Best one I've tried yet (from memory)
1 good, strong central Defender on Challenge Keeper
4 other Defensive players on STAY BACK
1 Offer Short
1 Lurk
1 Go Forward
1 Attack Ball From Deep
Your 3rd or 4th best header (preferrably one that isn't too tall but has good jumping+heading) on Attack Near Post
Inswung corners on near post by anyone except At Near Post or Challenge Keeper-guy.
Netted me 30 cornergoals in 28 matches, had to remove it because it totally broke the game for me.
Right now playing with a more balanced one that is 3 players stay back, 1 player Challenge Keeper, 1 At. Near, rest go fwd.
