Saint-Étienne forward Nolan Roux was clearly frustrated during his side's match against Tîrgu MureÅŸ in the Europa League earlier this week, but not many expected him to take out his frustrations on a poor innocent ball boy who was standing on the side of the pitch.

Well, that's unfair, he clearly didn't mean it, but as he went to boot the ball into the stands and let off some steam, he accidentally caught the poor lad square in the face.
