Following the game, manager Arsene Wenger revealed that Coquelin had suffered an injury to his knee and expressed his fear that the Frenchman could be out of action for an extended spell.
Wenger said: "Coquelin has a knee injury in the same place he suffered one against West Brom last year.
"We don't know if the damage is as big. We have to wait for 48 hours, but he left the stadium in a brace, so that's the one negative. I'm a bit worried for that."
Arsenal are hoping to learn more on the Coquelin problem on Monday morning.
