As he has AMC,so should have one DMC..
I would like to suggest that use

---------------ST(up)-----
-AM(up)L------------------AMR(up)
-----MC(down)--MC(down)---
------------DMC----
-DL---DC-------DC------DR

Or if u have strong defender then use


-------------ST---ST----
---------------------------------
-ML-MC(down)--MC(down)-MR
--------------DMC---------
-----------DC-DC-DC---
