Since Mbappe refused to extend his contract with PSG and since the club president Al Khalifi said it clearly that Mbappe has to renew the contract or leave the club in two weeks then I assume Mbappe will join Real Madrid by the end of the transfer window. At worst he will be sanctioned and will be in the benches the next season so he might accept to leave in the winter transfer window.
Real Madrid has to find a temporary solution only concerning that spot.
Real madrid has found a solution by taking joselu as a temporary striker for real madrid. Mbappe is not an important anymore with real madrid. His attitude makes madrid feel so bad with him. Madrid think for twice before try to sign him as a new player.
Mbappe is full with trick to manipulate its club. Madrid must be careful with mbappe's personality once the club wanna sign him as a new striker. PSG faced so many internal problems due to the bad personality.
Ancelotti tries to find a good striker to be bought during the summer transfer season. The name of the striker that Ancelotti is going to buy might be revealed soon. Ancelotti considered Vlahovic as a successor for Benzema, but this rumor turned out to be false..
Madrid needs time to find the best striker that gonna fit to the club. It won't be an easy task to be done.
Benzema leaving the club has left big void in the club and that space is going to cost them alot if they don't find a suitable replacement and mbappe would have been a perfect fit but like you said the guys has too many issue and his current club doesn't even want him to be sold and thats also same fit with the second player they also wanted to sign which the englang national harry kane. Harry kane and Madrid has been linked for some time now but always seem hard for Tottenham to let the striker go and same thing again has happen this transfer window, I just hope Madrid finds a suitable striker for that bemzema position.
