4-4-2 is balanced formation . 3-5-2 V (or 4-5-1 V) it's works to against 4-4-2. BUT if ur opponent puts red arrows on ML and MR, your 3-5-2 V is not effective. and your 3 DC will be easy to penetrate. always use 4 back (2 DC, DL, DR) to againts 4-4-2, dont ever use 3 DC without DL and DR !! u need through the middle and i suggest 4-1-2-1-2 narrow diamond to beat 4-4-2 classic. offensive mentality (home) and normal mentality (away),short passing, through the middle, zonal marking, own half. normal tackling. no offside trap and force counter. and u can put red arrows on the DMC and AMC if you need to score. Good Luck
