The USMNT is set to play against Belgium, ranked ninth in the world, in a friendly match with an experimental back line. Center back Chris Richards, perhaps the most important defender going into the World Cup, will miss the friendly due to a knee issue. Fellow center back Miles Robinson was also ruled out of the international break, which also includes a friendly against Portugal. Head coach Mauricio Pochettino is facing a significant selection dilemma ahead of the tournament. Despite these injuries, they do not impact their World Cup chances. The team has been on a five-game unbeaten run since adopting a new system with three center backs, allowing Pochetino to have as many defenders available as possible.
