Edinson Cavani bailed out Paris Saint-Germain and the dismissed Neymar with a stoppage equaliser to secure a 2-2 draw against Marseille in Le Classique.
PSG trailed twice and had looked destined for a first defeat to their fierce rivals since November 2011 - with Neymar sent off for two bookable offences – before Cavani curled a dramatic late free-kick into the top corner to rescue a point.
Marseille led through Luiz Gustavo in the first half, before Neymar equalised, and then again moved in front when Florian Thauvin lit up a dreary second half.
