“The complaint has been presented for repeated contact between Barcelona, the player and his team,” an Atletico source told AFP.
Griezmann renewed his contract until 2022 in June and Atletico consider contact made by Barcelona not only breaks FIFA’s rules, but could also affect the integrity of La Liga.
Barcelona lead the league with Atletico their closest challengers six points behind in second.
“He is a player under a long contract and this can’t happen. Moreover, the club considers that it could affect the competition where Barca are currently top and Atletico second,” added the Atletico source.
Barca were slapped with a one-year transfer ban for the illegal recruitment of foreign minors by FIFA that was served in 2015.
Should the Catalan giants be found guilty, they could be handed another ban on registering new players.
“We can confirm that we have received a complaint from Atletico de Madrid concerning the said matter,” a FIFA spokesperson told AFP.
Barcelona-based sports daily Mundo Deportivo reported on Sunday that Barca’s president Josep Maria Bartomeu had recently met with Griezmann’s family.
The Catalan giants are expected to be willing to pay the French international’s €100m buyout clause at the end of the season to avoid negotiating with Atletico.
