Never ever saw 4-3-3 survive 3N13N2W1. To me, as long as any formation has such a deadly counter and so easy to be put in place, it is doomed. Two weeks ago, I beat 5-1 a formation that was 35% superior with manager present. I do not think this could have happened if he played 4-4-2 or 4-5-1 V for instance. I wish I'm gonna face many 4-3-3 in the future.
