Bayern Munich and Real Madrid are both lacking an important thing in their squad now which is a striker. They both have strikers in their squads technically of course but they don't have a reliable one for especially the Champions League. Bayern Munich's performance was quite inadequate for this reason last season as well.
Real Madrid have also lost Benzema and loaned Joselu. But Joselu has surely been brought as a replacement for their future main striker. But they have still not made up their mind on a target yet. There are only rumours on the internet.
But I believe both teams will manage to solve their striker problem before this transfer window closes. But I can't be confident about the time period before the season starts officially.
Bayern Munich Must be aware of this. Because it's true that Bayern munich weak point is the front line because they don't have such a quality centre-forward to score goals. Bayern munich lost to Manchester city in a friendly match where the final result was 1-2 for Manchester city's victory. So Tuchel must see their weaknesses after they were defeated by Manchester city.
One of the big efforts made by Bayern Munich was to bring in a sticker in this transfer window, which never worked. But bayern munich bid for Harry kane is still there if Bayern munich is able to increase their bid on the new proposal most likely Bayern munich can overcome weaknesses in the front line if they manage to get harry kane. For real madrid they have names of attackers they want to bring in like Mbappe and Vlahovic.
