Michael Owen believes an Arsenal star should be calling his team-mate out in the dressing room after the Gunners were held to a 2-2 draw by Crystal Palace on Wednesday.
The Gunners needed a victory to keep their fading title hopes alive while also cementing second place, but were pegged back twice by their London rivals.
Palace's second equaliser came after William Saliba gave the ball away cheaply to Jean-Philippe Mateta, who turned away from Martin Odegaard before delicately chipping the ball over David Raya and into the net.
