Griezmann concedes he has MLS ambitions.
He told Sport: "My current goal? Winning the Liga and the Champions League with Barça is a dream, and also my goal.
"After winning, whatever happens, there is another World Cup to be won in Qatar. And after MLS.
"I don't know which team, but I really want to play there. For me, it's a goal to end my career in the United States, with the possibility of playing well and being part of the team fighting for a title."
