I would dont use the offside trap if the opponent has am's. In this case amc.
The amc can be very dangerous for you. So i would ever play with dmc against a amc.

The 4-4-2 C is not really an attackformation. I dont know the word at the moment but it is a save formation. Mostly played from managers that have not much time for their team. Its save with 4 man defence and mids. But there arent any attackingmids am's so the best way to play this formation is normal mode.

And if you go for whole pitch i would go for hard tackling because you dont want the opp in your half.

Just a few thoughts.
