John James, I am *not* the best person for formation advice, there are many more clever people on this Forum.
I normally play Maple Leaf, defensive, press whole pitch (if your players don't have high physicality this will make them tire fast though), arrows forward on wingers.
3 4 3, I might change to 3N 1 4 2 to meet them in the midfield, if they are weaker I do normal instead of defensive.
