Auba's sort of the opposite problem of our recent strikers (despite the gaffes today). He's actually is an above average finisher but his contributions to the play of the team is pretty terrible. Broja really ought to come on pretty quickly here.
They were the better side after switching to 4-3-3. 3rd game in a row where Potter starts a really dodgy ill fitting initial lineup.
Broja on for Auba early and then Pulisic should be on for either Sterling or one of Jorgi/RLC depending how the game is going. If they have good control go 4-2-3-1 if not stick with 4-3-3 to try to combat in the middle.
