Guys i have the second leg of cup and i will play at home.
In the first leg i won 1-0 but he was playing 4-4-2 narrow diamond and 4-5-1 V style me...(it's my fault if I haven't score more)
Within 2 hours i will have the second leg and he changed the formation.
he play like this:

-------ST---ST
---------AMC
------ MC---MC
-DML------------DMR
-----DC-DC-DC-----

If he play with red arrows on both DML and DMR is some sort of 3-4-1-2
I Don't know if i should play with an AMC too or avoid it and play of the flanks.
I've never faced a such formation, so any advice is welcome.
