Adios, Spain! The defending World Cup champion lost to Chile in a surprising upset on Wednesday.

Spain, which still has one group game left to play, lost to Chile 2-0. Eduardo Vargas scored Chile's first goal in the 20th minute of the game, and Charles Aránguiz scored the second goal just before halftime, thanks in part to an error by Spain's Iker Casillas.
