Decent point but I would overplay it too much really, don't know how much you can read into it. I'm sure if theon tries hard enough he can find instances of a diamond beating a formation like yours. Th first leg was 4-1 in Milans favour rignt?
Really don't think it proves that your formation is suited to counter Theons, even though that's a point I am finding myself agreeing with. Haven't really heard how the threat of Carlos and Alves is going to be nullified, looks like your best weapon right now.
The threat is largely nullified because the wingbacks need to defend - they can't constantly bomb up the pitch because that would just leave Desailly and Blanc 2 vs 2 against Crespo and Shevchenko. If Carlos and Alves commit too often that plays right into Iniesta and Shevchenko's hands, they would just occupy that space.
Don't forget unlike Maldini and Thaigo Silva facing one striker, Desailly and Blanc are facing two. You can't just keep sending fullbacks forward against two strikers of that quality, especially because Iniesta is there to join in.
I really think people are underestimating the impact playing two strikers have - his wingbacks cannot keep going forward, he doesn't even have an assigned defensive midfielder for feck sake! If Blanc and Desailly keep getting isolated 2 vs 2 then this game is over.
I have given loads of plans to combat his strengths Fergus - 1) Ronaldo vs Maldini 2) Gattuso/Cafu vs Figo 3) Sheva/Crespo exploiting his wingbacks if they get too adventurous.
You should question him on how he will stop Pirlo, Iniesta, Shevchenko and Crespo.
