Mauricio Pochettino's tenure as USMNT head coach has been marked by both ambitious pronouncements and considerable scrutiny, particularly concerning team chemistry. As the USMNT prepares for the 2026 World Cup on home soil, Pochettino's vision for the team's development is under intense examination.

Pochettino has repeatedly emphasized the importance of creating a winning culture within the USMNT. He envisions a team where players are fully focused and committed, prioritizing the national team above personal interests. This commitment, he believes, is essential for fostering a cohesive and successful squad capable of competing at the highest level. In May 2025, Pochettino stressed that players arriving at camp should be focused solely on the national team, aiming to "create this culture about winning."

However, Pochettino's approach has faced criticism, especially regarding his roster decisions and handling of key players. The pre-Gold Cup roster in May 2025, notably missing stars like Christian Pulisic and Antonee Robinson, sparked debate about the team's ability to build chemistry and momentum. Some observers argued that these absences hindered the team's progress and signaled a missed opportunity to solidify the squad ahead of the World Cup.

The situation surrounding Christian Pulisic's availability for the Gold Cup further complicated matters. Pulisic expressed his desire to participate in pre-tournament friendlies but requested to skip the Gold Cup due to fatigue. Pochettino, however, insisted on using the same squad for both the friendlies and the tournament, leading to Pulisic's exclusion. This decision drew criticism from former USMNT players, with some suggesting that Pochettino needed to assert his authority and ensure that no player was bigger than the team.

Pochettino defended his decision, stating that players need to adhere to the team's plan and that he, as head coach, is responsible for making those decisions. He emphasized the importance of having a consistent group of players to prepare for the Gold Cup, highlighting its significance as a competition. Despite the controversy, Pochettino maintained that communication with Pulisic was good and that he treats all players with equal respect.

Despite the challenges, Pochettino remains optimistic about the USMNT's potential. In March 2025, he expressed his belief that the team could become the best in the world within five to ten years. He also praised U.S. Soccer's investment in a new national training center, viewing it as a crucial step in establishing soccer as a serious sport in the United States.

As the USMNT moves forward, Pochettino's ability to foster team chemistry and create a winning culture will be critical. With the 2026 World Cup looming, the pressure is on Pochettino to integrate his players, implement his tactical vision, and guide the team to success. While challenges and controversies may arise, Pochettino's commitment to building a focused and competitive squad remains central to his approach.
