Now Antoine Griezmann is a player of Barcelona and he is there to fight to be the important player. It has been 12 matches in La Liga and 3 matches in Champions League this season he has taken a part. I think he is managing his self-confident with his team-mate to be a successful player.
Griezmann is not failed to show his best because he is a new player in Camp Nou. He still has time to adapt with the philosophy of Barcelona. He must understand that it is not easy but I think he can do it. Barca brought him to Camp Nou from Atletico Madrid in a € 120million. He is a wonderful player and Barca will take many advantages during this season.
He is a national team member of French and he is still 28-year-old right now. He will be one of the most valuable player for Barca. It is normal for new player to adapt the situation in a new team. However Griezmann will keep leaning to know much more about the Barca's style. It is not easy to fit with Messi and friends but I am sure that he will be a precious asset for Barcelona.
