That being said, Mbappe is not the only available goal scorer in the market. Assuming it was last market window, I will say that there was shortage of good strikers because many of them were I active contracts but this time that the season is ended, some of them will be out of contract but even if they are still under contract, it will be easily negotiable.
Real Madrid should look the way of Victor Osimhen or Harry Kane for a long term replacement of Benzema.
Real Madrid will certainly want to get Osimhen in the team, and undoubtedly Mbape would be very interesting to them too, but PSG will definitely not let him go, especially since they have already lost Messi. But Napoli may not be able to keep on to Osimhen, because the player is very promising, and Napoli is not a financially strong enough team to keep him.
For sure Karim Benzema's departure this summer leaves a large hole in their attack. Among the names being linked to Real Madrid, I think Harry Kane is the perfect player. He is a proven goalscorer and is in the world-class bracket with Benzema. If he doesn’t extend with Tottenham, then they will lose Kane for nothing next year or if they do not sell him in the next two transfer windows. Also, it remains to be seen whether Kane would give serious consideration to leaving England for Spain.
