I think liverpool have a decent chance this year, probably better then the last time. We've already knocked two of the strongest teams out and it was both based on solid teamwork and organisation, something manu lacked against milan. Ive mentioned this in another thread aswell, but liverpool play a totally different kind of game to manu and have totally different players aswell. The midfield is far stronger physically, with gerrard, alonso, maschorano or sissoko. They also continue to run and harry the whole game, which nobody really does for manu (carrick wanders about, and scholes should stay away with his tackles). Also we have 2 strikers that really are annoying to play against, crouch through the air and holding the ball up and kuyt that, like the midfield, continually runs and harries the defenders. And i think its that which will be the best tactic to get under milan's skin and annoy them. Watching the two semi's everytime manu started to press higher upfield and harry their defenders milan lost possesion a lot quicker and easier (the final 30min at ot and the first 20min of the 2nd half at ss).
Also liverpool know how dangerous kaka is after he ripped alonso a new arsehole last time we played so i would expect the team to be better prepered. And the defense will only have 1 striker to defend (excluding kaka who now plays more up front then last time but will still be a player that the midfield will have to pick up as his speed will easily get the better of both carra and agger) whereas in 2005 it was scheva and crespo.
And as has been said, liverpool are far stronger this year then last time, and milan (when under pressure) definitly have fatigue issues with their overall age.
Dont know what way it will go though, think if liverpool can stop kaka they will have a good chance at nicking it. Otherwise i could see a comfortable 2-0 win for milan.
