entirely. I think if Tuchel can bring Bayern to collect more than 71 points at the end of the season, it means that statistically Tuchel is still better than the previous coach. Last season Bayern won the trophy with 71 points, currently with 66 points and 4 matches remaining, Tuchel has the opportunity to take Bayern beyond last season points tally.
So with these facts, I think it is reasonable to assume that their failure this season was purely because Leverkusen appeared unbeatable. The luck of a team like Leverkusen will be very difficult to control, not only in the Bundesliga, we also know that Leverkusen is also very consistent in the Europa League and DFB Pokal. Luck is on the side of Xabi fleet, where no team has been able to beat them.
The ups and downs in performance that have befallen Bayern this season are not entirely acceptable, especially when they lose to mediocre clubs, it makes us surprised because they are not performing as usual. But on the other hand, Tuchel has been able to bring his fleet to the semifinals of the current Champions League, which is also a success, where last season they only reached the quarter finals.
