Mauricio Pochettino named 27 players for the March international window — the last opportunity to assess form and fitness before submitting his final World Cup roster in late May. Christian Pulisic, with 82 caps, leads a squad that includes nine MLS players, reflecting both the domestic league's depth and Pochettino's willingness to consider players outside European club football for the tournament. Sergiño Dest and Tyler Adams miss through injury; Adams's absence at defensive midfield is the sharpest selection gap, given the role he played in the US run to the quarter-finals at Qatar 2022.
The two fixtures carry different weights. Belgium, on 28 March in Atlanta, are Group G opponents alongside Iran — the group whose composition remains unresolved following FIFA's rejection of Iran's relocation request and the unresolved question of Iran's participation ahead of the 30 April FIFA Congress deadline . Portugal, on 31 March, are among the tournament's strongest qualifying sides and a plausible knockout-round opponent for one of the co-hosts. Pochettino has roughly seven weeks between the Atlanta window and final roster submission; players who distinguish themselves against Belgium and Portugal move to the front of selection decisions for positions that remain open.
