Wait a minute, is Real Madrid also experiencing financial difficulties at the moment? I guess this is bad news about them, but I'm not sure about that. The way Real Madrid are signing players does not reflect that they are in a bad financial situation, but perhaps Real Madrid are starting to save money for Ancelotti's last season with them.
Real Madrid has spent at least €129.50m building up its squad. They have signed at least 5 players including Jude Bellingham, Arda Güler, Kepa Arrizabalaga, Fran Garcia and Joselu. Two of the 5 players are players on loan, while the other 3 are signed on a permanent basis.
I think we have no proof to claim Real Madrid is experiencing a financial problem. They could sign some new players, even they signed Jude Bellingham with an expensive price. They also ever made an offer for Mbappe with a fantastic amount of money. Unfortunately, it was not enough to have a deal with PSG.

If Real Madrid is not very aggressive to sign new players, they must have a reason. Real Madrid isn't a typical club which carelessly spend money to unnecessary players.
