The Royal Spanish Football Federation has commenced investigations on the transfer which involved Antoine Griezmann moving to Barcelona from Atletico Madrid.

Atletico Madrid lodged official complaints against Barcelona over how the Laliga Santander defending champions signed their star attacker, Antoine Griezmann.
The Rojiblancos released an official statements minutes after Barcelona announced the €120 million capture of Antoine for 5 years.
In the statement, Atleti argued that Griezmann had signed a contract with Barcelona as far back as in March unbeknownst to everyone else. And as such, are supposed to pay €200 million as release clause instead of the €120 million they dropped at the Spanish FA’s office to cancel out the French player’s contract with them.
On May 14, Antoine Griezmann informed Miguel Ángel Gil, Diego Pablo Simeone and Andrea Berta of his decision to leave our club at the end of the season. In the days that followed that meeting, Atlético de Madrid learned that FC Barcelona and the player had reached an agreement in March, specifically in the days following the return match of our Champions League tie against Juventus, and that they had been negotiating the terms of the agreement since mid-February.
The club said in a statement on their website dated 5th of July.
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 the Football Club Barcelona was closed before the aforementioned clause was reduced from 200 to 120 million euros. euros 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 initiated the procedures he considered appropriate for the defense of his rights and interests.
– As quoted from Red and white club’s website in another statement on the day Griezmann was announced by Barcelona (12th of July).
Spanish media outlets confirmed that RFEF has begun investigations in a bid to get to the root of the tussle between the two clubs.
Antoine Griezmann’s plague at the Wanda Metropolitan stadium was also destroyed by angry fans who showed their discontent over how the player left the club.
It remains to be seen if Barcelona will be forced to cough out €200 million or Atleti will be made to accept the €120 million payed by Barça.
