Griezmann is a brilliant player, but his decision to leave Atletico in my opinion is a bad one. Because with Barcelona Griezmann couldn't find
his best performance. Especially if Messi extends the contract and Barcelona manages to bring in Depay, it looks like Griezmann's position
will be threatened. My suggestion is that Griezmann chooses another club to play for, according to rumors if Ronaldo leaves Juventus,
Griezmann is one of Juventus targets to replace Ronaldo. I hope Griezmann can move to Juventus or another club, so that his career
can develop even better.
Griezman can be a legend in Atletico Madrid if he want to contribute more and end his career there. After some successes in Atletico Madrid as well as some defeats in final matches, and after the World Cup 2018 title, Griezman want to move to a higher level.
I guess he want to win Champions League and personal titles. Maybe he felt Barcelona with Messi can help him move higher and feel tired with not too big chance to win Champions League with Atletico. In football, we never know anything, some legendary players never win Champions League. Examples Ronaldo (Brazil), Totti, Baggio, Ballack and some never win World Cup or Euro. But when a player gets a big title, they will want to get another. It is what Griezman thought maybe.
I understand the reason Griezmann left Atletico, he thinks Barcelona and Messi can give him a lot of titles. It turns out that the reality is
not as expected, Griezmann is having a difficult time at Barcelona, his performance is getting worse. Therefore, if Griezmann is still at Atletico,
it is very possible to become a legend and be able to win trophies with Atletico. Sometimes moving to a big club is not the best option for some players.
