Javier Pastore's added-time effort secured Paris Saint-Germain what could prove a vital two-goal cushion as the French club beat Chelsea 3-1 in their UEFA Champions League quarter-final opener.

PSG opened the scoring at the Parc des Princes after four minutes when John Terry's headed clearance fell to Ezequiel Lavezzi and the Argentine forward thumped a half-volley past Petr Cech.

Eden Hazard grabbed a crucial away goal for Chelsea from the penalty spot after 27 minutes after Brazilian defender Thiago Silva fouled compatriot Oscar.

PSG restored their advantage on 61 minutes, however, thanks to a David Luiz own goal before Javier Pastore waltzed into the area and fired a shot past Cech at his near post in stoppage time.
