Mikel Arteta apologised to Arsenal fans after he lamented their lack of "composure" in the 3-0 defeat at Crystal Palace.
The Gunners boss watched on as his side were second best at Selhurst Park with Tottenham now occupying fourth spot. Arsenal knew they had to respond against the Eagles after their neighbours comfortably saw off Newcastle United on Sunday. Arteta's side were 2-0 down at half-time and failed to mount a second-half response.
Wilfried Zaha then made it 3-0 as Arsenal's Champions League hopes suffered a major setback. The Gunners are aiming to end a lengthy wait for a seat at Europe's top table having slipped out of the top four picture until this season but Arteta bemoaned the nature of their performance at Palace.
