In both ties with Milan we had the vast majority of our defensive line out.
Of or first choice back 4 we only had Evra available in first leg, and Vidic in second, who wasn't match fit in the slightest but lack of options due to extent of injuries forced us to play him half fit.
That's why we struggled to deal with theit attack in both games.
No guarantees we'd have beaten them with Ferdinand, Vidic and Neville their - but its safe to say that we would have conceded less over the two legs and dealt with Kaka a hell of a lot better.
