Real Madrid shouldn't allow the Mbappe scenario to negatively impact them and cause them to lose one of their finest players because, in my opinion, even if they sell Valverde, PSG won't let Mbappe join any other team this season. Valverde is one of Real Madrid's top players, and in my opinion, he will go to midfielder for the upcoming season. He was previously utilised by Real Madrid as a winger player, but he is much more effective there.
Real Madrid would therefore be well to exercise caution before making decisions that they may come to regret. The league is about to begin, and if they make a mistake, their performance will be subpar the following year.
No Real Madrid won't let any scenario regarding Mbappe take control of their general approach to transfers this season, but he is an important player on their list. I would say he is not just one piece of the puzzle, but several pieces given how good he is and how much influence he can have on a team and on the game. But now Real Madrid will be waiting for Mbappe's response to the deadline Khelaifi gave in an interview. He said that Mbappe either decides to sign a new contract within the next two weeks or he will be sold.
I agree with what you said, Valverde is a very useful player for Madrid and there is no way Madrid will give up one of their best assets to bring Mbappe because they also want a very high price for Mbappe.
Now maybe we'll just wait to see how things go with Mbappe and PSG first because this also determines if in the end Mbappe still remains with his wishes then this will allow him to be released just like that with the 250 million + that was always discussed before. Everything depends on Mbappe because if he stays with his previous statement then his drama about Madrid will continue to lengthen but if he decides to extend the contract then this will be finished but on the other hand it is a loss for Mbappe because he will still be the same as before without any improvement at PSG.
