I'm sure about Real Madrid's finances because the financial stability of Real Madrid's management is still safe, maybe related to Mbappe, that's how the PSG management is and if it is agreed that it can happen Mbappe can become a Real Madrid squad this season, but every step what Real wants Madrid will definitely come true if it comes to finances I don't doubt it,
Real Madrid is still ambitious with its thirst for titles, so every row of star players will be the target.
I also feel that Mbappe will join Real Madrid. There must be a reason why Mbappe refused to renew the contract offered by PSG (even though the salary offered was bigger than before). Real Madrid is one of the biggest teams in the world, and many players want to be able to play for Real Madrid (maybe Mbappe is one of them).
If Mbappe really joins Real Madrid, then Real Madrid's chances in the title race will be even greater (they just need to find a strong defender to replace Ramos).
