Or maybe something like this tasty 3 at the back look:
-------------- Wright
--------------- Pulisic
--------McKennie-------Reyna
Jedi-----------Adams--------- Dest
-----Ream-----Zimm-------CCV
-----------------Turner
C'mon, there's no way we see 3 at the back. Furthermore, it takes an attacking player off the field in lieu of Dest and Jedi playing up higher. I'd rather have Aaronson, Gio, and CP on at the same time somehow.
Aaronson's not really an attacking player. His G+A/90 and chances created/90 are below average for a Premiere League midfielder (Musah, for all his great ball progression, isn't the finished product as an attacker either). Aaronson's best trait is his pressing, but do you think Iran is going to try to play out of the press all that much? I think they'll be happy to play it long.
And, yeah, one big purpose of the formation is to allow Dest, in particular, to play higher up the field without worrying so much about his defensive responsibilities. If I had to bet on a guy to score from outside the box, Dest is my first bet. I don't think this formation sacrifices a bit of offense. I think it sacrifices some ball-winning in the middle of the field, but that's because I think Iran is going to bypass the midfield.
