Before the tidal wave of "pussy tactics' starts:
The formation was too aggressive. It wasn't pussy. It was a mistake to play with 2 CMs and not 3. It's not a pussy tactic if you are playing with 4 midfielders instead of 5.
We couldn't grab possession because we didn't have enough in midfield. Because we had one too many attackers on the field. He went with Khedira-Pjanic in front of the defence which is basically the most aggressive and risky thing you could do.
This is actually the most common theme with Allegri in CL. It's not pussy tactics, it's the opposite. It's why we got smashed in the 2nd half vs. Madrid. He risks a lot to defend with 8 instead of 9 and hope our attackers can put chances away.
And still it basically worked as we should have had a minimum 3-2 result.
To be honest, when we went up 2-0. If he switched to a 4-3-3 with Costa on LW to utterly rape Aurier, the game would end 4 or 5 nil.
