Paris St Germain were dumped out of the Coupe de la Ligue following a shock 2-1 defeat to Guingamp at the Parc des Princes.
The holders, who have won the competition for each of the past five seasons, appeared on course for a place in the semi-finals when Neymar broke the deadlock shortly after the hour mark.
But Yeni Ngbakoto converted a penalty with just nine minutes remaining, before Marcus Thuram netted another spot kick in the third minute of injury time to secure a famous win for the visitors, who are bottom of Ligue 1.
Remarkably, it marked the first time PSG have been defeated in a domestic cup tie in 50 matches.
