I had my last competition match today against 3n-5-2. Started the match with butterfly (as the table suggested) , normal mentality, through the flanks, zonal marking, mixed passing, no offside trap and no force counter. Had red arrows on DL, DR, AML and AMR. After the first half it was 2-1 for the opponent. So I changed it to 4-5-1 V, again arrows on DL, DR, AML, AMR. Changed normal mentality to attacking and the rest the same. Played the opponent away and he got no chances to score since i changed it. Won 5-2. So if you play against 3n-5-2, I would suggest 4-5-1V!
