The forward appeared in a short video released by Movistar, in which he says: "You'll be fed up with the comments saying if I'm going, if I'm staying, how much they give me, how much they don't give me".
Having long gone past the point that anybody really cares, Antoine Griezmann has plunged the ongoing masquerade about his future at club level into sheer farce.
The French attacker has been tempting and teasing this news for months but kept his promise when he said the news would come before the World Cup.
The show was reminiscent of highly scrutinized LeBron James's 2010 decision.
The Frenchman has been linked with a move away from the Spanish capital for well over 12 months, with a move to Manchester United highly anticipated last summer. As a effect of his comments, Atletico reported Barca to Federation Internationale de Football Association for making an illegal approach for their player.
Griezmann, Atletico's top scorer for the past three seasons, said at a news conference on Tuesday that the decision was made but he was not yet ready to go public. France Football reported Griezmann will sign a new contract in Russian Federation at some point on Thursday.
Eventually, Atletico snapped. A furious statement released by the club said "enough is enough" and condemned Barca's "inappropriate conduct" in their attempts to sign Griezmann.
Griezmann announced on Spanish television on Thursday that he would be staying at Atletico next season amid heavy interest from La Liga champions Barcelona.
The La Liga giants agreed a fee with Monaco to sign Griezmann's global team-mate Thomas Lemar.
