The United States men's national team arrived at this World Cup carrying a new edge - and after a commanding 4-1 opening win over Paraguay in Inglewood, they insist they are ready for the grind of what follows. Next up is Australia on Saturday at 5am AEST, and nobody in the American camp is under any illusion about the kind of afternoon the Socceroos will be looking to serve up.
Much of that readiness traces back to a scrappy 2-1 friendly win over Australia in Colorado last October, a match that turned into a genuine physical examination. It was the kind of contest that draws little broader attention - much the way a casual fan might stumble across a racing post greyhound card between the main events - but for Pochettino's group, it proved formative. The Argentine coach tore into his players at half-time, furious that the Socceroos were dictating the game's physical terms while the Americans wilted. Christian Pulisic left injured. The message from the touchline was blunt: stand up or be pushed around.
The players responded. The second half of that Colorado game became a battle in its own right, the match ending with a combined 19 fouls and two yellow cards. More importantly, a lesson was absorbed. "Watching that game last year, you could see they were up for it," said midfielder Sebastian Berhalter, whose father Gregg previously served as US head coach. "They were putting in challenges, and I think that's one of the reasons Mauricio had that half-time rant, and said, 'These guys can't kick us around.' I think he was right."
Pochettino Instills American Identity From the Outside
It is a curious and telling dynamic: an Argentinian coach teaching a generation of American players what American sporting identity ought to feel like. But Berhalter is clear about how Pochettino has gone about it. "I think one is that we're American. We don't take s***," Berhalter said. "Even though he's Argentinian, he has that mindset of, like, 'Look, this is what we do, and this is who we are, and this is what America is about.' So I think he just, you know, even from an outside perspective, he showed us Americans what we're about. He really drilled that into us."
Pochettino inherited a programme that had lurched through disappointing cycles - failing to qualify for the 2018 World Cup being the most damaging low point - and while the results under his tenure have not always been convincing, the shift in mentality has been visible. The Paraguay win was played with assertion and directness. The Americans looked like a team that believed in what they were doing. Winger Tim Weah captured the mood simply: "That game in Colorado was fun. It was aggressive. I think from that game, we've changed a lot. We've gotten a bit more aggressive as well."
Pulisic Fitness Clouds American Selection
The one genuine concern heading into Saturday is the fitness of Christian Pulisic, the team's most creative and experienced attacker. He was restricted to the first half against Paraguay due to a calf problem and has trained separately from the main group for two consecutive sessions. His availability - and if available, his capacity to last a full game against a combative Australian side - remains the key question for Pochettino as he sets his lineup.
Sebastian Berhalter, however, offers a credible alternative option. He made his World Cup debut when he replaced Pulisic at half-time against Paraguay, and he showed enough to suggest he can handle the tournament's intensity. His reading of the Australia match-up is straightforward and unafraid. "It's going to be a physical game, but a fun game, and we're excited," he said. "They are going to fight. We like teams that have that brotherhood, you know? We like teams that you can see they're hungry, they want to fight."
A Rivalry That Could Define the Group
For the Socceroos, who carry their own legitimate World Cup ambitions, Saturday's match is equally pivotal. Australia have proven over recent tournaments that they are more than capable of causing upsets, and their high-intensity, combative style will test whether the Americans' new mentality holds under real tournament pressure rather than in a mid-cycle friendly.
If it does, and if the US can add another strong result to their opening win, Pochettino's project will gain significant credibility at the most important moment. This is a young American squad that has been told - and now largely believes - that they belong at this level. Saturday morning will tell a great deal about whether that belief is justified.
