I've always preferred overloading one side of the pitch when facing 442. single st on the right or left channel with an amc centre. You must exploit the flat nature of 442 with triangles, if you are going offside lots, use short. If you are losing possession in the centre of the pitch, use long passing as he is likely pressing high. No one formation is a guaranteed vs balanced formations like 442 but you must interpret the match statistics and game flow to determine your course of attack. i would recommend a formation with an amc though to create space for your other players.
