The 26-year-old had been linked with a move to Manchester United, before their interest in him disappeared.
Atlético, along with arch rivals Real Madrid, were handed two-window transfer bans in January 2016 for multiple breaches of global football's rules on the registration of under-18s, with both clubs failing in their appeals to Fifa last September. "I've chose to stay", Griezmann told Telefoot. Atlético can not recruit. With my sporting advisor, Eric Olhats, we made a decision to stay.
But now Lacazette has been told to reject Mourinho's advances and remain at Lyon until Atletico's ban is over, with the Spanish side having previously reached an agreement with the Frenchman until they were prevented from signing any more players.
Atletico immediately described the CAS ruling as unfair and said it would cause "irreparable damage" to the club.
After giving himself a 6/10 chance of joining United barely two weeks ago, Griezmann has now completed a full U-turn and decisively committed his future to Atletico.
"It is a hard moment for the club and for my teammates".
And after hinting on Twitter this week he could stay at Atletico, Griezmann has now confirmed the club's transfer ban means he will definitely not leave the Vicente Calderon this summer.
