Christian Pulisic is the U.S. Men’s National Team best player. You will find very few people trying to debate that point. And Gregg Berhalter knows it.
That is why he attempted to use him as a central attacking midfielder during the Gold Cup. Berhalter wanted Pulisic on the ball as frequently impossible, such that he could impact the game on a regular basis. The logic was sound, but it reduced the number of situations that Pulisic could unleash his best skills in: dribbling at a defender in one-on-ones.
And so, this September, Berhalter moved Pulisic back to the flank, where the American may receive the ball less often but will have the opportunity to dribble at and past exposed defenders with speed and skill.
