It's quite a defensive unit.

3-6-1 V or 3-5-2 v.. As told by a very experienced user, I played against a team 3 levels higher and drew the home leg 0-0 and lost 4-2 in the second leg. These are good results against a much better team so yeah... I reckon you should go for the attacking since all he's doing is sitting back and there's no point having much in the way of defence if your players can handle it
