The path to the Champions League final has been set. The draw in Nyon has thrown up the mouthwatering prospect of a Barcelona-Real Madrid final in Munich on May 19.
Before that, however, the two great Spanish rivals have to negotiate two other ties. Barca continue their defence against AC Milan, whom they faced in the group stage, while Real have the far more appealing task of playing APOEL Nicosia.
Assuming they both go through, Barca will play the winner of the quarterfinal between Benfica and Chelsea, while Real will play either Marseille or Bayern Munich in the last four.
Here are eight key battles—two for each tie—that will decide which four teams make it to the semifinals.
