Mauricio Pochettino appears to recognize the enormity of the problems facing his U.S. men’s national team after it crashed out of the CONCACAF Nations League this week with two dismal losses in a tournament it had won every other time it had been contested. Pochettino also believes he has enough time to solve those problems in the next year before the Americans’ home World Cup. The Argentine coach tried his best to radiate optimism and problem-solving acumen after the U.S. fell 2-1 to Canada in the tournament’s third-place match. The U.S. hadn’t lost a competitive match to its northern neighbors since 1957.
