It's not he best of ways to counter 4-4-2.results will be random to say the least .when playing 4-5-1v vs 4-4-2 u waste the utility of one player by playing him in DMC.it is useless as opposition does not have AMC to defend against.it will also be a deadlock in CENTRAL midfield as both teams will have 2 midfielders there and also as the wingers are in advanced positions in 4-5-1 v style,ur full backs will be exposed to opposition wingers regularily if opponent plays 4-4-2 down both flanks
