Antoine Griezmann admitted that he was suffering from a lack of confidence in his decision making at Barcelona.

"I'm in the process of learning and understanding how my team-mates play as everything is new to me. I'm still trying to read the runs and off the ball movement ... At present when I get the ball I have a certain lack of confidence in when to pass or when to shoot on goal, this I'm sure is something that will change with the passing of time," said Griezmann.

Griezmann also added that his relationship with Luis Suarez and Lionel Messi is taking time to build.

"I'm pretty shy and sometimes have problems talking to others. It's rare that I strike up a conversation. Luis, Leo and myself have had meals together and the relationship can only improve over time."
