Remi is not a professional soccer player, nor has he ever been. I read about him in some French magazine awhile back, after he managed to get on the field after a French cup soccer game and pretended to be a winning player. Turns out he lost his job, was bored all the time...so he and a friend started making videos.
He's from montpellier, and thats his local team. Thats why you see him in their jersey, and in some cases inside their locker room/stadium. But he's never played professionally.
