dell's on the right track, but I'd use 3n-0-3n-3w-1, red arrows on the AMC and central MC, blue arrows on the wingers, focus middle, counterattack + normal or defensive.

That will give you a 3-2 advantage in midfield (possession ++) Your wingers will pull off his outside defenders, His DMC will end up splitting coverage between your AMC and MC^, leaving your AMC and striker to exploit the gap between the defenders in the middle.

You only need 3 defenders to counter his lone ST, especially with the midfield advantage of 3 MCs vs his 2. His MR and ML become mostly irrelevant, (and would be partially countered by the blue arrows on your wingers anyway)
