Wich player could help Real Madrid?

With the ups and downs Madrid currently has i just thought about where the problem really is. And i think it’s the lack of an real Striker. I thought of an good striker wich would play starter instead of starting Mbappe all the time. Of course one of the front three would have to leave and most likely it’s going to be Rodrygo even tho i like him very much. But after thinking of an realistic transfer that could happen i didn‘t really come to a player. What player comes to your minds?
