I've heard some rumors that Thomas Tuchel is eyeing several players for Bayern Munich's attack line but he hasn't made any offers yet so we don't know what steps Tuchel will take in the future as the transfer season is almost over.
Yes, if some of the players are really taken and can collaborate to play with Mane it will create an attack game that is effective enough to produce goals but getting new players to collaborate well with old players also takes time so it is a challenge for Tuchel in the future.
Bayern Munich have a good attacking system and with good growth of Musiala, they will have better attacking and creativeness in a new season. They still lack of a good central striker as Choupo-Moting can not replace Lewandowski. He is at a lower level than Lewandowski and Bayern are looking for a new striker.
A most common rumor about Bayern Munich transfer recent weeks is about Harry Kane. Kane will give Bayern Munich many options for their attacking system and will be a good striker for them. I believe he is the best choice for Bayern Munich too because he is not too expensive like Mbappe and Haaland, has good quality and he is not too old. Signing with a world class striker and can use him in next 4 years at highest level, it is a very promising transfer for Bayern Munich.
