I understand that you mean 3-3-1-3 wide. I'd use 3-5V-2. Its a very versatile formation. Gives you everything you need. If your team is better than his then choose attqcking mentality. If his team is stronger use normal, maybe even defensive mentality. Passing mixed, tackling normal pressing own half, zonal marking. No offside trap no counter attack. Red arrow on your DMC ams red arrows on your AM's. Blue arrows on defenders.

Also, a good tip is to be onkine as the match happens. That way yoi get that extra 8% possesion which can make a difference.

Hope this helps

If you find yourself losing, change to 4-5V-1 with normal mentality. That extra defender will help a lot.
