It hasn't been the smoothest transition into the public sphere for Jonathan Klinsmann, but he has no one else to blame but himself.

The 18-year-old son of U.S. men's soccer coach Jurgen Klinsmann received a red card in an international match against Germany this week, exiting the game in stoppage time as the Americans held on for a 2-1 win. Jonathan, the goalkeeper, was booted from the game after receiving his second yellow card on a foul play that awarded the Germans a penalty kick.

Kids make mistakes, sure. But it's fair to suggest Jonathan Klinsmann might not be the most delightful person you've never met. Long before he got kicked out of a largely inconsequential soccer game, young Jonathan faced the heat for openly mocking Landon Donovan after the star's omission from the World Cup roster this summer:

That's not a good look -- particularly for a young guy looking to climb the American soccer ladder Landon Donovan more or less built, and especially not from the kid of the guy that snubbed Donovan in less-than-glorious fashion.

Jonathan Klinsmann allegedly sent an email to Landon Donovan to apologize. But according to Alexi Lalas, it's not clear if Donovan ever made contact with the little jerk.

Someone should tell young Jonathan to respect his elders, and also inform him that the goalie is without question the worst person to have receive a red card in a match.

Preferably, that message will come from his father.
