Antoine Griezmann says he's made a decision on his future but declined to reveal it.
"I apologize -- I am really very sorry," said Griezmann. "I know that many of you were waiting for [his decision], but I will not be revealing it today. I have made my choice.
"However, today is not the time, nor the place, to say what it is."
Griezmann has been linked with transfers to Barcelona and Manchester United.
Barcelona had hoped to sign the 27-year-old on July 1, when his release clause drops to €100 million, but Atletico have offered him an improved contract worth a reported €23 million a year.
