I love the 3-2-2-2-1 formation, doesn't matter which areas are wide or narrow, because it covers simply everything, and you can easily switch your focus between the centre or the wings with the right personnel.
For this particular one, I've heard it called the butterfly, you can see he's very attack minded down the wings, DML/R and AML/R compared to a standard 4-4-2's DL/R and ML/R. Therefore, you should also attack him down the wings, as that's where his defence will be most exposed, especially on the counter.
It does depend who's better, but I'd actually suggest you play exactly the same formation as him. The midfield will be matched up perfectly, with 3 DCs against an ST on both ends of the field.
