Barcelona plan to file a lawsuit demanding Atletico Madrid pay them €40 million for Antoine Griezmann, sources have told ESPN.

Griezmann, 31, rejoined Atletico on a two-year loan in 2021 and the two clubs are in dispute over a clause which would see the deal made permanent.

Sources close to the Catalan club have told ESPN that Barca believe the fact Griezmann played over 45 minutes in 30 of the 37 games he was available for last season means Atletico are now obliged to sign him for €40m.

Atletico, meanwhile, claim Griezmann must play over 45 minutes in 50% of the games he is selectable for over two seasons, not just one, for the clause to take effect.
