How to Win Against Any Formation?

[fedja]

Hi guys, it's my second season in top eleven. First season i won both cup and ligue. This season i'm leading my league with 6-0-0
In cup i will face one level 7 player in 4-5-1 V style:

ST
AML AMR
MC MC
DMC
DL DC DC DR

i'm pretty pissed because i will face a guy with 5 levels more than me... but that's the way it is.
So i came to ask some advices, i read a lot of stuff here before to come to ask your minds.
In one very interesting tutorial one guy (ADEL GAMAL) is telling that against 4-5-1 it's nice to use 3-5-2 and few lines later he's also telling totally opposite :"against 3-5-2 it's good to use 4-5-1...." LOL

WHAT TO DO? How to win against this f****** 4-5-1??? Usually i'm playing in 4-1-2-1-2 diamond but this Formation is very weak on the wings... Need some help
