I use 4-3-3. I always struggle against 4-4-2 Classic. Recently loosing 3-0 to a mate of mine using 4-4-2 (attacking down the flanks). Not sure what other orders he used, but he is rated 23.5 to my 25.5.

I had 8+ bonus possession, playing away to him and still got whipped. Drew my first game against him at home 2-2.
