Atletico Madrid have asked La Liga to block the sale of Antoine Griezmann to Barcelona due to a dispute over the transfer fee.

Barcelona announced the signing of Griezmann this month for €120 million ($133.75 million) but Atletico complained that not enough was paid.

The buy-out clause had dropped from €200 million to €120 million on July 1, but Atletico claim that Griezmann's May 14 announcement that he was leaving the club is proof a deal was struck between the player and Barcelona much earlier.
