I would rather him use a 4231 where Acosta + Creative midfielder becomes the double, but Arena's 442 should honestly get us the 3 points tomorrow.
For 2018 when our squad is full, we can maybe put in 4231 with Bobby Wood swapped out for Dempsey, since dempsey is getting old as hell.
Yedlin in place of Zusi, and perhaps Villafana can stay as our Left fullback. Acosta + Bradley/Lletget as our DMs. A midfield of 3 with Nagbe on the left, Pulisic center, and im not sure who can play as our RM.
But then again Arena will probably not do that. He underestimates our defensive capabilities with an in form Brooks and Cameron and Yedlin. Our defense is usually dogshit which is why we usually go with a bunker 442 but we actually have a decent defense, short of our left fullback for the first time since like 2009
