Barcelona president Josep Maria Bartomeu insists Lionel Messi is happy at the Nou Camp.

Messi impressed in victory over Atletico Madrid.

"You can see Messi's happiness out on the pitch. You can see it in the level of his performance at the moment, in his smile; we are calm because Leo is good," Bartomeu told BeIN Sports.

He also denied any "bad relationship at all" in the 'Blaugrana' dressing room.

"There are always things going on in a team, but the relationship is good and there's a good atmosphere. I see them first hand and there is great unity," he added.
