Arsenal boss Unai Emery defended Shkodran Mustafi after their shock defeat to Crystal Palace.

Emery was asked about Mustafi's performance, after the defender was at fault for Palace's second goal.

He said, "We can speak about players individually, but sometimes they can play very well, sometimes cannot play well. But I prefer to speak about the consistency in the season. I think we are, every player, helping and every player is playing with a big performance and today also, when you can defend against a player like Benteke or Zaha, you can suffer more than maybe in other situations.

"But if today we were better in the set pieces, maybe we could have won this match."

Asked if he thinks Mustafi has been consistent this season, Emery added: "In all the season I think he is being consistent. We speak about every match."
