Mauricio Pochettino wasn’t hired to help the U.S. men’s national team win games against regional opponents or friendlies. Those were two areas in which predecessor Gregg Berhalter was still excelling up until the end of his tenure as coach. The perceived value of investing $6 million annually in the Argentine manager was his history of success in the club game. With his pedigree, the theory went, his fresh eyes could find diamonds in the rough of his new player pool and configure a system that would give the USMNT a better chance of making a deep run at the 2026 World Cup.
A year isn’t a long time in a job, but it’s over halfway from when Pochettino assumed the role and when his ultimate performance review will commence after the World Cup comes to North America. At a certain point along the way, it’s expected there would be signs of progress.
On Tuesday night, we finally saw some evidence of evolution. Pochettino seemed to adapt based on persistent issues with his base 4-2-3-1 — which he had used in all 11 games to date in 2025 — to a 3-4-2-1. By dropping a player from the attacking line beneath his striker and introducing a third center back, his team was able to play with more decisiveness in transition and more downhill intentionality.
“I think we have players that play in this new formation,” Pochettino said after his team’s 2-0 win over Japan on Tuesday, listing a few defenders whose clubs play a similar system. “I think it’s good to have different plans, approach to the games, use different formations.”
It was successful, albeit in a win over a fully rotated side that qualified for the World Cup this spring. But it also led to a more entertaining performance from the USMNT than we’ve seen in some time. That latter point seems more dependably replicable in this shape, too.
Throughout his first year, the U.S. player pool has been thoroughly examined as Pochettino familiarizes himself with dozens of previously unknown options. Some recurring issues were understandable consequences of his continued chopping and changing. Others suggested he just didn’t have the players available to make his ideal system sing.
Often, a team that’s struggling to generate chances or results will flock to the wing for refuge. The wide areas are less congested than the central third, offering more open room for carries and give-and-go sequences that can quickly move upfield. It rewards players’ athleticism and instinct while helping advance in spite of a system that isn’t quite a well-oiled machine.
One finding from the Gold Cup was that Max Arfsten was not a natural answer at left back in a 4-2-3-1. Arfsten plays as an attacking wingback with the Columbus Crew, and he didn’t have the awareness or defensive composure as the ball neared the box. The same zone was repeatedly targeted at the 2025 Concacaf Nations League, when Joe Scally started in defeats against Panama and Canada. Thus far, there’s no proven alternative to Antonee Robinson on the left in a back four.
In this 3-4-2-1, Arfsten was playing a far more similar role to the one he occupies at the club level. His opposite number, Alex Freeman, plays his club soccer on the right edge of a back four. However, the 21-year-old has the mobility and positional awareness to play a more advanced role, as he often factors into the Orlando City attack.
For the first 15 minutes Tuesday, it was Freeman who was pinning Japan back with dribbles upfield. The opponent began to catch on, shifting its center a bit to its left to slow him down. Perhaps fueled by playing at the Crew’s home stadium, Arfsten had confidence and space to operate on the left, providing the game’s breakthrough with a well-looped cross.
Even at his defensive shakiest, Arfsten remained in Pochettino’s first team thanks to his attacking dynamism. He’s good value to win his attempted take-ons when dribbling, an invaluable trait to progress upfield while creating space for himself to cross. Asking him to lean into his bag of tricks is a less risky idea when there’s an extra center back to cover the defensive duties he was already struggling to handle. It also gets him into spots to make more actions like these, dribbling until he finds his crossing angle.
The use of a wingback helps solve for one of the player pool’s biggest deficiencies. While Christian Pulisic is the current generation’s greatest success and Tim Weah has forged a steady career in Europe, the U.S. pool is concerningly thin on the wings. Rather than forcing the issue, this tweak to a base 3-4-3 operates with two attackers beneath the striker in the channel — more like attacking midfielders than touchline-hugging wingers.
That’s great news for Pulisic, Weah and Alex Zendejas, who are each more natural goalscorer than chance-creating crosser. It’s also good news for Malik Tillman, Diego Luna and, potentially, Gio Reyna, who would still have an obvious home in the half-spaces. Pochettino could find his favored combination based on the matchup, offering simple tweaks to the format for each match.
