Minutes earlier, Souquet's Montpellier teammate Andy Delort had hammered a penalty against the post. Lyon's chances of coming back into the game were hampered when new signing Youssouf Kone was sent off in the 51st after pushing his head into Delort as they squared up.
Jason Denayer could have leveled for Lyon, but sent a header narrowly wide of the post at a corner. Lyon's defeat keeps Rennes top of the league as the only team to win all three games so far, three points ahead of Lyon and defending champion Paris Saint-Germain. Nice could join Rennes at the top if it beats Marseille on Wednesday.
