again, i cannot help you much if you didn't give enough information
at least the different of team strength.
i only give advice to you as below
i) you need DMC to mark opponent AMC
ii) focus your attack through the middle because he only got 1 MC, no DMC, 1-DC, his middle is very weak
iii) you need to protect your flank also
iv) best formation to counter it is 4-1-2-1-2 (Narrow diamond) short pass, through middle
