U.S. soccer chief non-committal on future of Klinsmann (Reuters)

(Reuters) - Jurgen Klinsmann did not even attempt to sugarcoat his reaction to the performance of his United States team after their 4-0 humiliation in a World Cup qualifier against Costa Rica on Tuesday. The normally upbeat Klinsmann admitted the performance of his side, which mustered only one shot on goal in the Costa Rica capital of San Jose, had been unacceptable. "It is a bitter pill to swallow." Speculation over Klinsmann's tenure as head coach was already rampant before the game, even as U.S. Soccer president Sunil Gulati remained publicly supportive.
