I find the tag choker kind of funny. Looking to barca last match you could call messi choker, yet the match before he came on injuried and decided a game. Players can't have every match their best games, but that doesn't make them chokers.
Even players like Molinaro aren't chokers, not to mention someone like Ibra or RVP, they are playing in top level teams and top level leagues each day they are far from chokers as it could be.
