4-4-2 or 4-5-1, it's just a matter of getting the most of the squad at a given moment(match).
4-4-2 will work against your group a teams, if the lines are close to each other. meaning, that the team operates as one unit. so that there always are 2-3 players near the ball, both when defending and going forward. in doing so, the extra man in midfield is rendered ineffective. the numerical superiority is nullified.
i'd say it doesn't really matter which formation wenger choses. it's not an important issue in the big scheme of things.
I agree in principle but it's also about having the right players in order to execute ANY formation, or having the right formation for your available resources.
