Tuchel has been pushing bayern so fast. Bayern performed so badly and it's almost trophyless last season. Tuchel is still thinking so hard about how to build a proper squad. bayern just need to buy a reliable striker. Kane is on his way, but Bayern is struggling to negotiate a lower transfer fee. Spurs set a deadline for the transfer to be completed by August 11th. bayern really needs a good striker right now.
Bayern Munich was just struggling and played so bad because there was all that problems around the managment and the coach Nagelsmann.
This have got an effect on the squad and the team , so there was not much that a new coach in this case tuchel can do in a few days and weeks.
A part from good result against liverpool, bayern needs to make sure it will have a better striker. Gnabry was good but it's not enough to help bayern to have bigger chance in winning UCL. Kane's stat was far better compared with gnabry.
Kane and Gnabry are different players , both are very good and they can change a game.
Gnabry is still good and if Bayern Munich will not be getting Kane he can show what he can do.
