The forward bid his farewells to the Atleti fans in a heartfelt video posted on social media, saying:
“After talking with Cholo, Miguel Angel and the people from the offices, I wanted to talk to the fans who have given me a lot of love,” Griezmann said.
“I have decided to leave, see other things, have other challenges and with great difficulty, this is what I feel and I need.
“It’s been five great years where I’ve won my first important trophies with a club. It’s been a very important stage.
“I have enjoyed a lot, I have left everything in the field, I have tried to behave well, I have tried to give joy to the people who have come to the Metropolitano and also away from home, and I only have gratitude for all of you”.
