What the hell I did wrong?

DMC and DCs rating has been 6. All the rest got 6 or 7 except an 8 for the gk and 5 for both wings (ML and MR).

Anyway, in return leg I set a narrow diamond and 15 minutes before the end the result was 2-0 for me.

Then I made the final attempt changing to 3N-3N-2-2 (just like dv8r advised) but then he scored 2 goals in last 10 minutes.
Maybe I shouldn't have changed the formation, who knows..

So, after two matches it seems that center-based formation, with AMC and DMC, is the best to face a 4-3-3.
The passing was normal, in the middle, and the mentality was normal with 4-1-2-1-2 and offensive with the second module, both with offside trap)
