How can i beat a 3-5-2?

[Robwin]

Hey, I'm up against 3-5-2 and I lost 1-0 away using butterfly and me being the stronger team (slightly), what arrows/orders should I use?

I was using attacking, down both flanks, own half, normal, mixed, zonal, no offside and no counter attack with red arrows on AML/AMR, was I just unlucky or should I change something?

While I'm at it, should I let my ST with 36 crossing take corners or is it worth changing a DC for another DC with slightly worse defending stats, 22 crossing and corner specialist? All my players are always on 90-99% condition and superb morale for important games like this so that wasn't the issue in the first leg. I also watched the game (he didn't) used max win bonus and no players are out of position.
