Pulisic has been less effective for the USMNT and Dortmund when deployed as a wide MF in a flat 4 midfield. A 4-4-2 with a flat four midfield is how Arena lined up against CR at home and I think against Honduras away. Stoger did it too and I think Favre did it once early in the year. That GB attacked in a 3-4-3 (3-2-2-3) and 4-3-3 hopefully means he doesn't see that Arena 4-4-2 as effective for Pulisic and that Pulisic's effectiveness is important. I think Pulisic could be utlitized well in the position Baird played, Ebobisse/Arriola played, or Djorde played. If I had to guess, I think GB tries him in the Djorde role first, where he is a 10 on offense and a forward on defense. Sort of how Sarachan used him against England and Italy. I would expect, with time and practice, Pulisic will move in between all these positions in a game.
