TH: That he has a vision for the way this team should play. Setting up an international side, historically, has been rather tricky. There are limited windows to work with your team, so trying to set up the kind of positional play - hello, Pep Guardiola - that defines most club sides is tricky. But it seems that Poch is set on doing it. For now, that's pretty exciting. It might not work all the time - Panama certainly exploited a weakness or two - but there's something cooking here. Talk to us in November once he has a fully fit squad.
JS: He values workrate and has drilled tactical ideas into the squad during this camp. The most notable was Musah playing as a right-sided midfielder, allowing space to open up in the center of the pitch, while seeing Brenden Aaronson tuck inside at times.
That, and he's cognizant of minutes. Sending home a handful of players due to minor knocks and/or allocation of time played is smart and respectable. A nice change of pace there.
AL: The confidence that emanates from the former Spurs and Chelsea manager on to the pitch. One of things that immediately stood out about Pochettino is his self-assured nature, and throughout the match it resonated.
The other thing was the implementation of ideas. Early on, the U.S. used a familiar 4-3-3 lineup but once kickoff happened, the roles had changed almost instantly. Pulisic was playing higher up in a second striker role and Musah started in center mid, but was shifted all over the right-wing flank and impacted all three phases of the game. While those shifts weren't always sustained, especially as Panama asserted itself, it was impressive considering the team had only four days of practice.
RT: It's less about Poch and more about how the players react to him. It's clear that Pochettino has walked in and instantly put his stamp on things, whether that's training drills or tactics. The players, from Day 1, seemed to have bought in and embraced the new order. Pochettino has a name and resume that commands that respect, but, in these early days, the execution has been there. The biggest lesson so far? This transition might just move a bit quicker than many expected.
