Griezmann was delivering sensational kind of football in his first spell at Atletico Madrid but has failed to deliver kind of football in his second spell.
I don't know which Griezmann you watched but the Antoine Griezmann of Atletico was exceptional last season.
Griezmann was even in the La Liga team of the season and was a candidate for the player of the season.
If he feels Saudi is the best decision for him then fine. Atletico need money and they might be happy to sell, but I doubt they would want to lose Griezmann.
Griezmann still wants to stay at Atletico and Atletico still want to keep Griezmann but they might sell him to balance the books if a good offer arrives.
Most of the time peoples have no idea what are they talking and who they are talking about, but things are going as usual with Antonia Griezmann is surely one of the best striker from France, and he is doing good in Atlético Madrid while he has some ups and downs as well, but his career is still good, and he can do better in next few years even now he is in limelight for possible transfer but most chances he will not go with this and keep his place here in Atlético Madrid which is good side and can do better in this season as well.
Diego Simone needs to change his tactics and strategy which is not allowing them for having aggressive approach and better results because recently his defensive approach is not working, hopefully things will be change and both Antonio Griezmann and Atlético Madrid will be at their best for this season again.
