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.
Griezmann is not a "fresh" signing for Atlético, it's just that he was initially on loan with an option to renew and buy. It is a pity that he did not find a better option than Atlético, where he has a conflict with Simeone and where, due to the style of play, he cannot fully reveal his talent. If he goes to Saudi Arabia, it will also be sad.
