With Mbappe's transfer alone it is enough that Real Madrid will not bid for players with higher prices including Julian Alvarez who has a price of 90M according to transfermakrt.
Some of the main squad is now more than enough with the addition of Mbappe perhaps he will be in the center forward position while the left and right wings will be filled by Vini and Rodrygo.
Even Joselu is not an expensive player maybe Real Madrid can throw him away at any time, it's just that now Joselu is still a little needed for substitutes sometimes he also has the luck to always score goals.
If Mbape had accepted the offer presented in the first phase before he change his mind, he would be among the highest paid in Real Madrid right now if not even highest but he messed up and jeopardize his reputation for PSG which was understandable but as soon as the main guy became the stranger among the elite and there was no Champions League future, he decide to live and the best place to have it quicker is Real Madrid but now that Real Madrid is good to go without him, he either join with moderate payment or go elsewhere where he might never win Champions League.
There is going to be a lot of pressure coming from the fans now but I'm sure the forward will do fine since Tony Kroos has decided to live the club and start another life. Real Madrid is going to become a nightmare club for European tournament especially that Laliga where they think El clasico is something they can use to bully Real Madrid, Xavi will be somewhere happy that he left Barcelona before this move otherwise it would be a big challenge for him to win Laliga in the future.
