Once again, Goal.com's expert reporters will be on hand to provide you with in-depth coverage and analysis, but here's what they think may unfold on Tuesday and Wednesday.
KRIS VOAKES SAYS ...
Milan may well have held the Blaugrana last week, but doing so again at Camp Nou will take a monumental effort.
While I believe that the Rossoneri have enough of a forward threat to cause Barca the odd problem, there is also reason to be fearful at the back.
The likes of Daniele Bonera and Luca Antonini will have to deliver once-in-a-lifetime performances for the second time in a week if Milan are to withstand the inevitable pressure from the home side.
Expect the Serie A champions still to be in with a shout late on, only to eventually buckle. And for an extra prediction ... I tip Lionel Messi to score his first goal against Italian opposition from general play.
|Olympique de Marseille|
CLARK WHITNEY SAYS ...
Marseille put up a valiant effort at home last week, but came away with a two-goal deficit.
They visit the Allianz Arena with a near-impossible task: only once have Bayern conceded twice at home this season, and never have they lost by more than one goal.
L'OM will be forced to attack, and that will play into the hands of Bayern, who have an outstanding record in their own backyard.
The hosts must be wary of complacency, but barring a miracle, the Bavarians should have their semi-final ticket booked after the tie was decided last week.
LUIS MIRA SAYS ...
In the first leg at the Estadio da Luz, Chelsea were not exactly the better side, but were much more incisive, as Benfica missed the experience of Ezequiel Garay.
For the return leg, the Portuguese club's defensive problems have been further increased, with Jardel also in the infirmary, while Luisao and Miguel Vitor are in doubt for the European clash.
At Stamford Bridge, Jorge Jesus is expected to use Rodrigo alongside Oscar Cardozo to add more pace to the attack, which could see Benfica hit Chelsea on the counter, but the defensive problems will put the tie beyond them.
BEN HAYWARD SAYS ...
Real Madrid claimed a comfortable 3-0 victory in the first leg in Cyprus last week and APOEL were unable to muster a shot on target in that match.
At home, Jose Mourinho's men are likely to have things even more their own way.
With difficult league fixtures against Valencia and Altetico Madrid ahead, Mourinho may decide to rest one or two players for this match, but the Portuguese has promised to pick a strong team and they could run riot on Wednesday.
