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.
Depends on the situation really, where you are looking at the player changes. If you look at it as a fan you may say "he is a good striker he should stay" but if you look at it from owners perspective that's a lot of money to reject to and as a team owner you have to think about the teams future as well.
I believe that they are going to do just that and I think they are going to end up with a lot of money to replace him and also get some other players as well. This is why I believe that we should be considering this as a good deal. I hope that we could end up with something that is better for next season if they do this deal, or maybe not but they have to keep trying this in order to grow the team and try to be better.
