Gabriel failed to learn his lesson against Crystal Palace following Mikel Arteta's outburst last month.
The Brazilian centre-half was at fault for both goals Arsenal conceded in the first half at Selhurst Park as they found themselves 2-0 down at the break. Wilfried Zaha's penalty would secure a 3-0 win for the hosts, a damaging setback for the Gunners in their race with Tottenham to finish in the top four.
The north Londoners were all over the place defensively as Nuno Tavares replaced the injured Keiran Tierney at left-back. Jean-Philippe Mateta opened the scoring for Patrick Viera's men from a set-piece before Jordan Ayew gave Palace a two-goal cushion. And Gabriel didn't cover himself in glory for either goal.
