Well Casemiro is still a vibrant player, I won't be surprised if a club comes for him on loan or outrightly buy him despite his huge weekly wages, this Saudi guys aren't playing with you when they are coming for a player, so in the aspect of the salary I don't think any Club that really wants him would look at that, Manchester United just want to get rid of him, probably because he doesn't fall into the specification of what Amorim needs for his team, just the way he did for Rashford.
Definitely Casemiro’s time to leave Manchester United is very close be it loan or permanent transfer. He has had some bad performances in his last games and most of the fans doesn’t trust him anymore so i don’t think he is missed at all with this injury so definitely they will look for a way to dispose him soon.
I believe The Saudi Arabia teams will be patiently waiting for him to be fit so they can come for him finally, his time is almost over so it will be best if he joins other players in the Saudi league.
Casemiro will be perfect fit for some Saudi pro League teams, he should just consider moving to any team that come for him in order to keep his football career on, or he should just retire just like other players because he can’t fit in in any big team across Europe anymore.
I don’t know why he is still not playing there yet because that is the place that suits him better now instead playing in a struggling Manchester United team that doesn’t believe him. I doubt if he can retire now, he will definitely accept any club that comes for him regardless of the league they play because I don’t think he can play actively in top leagues and give them good performances.
