There will be changes, that's for sure. How many? Too soon to tell. But we do know that the U.S. men's national team that takes on El Salvador will look at least slightly different to the one that took on Grenada.
Not that they'll want to change too much, mind you, given the result of that Grenada game. A 7-1 shellacking of an overmatched team, although one that saw several USMNT stars step up with big performances.
El Salvador will be a different type of game, a much better team. They drew the U.S. 1-1 the last time these two teams met in June, with the U.S. needing a last-gasp equalizer from Jordan Morris to escape the Estadio Cuscatlan with a point. Hugo Perez, the former USMNT star and youth coach, has El Salvador playing ball. They'll be ready to play.
The U.S., though, know what they'll need: just a point. A draw will be enough to take them to the next round of the Nations League, where they'll look to defend their title. But who will get them there? What players can Anthony Hudson turn to to keep the good vibes going?
Does he start Christian Pulisic, who masterminded the 7-1 win? Does Gio Reyna get another run in midfield or does the U.S. revert to a more familiar shape? Will someone like Alejandro Zendejas or Taylor Booth make the leap into the XI after shining off the bench last time out?
Here's a look at who should start for the U.S. in Orlando on Monday night:
