Arjen Robben, The Netherlands
Petulant is the word that comes to mind. Robben is a terror for defenders on the flank, cutting in from the right and ripping a shot with his left. But man, does he complain non-stop about fouls, perceived fouls, teammates who give him the ball in the wrong spot, teammates who don't give him the ball, pretty much everything. In the words of Officer Farva, he's the type of player who probably deserves to have his face punch-a-sized.
