Mikel Arteta has defended Bernd Leno after the Arsenal goalkeeper was sent off in Tuesday's loss to Wolves.
Both Leno and David Luiz earned straight red cards on Tuesday as nine-man Arsenal were undone in a 2-1 defeat.
Luiz was dismissed just before half-time with Arsenal leading 1-0, as the Brazilian clipped Willian Jose in the box to earn his marching orders while handing Wolves a penalty.
