Hi Adam read some post above, I finally played with 4-3N-1-2 and easily won 5-0 at home the return match in League with an opponent who beat me 1-0 at 1st match in wich I started with the same 4-2-2-2 and later tried to change something passing to classic 4-4-2.
And I have 5 or 6 medium quality points more than him!
Beyond this League match, I've faced in Champions League QF another guy using the 4-2-2-2 hexagon wich quality is similar to League opponent.
At 1st leg, me playing away, I used the 4-1-2-1-2 narrow diamond and it was a 1-1 draw.
At 2nd leg I used 4-3MC-2AML/R-1 and it was another 1-1 draw, I finally won the leg at penalty shootout.
So, try maybe the 4-3N-1-2
