Carlo Ancelotti suffered his first competitive defeat as Paris Saint-Germain manager when the Ligue 1 leaders lost 3-1 at home to Olympique Lyon in the French Cup quarter-finals on Wednesday.
PSG, unbeaten since Ancelotti took over from Antoine Kombouare in December, took the lead through a Nene penalty but Lyon struck back before the break with goals by Kim Kallstrom and Lisandro Lopez before wrapping it up with a Bafetimbi Gomis penalty in stoppage time.

Stade Rennes, who claimed a 3-1 win at 10-man Valenciennes earlier on Wednesday, will visit third division side Quevilly who reached the last four by beating Olympique Marseille 3-2 after extra time on Tuesday.
"It was a great first half. Then we had to sit back in the second half because Paris were really strong but we were disciplined and that's why we held on. Hats off to the team," Lyon coach Remi Garde told France 3.
PSG went ahead in the 19th minute when the hosts were awarded a penalty after Samuel Umtiti handled the ball.
