Paris Saint-Germain edged a 2-0 victory in Le Classique on Sunday, when Kylian Mbappe was again the hero off the substitutes' bench as Neymar assisted Julian Draxler's second but was far from his best.
Mbappe was benched by manager Thomas Tuchel despite Edinson Cavani's injury, but the France striker came on after an hour at the Stade Velodrome and broke the deadlock within minutes of his introduction.
Ligue 1's leaders again stand eight points clear of second-placed Lille in the French top flight, but Neymar's disappointing performance in such a big fixture is a worrying sign as PSG head closer to a busy winter schedule.
