Goals from Zlatan Ibrahimovic and Serge Aurier have given Paris Saint-Germain a 2-1 lead over Lyon at half time.
Ibrahimovic led the PSG attack from the opening whistle but his shot was saved by Anthony Lopes early on.
The Swede opened the scoring just seven minutes later though when his shot from the right side of the penalty area nestled into the back of the net.
Aurier doubled the lead with the next attack, heading in from close range after Angel di Maria's corner.
Rafael attempted to get Lyon back into the game in the 19th minute but Kevin Trapp was equal to his effort.
Lyon did pull one back in the 24th minute when Jordan Ferri's shot found the bottom left corner from 20 yards.
Clement Grenier had a chance to equalise a few minutes later but his long-range shot from a free kick went over the crossbar.
