Madrid knows the huge cost of buying a world class player like Kylian Mbappe and that's why they want him to join the club as a free agent by next summer. The striking role of the club that was left vacuum with the departure of their former club captain will definitely affect the team's performance if not properly replaced. So I think they should get a temporary striker that'll fill that role for the new season before the supposed arrival of Mbappe by next summer
The possibility of Mbappe coming to Real Madrid is very high because Mbappe has expressed many times that he doesn't want to continue with PSG, and Real Madrid is the club he's very interested in and will join when his contract expires. Real Madrid is targeting many contracts, and among them, I see Harry Kean as the most reasonable option right now for Real Madrid.
The reason why Real Madrid lose against Juventus is Real Madrid use a strategy where it depend on Bellingham as an attacking midfielder. They're more comfortable when the midfielder backing up other midfielder and working together.
But it's clear there are so many chances in Real Madrid, but their strikers weren't able to maximize it.
Real Madrid is testing Bellingham with this position, and I believe everything is just beginning with him, so it's not bad to have some losing matches. He needs more time to adapt and adjust his playing because he's still very young, and there's so much potential to develop.
