Atletico Madrid have asked La Liga to block Antoine Griezmann’s registration at Barcelona, according to a report from Sky Sports.
The Blaugrana completed the signing of the French forward when they triggered his €120m release clause this month, but Kaveh Solhekol has reported Los Rojiblancos feel they are entitled to €200m.
Atleti now allege that the signing had been done before the clause dropped to €120m from €200m, and that they are now thus entitled to a further €80m from Barca.
A statement from Atleti earlier this month alleged that they would take the Catalan giants to court over the deal, which they believe they can prove was agreed before the clause dropped.
“Atlético de Madrid believes that the amount deposited is insufficient to meet its rescission clause, since it is obvious that the commitment of the player and that of Football Club Barcelona was closed before the aforementioned clause was reduced from €200m to €120m,” read the statement.
“It was also prior to the date on which the clause was modified the communication that the player made on May 14 announcing his disengagement from the club.
“Atlético de Madrid believes that the termination of the contract occurred before the end of last season due to events, acts and demonstrations carried out by the player and that is why he has already started the procedures he considered appropriate for the defense of his rights and interests legitimate.”
