Ligue 1 - Round-up: PSG stumble into semis
Lacklustre holders Paris St Germain stumbled into the French Cup semi-finals after two extra-time strikes sealed a 2-0 win over second tier Le Mans.
Second division Angers also won through after ending the stunning run of amateurs Chambery while Ligue 1 leaders Lille were meeting FC Lorient in the final last eight match.
Top-flight Nice progressed on Tuesday with a 3-2 extra-time win over Stade de Reims.
A slightly weakened PSG team laboured at a half-full Parc des Princes until 17-year-old forward Jean-Christophe Bahebeck made a name for himself with his first club goal, expertly driving in at the near post on 108 minutes.
Neeskens Kebano, another of PSG's much-talked about youngsters, bagged the second three minutes from time in a game where both teams had been reduced to 10 men.
Amateurs Chambery, the first fifth-tier club to eliminate three Ligue 1 sides, finally met their match when they lost 3-0 to Angers.
Chambery had wowed France by knocking out top-flight Brest, Monaco and Sochaux in previous rounds but they could not rouse themselves for another shock against more modest Angers.
The game was moved to a bigger stadium in nearby Grenoble given the interest Chambery had generated in the alpine community and although they started brightly, Henri Saivet, Sebastien Renouard and Diego Gomez sent the visitors through.
