Griezmann has been newly signed by Atletico Madrid on a permanent deal. But interestingly there are still rumours like he can join one of Saudi Arabia teams this summer. Considering that he has signed a three-year contract with Atletico Madrid he shouldn't be leaving now already. I think he would stay for one more season at least and then maybe he would decide to earn much more money by joining a Saudi Arabia team. Atletico Madrid really need him now considering his last season effort.
While there is a chance of at least one of Felix and Morata to leave this summer Atletico Madrid should keep Griezmann to keep their scoring skills high.
Griezmann is still a fresh signing for Atletico Madrid and the only way he can leave if one of the saudi teams offers a lot of money. They already wasted a lot so this can still happen. Griezmann isnt that young anymore so this option still isnt off the table. Transfer window in saudi arabia is longer then europe for 3 weeks so still things can happen.
