You must have three defenders, so I would place 3 DC to mark the ST, then 2 or 3 ST because this is a very defensive formation you're playing against. If you're feeling confident, then something like a flat 3-4-3, but push the ML/MR up to AML/AMR. I would actually play 3-5-2, maybe flat, maybe flat 3-4-1-2 with an AMC in the hole.
