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.
