Casemiro is said to be a target by PSG and Al-Hilal now. You know he has been quite far away from his old performances recently. This is why Manchester United are said to be thinking of parting ways with him. His time with injury didn't end up well for him. He is still a quality player but he needs to improve his effort much more than this.
Casemiro would likely leave Manchester United, but i don't think it can be to PSG. I found it weird when United paid £70m for a player of his age, there is no doubting his quality, but when a player is already above 30, he should not cost as much as that, except it is a Saudi club that is doing the signing, lol.
PSG are looking for younger players, especially from France, that is the direction the club has decided to take, they no longer want to sign only big stars, but they want to nurture young talents, if Casemiro leaves United, Saudi Arabia would be a more likely destination that the French champions.
PSG has indeed turned towards younger talents from France. I like the approach and their whole attacking line if French now, which I thought is an amazing idea and is quite promising, but let's see how far Mbappe + Kolo Muani + Dembele can take PSG this season. But did PSG abandon the purchase strategy of old stars entirely? Maybe you are right, but Ramos was also one of those transfers I never understood. Perhaps Casemiro is a player they would want for the defense, but I agree that it is more likely that Casemiro himself wants once of these juicy contracts in Saudi Arabia.
