If Liverpool were to win, it would be in a penalty, in my opinion.
Milan was very good against us, but it was similar to how we destroyed Roma, it was a day that everything worked out, so Liverpool does have a chance. And to be honest, the Liverpool side is probably more suited to the possession chess game then our swashbuckling style. But the scoreline, if Liverpool were to win, will be much closer to 1-1 or 0-0 then the scoreline last time.
But Kaka had been on fire, as has Gattuso and Ambrosini, and I don't see the Liverpool midfield winning out for now. If Milan play to their standards, I'll say 2-0 to Milan, and Maldini signs off his career with a CL trophy.
