Since Kaka and CR are gone, who will be Milan and Utd's X factor?

i'm a manchester united fan and i think they will do the old typical thing that man united do concede early due to a scrappy goal and be chasing the game until it gets till about 75 minutes when someone like wayne rooney or valencia will have a good ten mins and someone like owen or berbatov will end up scoring late on personally 1-1 in the away leg at at old trafford i think we will beat them 3-1.i still hope becks scores though at old trafford
