TBH that doesnt look illegal to me. 1-2 player on each side. at least 1 CM/CDM. at least 4 players above the half line
not too sure though as i dont really pay attention to formations
True. It's an legal formation, it's juast seems asymetrical formation. On the cup i against that formation with 3-1-4-2 flat. And won 1-0 at the home and away.
YOU're MANAGER, YOU MANAGE
Congratulation Arsenal!!
