It was the away side that created most of the chances in the first period, but they could not make the breakthrough as it remained 0-0 on the night.
PSG had the lead after 50 minutes when Javier Pastore drove into the box before clipping his effort into the back of the net. However, Barcelona levelled on the night with 20 minutes to play when Pedro found the bottom corner from inside the box.
The French outfit continued to force the issue in the latter stages, but they could not find the second as Barcelona advanced courtesy of away goals.
