I don't know why Bayern Munich management insists that they will part away with Tuchel at the end of the season, even after several coaches have rejected their offer. I don't think Tuchel was responsible for Bayern Munich's bad performance this season. However, Bayern Munich's performance this season has been amazing, but there is no consistency in their games. Many people think that Tuchel was responsible for the issues going on with Bayern Munich this season. But with Tuchel Bayern Munich reaching the Champions League semifinal, even in the Bundesliga league, they are still in the second position.
In my opinion, Tuchel needs more seasons to get used to the club since there's a lot of pressure on him this season. Though the Bundesliga is not a tough league, even though Bayern Munich appoints a new head coach next season, I don't think it will be easy to get used to the club. Let's see what will happen after the season ends because I don't think the management will change their decision for Tuchel to remain in the league.
Consistency was the only challenge Bayern Munich actually encountered this season but they were able to still get to finish at the second positions on the table which I think is a way of showing that they didn't have a really bad performance this season but then I don't know why the management still seem to think it's very okay to just let go of tuchel because they think he's the reason for them not winning the trophy this season.
One thing they should know Is that changing of coach has got its effect it may get on the team aswell because they will need more time again to start adjusting to the tactics of the new Coach and even the coach getting use to the players and this may take them almost half of the season to get all of this done but with tuchel, they have gotten a pattern with which they can start and definitely hope to get the game stabilized even before the season gets half way as the players are already used to his tactics and his strategies having been with him awhile so it's possible if given the chance he could do better by next season.
Amidst all that really happened they were able to achieve a few heights of which I think should be a basis for them to give him some grace, their performance at the champions league and even in their domestic league are all summed up to been a better or considerable performance worthy of giving a chance but it just seem like the management of Bayern Munich is just not patient enough to wait long enough.
