We can't be sure about his fitness yet but I can say Casemiro is still at a level in which he can play for more years in top-level teams like Manchester United without problems, however, I think Manchester United should keep Casemiro but even if they don't want to have this palyer any more I think Casemiro can choose to stay in another team in the Euroa which there are obviously many offers for this palyer.
But moving to the Saudi countries is just too soon for a player like Casemiro who can play at this level for his team.
Casemiro is still 31 years old and in Europe his contribution can still be utilized. If Manchester United decides to sell him it might be the wrong choice. Instead of selling Casemiro, of course there are other players who are worth selling and indeed their contribution is no longer of benefit to the club. Casemiro could have received another offer from his original club Real Madrid but it would be better to be part of Manchester United because from the start Casemiro goal was to try to improve this club.
I think it was just made up by the media by saying 400 million I don't think this will happen for the sale of Osimhen because this player is not his level at that price, it also doesn't make sense and who wants to buy him? If you say this is nonsense then I believe it.
Mbappe does have a high value at the moment the contract at 200M is still very possible especially now that Real Madrid is still eyeing him until his contract expires. Let's see how Real Madrid make a special offer to Mbappe.
I don't know if the 150M for Osimhen will go to Chelsea this is just a rumor while Real Madrid will not prioritize the Napoli player, while for the Arab club Osimhen there is no interest there.
Between Osimhen and Mbappe, Mbappe is clearly more useful because the price for OSimhen set by Napoli is just an alibi not to lose their key player. As we know without Osimhen contribution Napoli might not have developed like this. Then, if Osimhen stays at Napoli, his chances of becoming a football star in this era will become even slimmer and he will even be easily replaced by another player. Europe has Haaland and Mbappe currently in the spotlight. So Osimhen is just a player who was forced by Napoli to be part of the competition for star players.
