Atletico Madrid has reported Barcelona to FIFA for approaching Antoine Griezmann ilegally. "If I offended some people I'm sorry", he wrote.
As the January transfer window rolls into view, Griezmann's links to Man United and Barcelona are again getting louder.
"I recognise that's it's insensitive on my part".
"There's a good understanding, maybe there have been talks".
It had been expected the switch would eventually happen in 2018 until Barcelona entered the mix.
Atletico Madrid's complaint could be forwarded to a FIFA committee that oversees transfers and their legality, but it unlikely to lead to discipline.
Diego Simeone last week revealed that he would not stand in Griezmann's way if the 26-year-old revealed a desire to try his luck elsewhere. "Though, I don't know anything for sure". Rumours are inevitable in the football world.
This is where the complaint from Atletico stems from.
FIFA's rules clearly stipulates that clubs that wish to sign a player, must first inform the player's club before they can then begin to negotiate with the player.
Gremio recently threatened Barcelona with legal action after a photograph of Brazilian starlet Arthur Melo wearing a Blaugrana shirt alongside club technical secretary Robert Fernandez was leaked through social media.
Barca remain firm favourites to land Philippe Coutinho from Liverpool, but could turn their attentions to Alexis Sanchez or Mesut Ozil who are both available on a free transfer next summer.
Marca says that Atletico believes that Barcelona's tactics are against the integrity of La Liga as it destabilize Simeone's side.
