You have few option to beat that formation bro.
4132 ( 3 mc )
4312 ( 3mc amc 2 st )
4231
41212
You also can play 352 (like 451 ) but with 2st, because he play with only one st.
But you choise because i don't know your team, what style you play and that stuff.
My opinion is try to play 3dc-1dmc-2mc-amr-aml-2st if you have wings player.
