What happened: U.S. Soccer confirmed Perez's attendance for Sunday's La Liga fixture. Johnny Cardoso represents Atletico Madrid, while Alex Freeman is with Villarreal.

Why it matters: The visit gives national-team staff an in-person evaluation opportunity for two U.S. internationals. Any on-field assessment depends on whether either player enters the match.

What to watch: Watch for substitute appearances and any follow-up from U.S. Soccer.
