Its very defencive I know so you must make the choice of either going for the win all out or be conservative and stay defencive and try to nick it on the counter!, I have played this formation a few times and had actually done really well using 4-4-2 or staring 4-1-3-2 and switching to 4-3-3 at HT if im not making any in roads. You have to take into account both teams strengths, if he is a stronger opponent I would play safe to start with.
