4-4-2 works. but the best is formation that close his attack and make your attack free in position:

DL DC DR
DMC(↓) DMC(↓)
MC MC
AML AMR
ST

base on the same defence (dl dc dr dmc dmc) you can build also other possible formations like
MC MC
AMC
ST ST
(attcack from middle)

or Tower formation as mentioned above.
