As Nik mentioned, there are several different options for playing against 4-4-2. It's not a guaranteed win, but you should have a slight advantage.
if you're stronger, mirroring isn't a bad idea as madflo suggested above. Since if your both playing the same tactic, he has no advantage.
Personally, I like the Christmas Tree (4-3w-2n-1) or 4-3w-1-2 when the opponent is passing down the flanks. Since he isn't trying to attack my middle, one MC (down arrow) should work fine. A DMC instead of MC, should do the trick as well.
