Antoine Griezmann's former advisor believes Barcelona have let him down.

Eric Olhats, who was an advisor to Griezmann from his time as a junior with Real Sociedad right up to last season, believes the former Atletico Madrid man has been treated poorly.

He explained, "I'm a little bit sad at the situation.

"I don't know what (coach Ernesto) Valverde has planned, what I do know is that he always had a strong desire to go to Barcelona. I am a bit sad for the situation and I knew it was going to be difficult. I have the impression that he was sold a project where he was going to fit into a position that suited his qualities, in relation to Messi, and it's not going as planned."

Regarding his relationship with Lionel Messi, which is reportedly not ideal yet, Olhats said: "Knowing how Antoine is, it's not his style to be on bad terms with him. He would try to be the best mediator possible. I'm not too worried about his relationship with Messi because he's a good guy."
