Guingamp, France (SportsNetwork.com) - Lyon returned to the Ligue 1 summit for at least 24 hours on Saturday as the club notched a 3-1 win at mid-table Guingamp.
First-half goals from Nabil Fekir and Alexandre Lacazette put Lyon well on its way to three points, while Christophe Kerbrat was sent off in the 44th for the hosts to make matters worse.
Clinton N'Jie scored just after the hour mark to extend the lead to 3-0, making Claudio Beauvue's goal 10 minutes from time for Guingamp a mere consolation.
PSG sits two points back of Lyon after Saturday's result and the capital club will take on Marseille on Sunday in a highly-anticipated clash between top- three sides.
Fekir got Lyon off the mark midway through the first half when his shot from outside the box took a big deflection off a Guingamp defender before leaving goalkeeper Jonas Lossl wrong-footed.
The netminder was picking the ball out of his net again in the 39th when Lacazette was fouled inside the box by Baissama Sankoh, allowing him to convert from the spot for his 25th league goal.
Kerbrat received his marching orders just before the halftime whistle after a poor challenge on Lyon's Jordan Ferri, while N'Jie volleyed home a free kick from Ferri in the 61st to stretch the lead.
Beauvue pulled a goal back for Guingamp after stealing the ball from Samuel Umtiti as he beat goalkeeper Anthony Lopes, who had very little to do on the afternoon.
Reims remains only three points above the relegation places after losing 3-1 at Lille, while Metz climbed off the bottom of the table with a 3-2 win over Toulouse thanks to a hat trick from Modibo Maiga.