The formation shift might also be a welcome change for his star pupil. As a left winger playing out wide, Pulisic can struggle with his decision-making in possession sequences and transition alike, needing to cut in-field and survey passing options while acknowledging his instinct to set up his own shot. In the seam, he has a bit less to mull over as he’s already at a shooting angle…
…or able to slip a ball between the marking defender and a center back being pulled out of position away from his striker, as he did here to set up Folarin Balogun for the clincher vs. Japan. Don’t underestimate the value of Arfsten’s comfort in this role, offering a needed off-ball run to put the right half of the backline in two minds and thus giving Pulisic a little more space with which to operate. That has a trickle-down effect on the striker, who could get a little extra room with two more scoring threats or creators in close proximity.
As Pulisic exited following the assist, he gave Pochettino an affirmative nod while his coach gave a wink and a nod. Seemingly, they won’t see a need to swap barbs about this change on podcasts.

After halftime, Pochettino told the TNT broadcast that he was happy to see his team getting used to “another system.” Given how it performed, we haven’t seen the last of it. So what does that change about the squad permutations heading into the 2026 World Cup?
The biggest question about how viable this 3-4-2-1 will be has to do with the position group most directly impacted: the midfield. No area of the field has been rotated more heavily and consistently under Pochettino, with the previous cycle’s set-in-stone baseline of Tyler Adams, Weston McKennie and Yunus Musah fully deconstructed to examine new options.
It goes without saying that two midfielders will have to cover more ground without a third teammate in the engine room. Sometimes, that’ll slow upfield progression until the ball sprays wide. Other times, it’ll allow opponents to take shots if they get behind the midfield and the backline is holding its ground, as Kōki Ogawa attempted in the 70th minute before seeing his chipped shot clang off the crossbar.
While line-breaking with dribbles and passes alike is still a major benefit, tirelessness and agility to follow a play as the ball leaves your proximity are even more mandatory in a double-pivot. It may mean more coordinated in-game rotation to keep legs fresh, or more trust in players who are used to playing in a two-man midfield (like Cristian Roldan, this camp’s late inclusion).
Playing with two midfielders is also a risk sheerly in terms of Pochettino’s personnel. The pool is pretty deep in central midfield; beyond the incumbent ‘MMA’ trio, Tanner Tessman and Aidan Morris continue to thrive since moving to Europe, while Johnny Cardoso, Sebastian Berhalter and Luca De La Torre have continued to warrant looks with the national team.
Almost certainly, two of the players named above will miss the World Cup squad; it might be three if Pochettino needs more center back depth. Considering the lack of surefire center backs who can be starters at an international level, he might want the safety of choice.

If the midfield represents the pool’s deep end, then center back may be its wading area. Chris Richards and Tim Ream are the only options who have continued to make the majority of Pochettino’s camps, with Ream a month shy of his 38th birthday. Mark McKenzie starts for Toulouse in Ligue 1, but was bypassed in both September friendlies for the previously uncapped Tristan Blackmon. Miles Robinson and Walker Zimmerman are holdovers from Berhalter’s core. Celtic duo Cameron Carter-Vickers and Auston Trusty both missed this camp, and with the Scottish side missing out on the Champions League, they may not get the big-game tests needed to work back into Pochettino’s plans.
Of the program’s fullbacks, most — from Arfsten and Freeman to Sergiño Dest, Scally and John Tolkin — are more comfortable going forward than doing defensive work. The only exceptions are Robinson and Freeman; both could serve as makeshift wide center backs to offer further wide options and variety in possession, or play more naturally out wide.
The story of the September window, narratively, was one of impatience: discouragement that the team didn’t look more ready for next summer’s close-up, and confusion about the continued vetting of fresh faces so close to a World Cup. To Pochettino, a career club manager, friendlies may as well be his preseason. A string of bad results will harsh the vibe, but the losses can be spun into positive if lessons were learned.
“It’s hard to be more consistent,” Pochettino said. “(This) formation is more simple to understand, for the players, than the formation that we started in (against) South Korea.” From there, he emphasized the change as a chance to “simplify things” and lean into his players’ strengths. “We have a squad that can fit very well in that formation.”
In that sense, the change in shape against Japan may have provided valuable validation of his trust in players like Arfsten and evidence that this new formation could fit his player pool best. There’s still a lot of work to be done, especially in midfield. But for now, the U.S. fanbase can see a sign of evolution under Pochettino — and, after such a tense aftermath to Saturday’s defeat against South Korea, that sure looks like some measure of progress.
