I'll do a break down prediction.
QF
Milan v Bayern: Bayern is not enjoying a particularly good season,
lying 4th in the bundesliga. Milan currently occupying 6th in serie
A, but is enjoying a winning streak in the league and closing on
4th place. They are also more consistent in the UCL this season
than Bayern. Although Bayern has the adv of playing the 2nd leg at
home, i think Milan will emerge from this tie as close
winners.
PSV v Liverpool: People are saying that Liverpool got lucky when
they drew PSV in the q-finals, but i beg to differ. PSV has been
pretty consistent in europe over the last few seasons, and the
experience accumulated should make them a tough unit to beat. They
also have the psychological advantage of having seen off an english
team in the previous round. Having said that, Liverpool should have
more hunger to win, as they are already out of contention for all
domestic competitions. The UCL is now their sole chance of glory
this season. And with Rafa Benitez at the helm, they can beat any
teams in knockout ties. This should be a close tie, with pool
getting some away goals in a close first leg, and finishing the job
at anfield.
Roma v United: This is the toughest qf tie to predict, due to
various reasons, namely because this is the first european
encounter between the 2 clubs. Adding to it is the uncertainty in
the availability of forwards in the United team in early April.
Records of both teams in recent european seasons hasnt been good;
First time Roma reaches the qf stage, and the first for United in 4
seasons. Considering the worst scenario for United, with only
Rooney and Smith the only available forwards for this tie, it would
be hard for United to carve out goals, esp the important 'away
goal' in the first leg. They also have the distraction of
maintaining their lead in the league, while Roma have no such
worries as they are lying comfortably in 2nd in the serie A and
have little hope of catching league leaders Inter. However, SAF and
his men plays a different game in europe this season, and they are
more tactically sound, as demonstrated in the tie against Lille.
Added to the fact that they are an overall more experienced team
and also have home advantage in the 2nd leg, they should just nick
this tie.
Chelsea v Valencia: This tie will go Jose Mourinho's men's way.
Suspension of key Valencia players from UEFA due to the round of 16
brawl against inter will aid the blues. Chelsea should be able to
build a good lead to go into the 2nd leg, and play out a draw at
the Mestalla. JM is hungry to beat his previous best record at
chelsea of a semi-final appearance 2 seasons ago.
SF
United v Milan: At this stage, league distractions and fixture
overload should prove too much for SAF's thin squad. By this stage,
forwards Saha and Solskjaer shoud be back in the team. But
ironically, this would also be the stage that they would bow out to
a superior Milan team.
Chelsea v Liverpool: Yet another Blues v Reds european tie. Rafa
has a slightly more superior head-to-head tie with mourinho in
recent seasons, but i dont see Mourinho falling twice to the same
opponent at the same stage of the same tournament. 'Revenge' in the
mind is their best element of success. Blues to edge out the reds
in this semifinal tie, and book a final place alongside milan
Final
Chelsea v Milan: I'm no Chelsea fan, but i got a feeling that this
might just be their year. How many times have u seen Jose Mourinho
lose a major cup final? (Correct me if i'm wrong, but according to
my memory the figure is zero, during JM's 3year reign in english
football) This will also mark the perfect farewell for 'the special
one'.... Too much drama?
