Advice for 3W-4-1-2

[Nicky]

Cup's playoff, first leg at home.
I'll play against a team a little bit stronger than me with this module:

DL----DC----DR
---------------
ML-MC---MC-MR
------AMC-----
----ST--ST----

Considering that I've a very strong defense but I'm conceding too many golas, what module would you suggest to use?

With a narrow diamond I''l be stronger in the middle but weaker in the flanks.
