Elsewhere, Monaco playmaker Joao Moutinho came off the bench to salvage a 2-2 draw with Caen by converting a cross from Yannick Ferreira Carrasco in the 75th minute. Monaco lost ground in the race for a Champions League spot, trailing PSG by 10 points.
"We lost two points even though we dominated," Ferreira Carrasco said. "Our goal is a top-three finish. There's still a long way to go. We are not saying that we're going through a crisis but we need points."
