Yep, if Mbappe joins Real Madrid, it will be a perfect addition player for Real Madrid. Mbappe is a missing piece that Real Madrid looking for, he is the right player for Real Madrid striker (CF). With Mbappe, surely Real Madrid lineup will be perfect.
I don't know the continuation of this and indeed whether this is true or not because I searched for some of the same articles some opinions and some rumors made the difference because some said it was true and some said it was just a rumor.
But looking at the current conditions with Mbappe still there I think the rumors are true because in the end by looking at the ultimatum that PSG gave earlier and Mbappe still did not accept it then I think Mbappe will not be in the squad now which means that he extended the contract for one season this is true but on the other hand he must also be let go next season.
