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.
But he is the very same person who did so well under the same coach in his early years at Atlético Madrid until the thought of getting more money fucked up everything, and he ended up in Barcelona. He has never been the same again.If he goes to Saudi Arabia, it will also be sad.
I guess he will be very happy since more money is there since his current football form is now a shadow of its past 
But at the World Cup, Griezmann was consistently the best/one of the best in the French team (not the weakest team in the tournament
). I don't think the money ruined him, rather the wrong team for him. It seems to me that Atlético will continue to degrade and it is unlikely that he will be able to resist this trend. And by the way, judging by the scandal over the captaincy in the French national team, Griezmann is interested not only in money - he still has sports ambitions. If he was only interested in money, he would have endured the appointment of Mbappe and not got involved in a scandal from which it was impossible to emerge victorious.
