Christian Pulisic starts for the USA at the Al Thumama Stadium in Qatar for the decisive World Cup group clash with Iran in Group B.
USA know that only a win will take them through to the knockout stages to face either the Netherlands or Senegal in the last 16, depending on whether they finish top or second in the group.
Pulisic has started all of his nation's games at the tournament so far, impressing against England in Friday's 0-0 draw after setting up their only goal of the finals against Wales in the opener for Timothy Weah. The 23-year-old will be relied upon to provide a moment of inspiration on a tense night as an inspired Iran hope to seal a shock win.

Pulisic's future at Chelsea is still the centre of much speculation following a challenging start to the season. A bit like Hakim Ziyech, the winger has struggled to gain consistent minutes under either Thomas Tuchel or Graham Potter.
Gregg Berhalter has given Pulisic the trust to start on the left side of his 4-3-3 formation, a role he did impress in under Frank Lampard back in 2020. The USA's lineup is also the youngest fielded by any nation in Qatar so far.
Pulisic's Chelsea teammates from England - Mason Mount, Raheem Sterling and Conor Gallagher - will also be aiming to secure qualification on Tuesday night as they face Wales.
Earlier on Tuesday, Kalidou Koulibaly scored a crucial winner for Senegal in a huge 2-1 win over Ecuador to clinch qualification from Group A, with Edouard Mendy involved too.
