It's a celebration in FIFA (game), he's just copying it because that's what he always chooses in-game (muscle memory with a controller in hand). He'll change it now it's an issue, unless it's unique to the 'real player' world, in which case he will probably trademark itDoes anyone know what that hand gesture where he partially covers his face with crossed fingers means?
Perhaps someone more familiar with 2010s pop culture thx
[Update]: Who am I kidding, EA have definitely already trademarked it. Probably auctioned it off to Stevie B.
