Although Bayern Munich must struggle to face match after match in the Bundesliga, but that will not stop Nagelsmaan from tweaking his strategy game by game even without having a main striker as a Target Man.
So far, they are starting to find their form even without a definite centre-forward, but Nagelsmann is still capable despite only rotating his players. and it sometimes works quite well especially in the champions league.
they still have a big chance in the Bundesliga, even without signing a newcomer in the next winter transfer window. but it's hard if Bayern really don't bring in new players in the transfer market later.
I'm sure Bayern Munich have targeted several players for them to bring in later.
