I'm not a fickle sports fan, but since my number two choice France flamed out immediately and the USA unfortunately succumbed to the gallant fight, I now throw my support behind (drumroll):

Besides the fact that their uniforms are objectively awesome, I also have some Dutch friends who would appreciate my moral support.
U-S-A! U-S-A! Allez les bleus! Oranje!
