A couple thoughts on why I think this should be an ideal fit.
1) Poch plays a pressing style not too unlike what Berhalter ran, but better. The Uruguayan side that gave everyone so many problems with their press deploy what Poch runs. Poch learned it by playing for Bielsa. I think our youth and speed, especially at the forward and midfield lines, are ideally suited for this type of a style and their prior familiarity with Berhalter's press should make this an easier transition even if his press and some of his principles are a little different. An easy transition is important with only 2 years until the next WC.
1b) Somewhat related to the first point is my belief that McKennie will thrive in Poch's system. We've talked the last couple years about how he seems to have lost his edge at times and doesn't command the center of the park like he once did. I think Wes is the ideal fit for Poch's system b/c he's got a high work rate and is a physical presence in the middle, which is a necessity in his press. The nasty McKennie that bows up to Mexican opposition and gets in their heads will be able to come out more under Poch. Poch's press creates turnovers high up the pitch, which results in a higher percentage of possession in the attacking third and greater chances on goal, but it requires a superior central midfielder capable of a high work rate and physical presence to generate those turnovers. A press like Berhalter's that relies on the wings and outside backs to defend high, but surrenders space in front of the center backs doesn't apply as much pressure and doesn't suit McKennie's skillset nearly as well. And I believe a strong Wes in the center of the park makes the rest of the midfield much better.
2) Poch will have very high standards, but he's always been known as someone players enjoy playing for. The players' support is probably the single greatest reason Berhalter was brought back. The players will love plying for Poch, but Poch will lift them to a higher standard of excellence than Berhalter established without having to be a hard charging disciplinarian to achieve it. Someone too caustic, like a Conte, would have mixed with our players like oil and water. While I wish the players were more receptive to a disciplinarian who could bring a higher level of accountability, I think Poch brings the right mix for our group. He knows what winning football looks like to an extent Berhalter has never been around and he'll immediately raise our floor for expectations as a result.
3) His stint last year with Chelsea demonstrates his ability to make a quick turn-around, which is what we require given the 2 year timeline to the WC. It may start out a bit ugly like the early part of his Chelsea tenure, but once the players figure things out I think things will click in a way that they'll be reaching near peak potential by the summer of 2026.
