Bayern Munich should of course make a transfer. Last year's squad wasn't bad, but transfers are still needed. I think Harry Kane should definitely be on the team. A striker is needed for Bayern to achieve significant success in European tournaments. Harry Kane is a striker who can give them what they need. Let's see which players they will add to the team?
Bayern Munich in the hands of Tuchel seems to really need a big overhaul for next season. Some of the players they have targeted in the transfer window are quite good, especially Harry Kane who is believed to be the right sticker for them for next season. But one of the things that was very difficult for Bayern Munich to get Harry Kane because the price clause that Tottenham wanted was quite high.
Tuchel will bring several new players to the depths of the Bayern Munich team, especially they have got Kim from Napoli. And I think they are trying to convince Tottenham to let Harry Kane go in a second bid later.
We can't be sure about Bayern Munich in the next season at all.
Bayern Munich had an unstable performance in the last season and that's why they hired Tuchel to have a better performance, especially with the experience Tuchel has in the Champions League but still, we didn't see much from Bayern Munich with Tuchel.
There is still a chance for Bayern Munich to have an unstable performance in the next season and the same problems the had in the next season, in this case, there is even a high chance for Tuchel to get fired.
