Counter formation against 5-2-1-2

I got a final match in Champions league tomorrow, I need a counter formation against this:

Attachment 7364

Thanks in advance! :3

Against 5 defenders I normally play 4-4-2 long ball but I would probably consider 3-5-2 v style in this match.

If you go with 3-5-2 play mixed passing, you wanna get the ball beyond his defenders.

How about 3- 1-4-2 ? Could it counter 5 2 1 2 ???
