Lyon bounce back to beat 10-man PSG
Turkey striker Mevlut Erding tapped in from a corner on 10 minutes to put visitors PSG ahead.
The Parisians then had defender Mamadou Sakho sent off on the hour for a challenge on Lyon striker Bafetimbi Gomis and Lyon fought back with a goal from close range by Gomis on 77 minutes and a header from Brazilian defender Cris three minutes later.
Seven-times champions Lyon, who lost their crown to Girondins Bordeaux last May, move up to fourth, nine points off the pace, while Paris drop to 14th after their third successive league defeat.
Bordeaux still top the table on 48 points from 22 games, despite being held to a 0-0 home draw by lowly Boulogne on Saturday, and hold a six-point lead over second-placed Montpellier, who beat Olympique Marseille 2-0.
