Here's an amazing fact for you. The Guatemala national team have been together and training fully ever since Monday and the United States haven't even announced who they're calling up for their two World Cup qualifiers starting next week yet.
Walter Claveri, the Guatemala head coach, has had 18 of his 23 players in training in Guatemala City, the site of the first qualifier next Friday, ever since Monday. They'll basically have a week's head start on the USA who won't be together until presumably this coming Monday at the earliest. Factor in travel and rest/recuperation from weekend matches and the USMNT will maybe have three good days to prepare.
