I gonna play final of the Champions League against 4-3-3. Seems to me that 4-3-3 could be really hard if played defensive with counters. This guy played against much stronger team in semi-final, had only 36% possession in both games, but won 2:1 and draw 1:1. Cant say that was only luck because the guy is in final now.

So, I have two tasks:
(1) I need strong defense, strong middle with DCM; AND
(2) I need strong wings
= Not enough players.

So, I decided to apply asymmetric formation. I pick the weakest spot in his defense and will play concentrating all attacks on left wing (my strongest and his weakest):
RD-CD---CD-LD
-----DCM-----
---CM---CM---
-----AMC---AML
---------ST---
If I see that something goes wrong with asymmetric formation I gonna substitute AMC to AMR (4-5-1 V) or AML to ST (4-2-1-2 NDi). This is final and I dont have pleasure of second try.
