Here's a shirtless fan (with a carved "Y" of chest hair) verbally abusing Robin Van Persie as he leaves the Dutch hotel, yelling "cheater" and making diving pantomimes. Why? He thinks it's Arjen Robben. All Dutch people must look alike.
(The Youtube description, and much of the media coverage, claims that this guy's a Mexican fan, a natural assumption, while the broadcaster for Dutch state TV pretty clearly says at 0:09 that he's American. He can be both.)
