Former Real Sociedad coach Martin Lasarte is confident Antoine Griezmann will succeed with Barcelona.

Griezmann finally completed his long-awaited move from Atlético de Madrid to Camp Nou on Friday having seemed set to join Barça last year before opting to stay put. Barça triggered the €120million release clause in his contract, although Atlético are demanding a further €80m as one of modern football's longest transfer sagas rumbles on.

Lasarte told Omnisport of his former La Real starlet: "His signing for Barcelona - it would have happened last year, so it's something everybody knew.

"Barcelona supporters were angry but I think staying at Atlético was the right decision for him. Now I think it's the right time [to move] because after Barcelona failed to win all the trophies last season - and in a bad way - so I think Griezmann could fit easily and help them to come back, because he is a happy guy and a very positive one.

"I think Griezmann will fit like a ring on a finger after Barcelona's situation last season."
