The 2-2 draw between the pair in last week's quarter-final first leg had handed the advantage to the Catalans, but with star player Lionel Messi only starting the return as a substitute due to a hamstring injury, they seemed nervous throughout and PSG deservedly went in front just after half-time through Javier Pastore.

However, with Messi summoned from the bench, Pedro fired home 19 minutes from time to send Barca into the last four.
