London - 10-man PSG have dug deep to qualify for the quarter-final of the Champions League at the expense of Chelsea on away goals, after extra-time, in their Champions League last 16 second-leg match at Stamford Bridge on Wednesday night after the aggregate score was left at 3-3 after extra-time.
The match went to extra time after a 1-1 draw during regulation time after the first leg was drawn with the same score line.
PSG had Zlatan Ibrahimovic sent off for a foul on Oscar in the first half and fell behind when Chelsea defender Gary Cahill fired home from an 81st-minute corner.
But the visitors equalised five minutes later when substitute Ezequiel Lavezzi's corner teed up former Chelsea defender David Luiz to crash home a towering header via the underside of the crossbar.
Chelsea prevailed on away goals when the teams met in the quarter-finals of last season's competition thanks to an 87th-minute goal in the second leg from now-departed striker Demba Ba.
They thought to have seen a path through to the last eight in the first half of extra-time after PSG captain Thiago Silva handled the ball inside the 18-yard area to hand the hosts a penalty.
Eden Hazard calmly slotted the spot-kick beyond PSG's Italian goalkeeper Salvatore Sirigu.
However, Silva would atone for his earlier error to tower above the Chelsea defence in the 114th minute to nod a Thiago Motta corner past Thibault Courtois.
