Jamie Carragher says Arsenal need more defenders if they are to challenge for the Premier League title anytime soon.
The former Liverpool defender suggests that Arsene Wenger is short of quality players at the back and must add to this department in the winter transfer window if the north Londoners are to truly challenge for silverware.
"Whether they are conceding goals or racking up clean sheets, Arsenal need another defender - probably two," Carragher wrote in his Gunners analysis for Sky Sports.
"Numbers-wise they are very low in that department, with Per Mertesacker, Laurent Koscielny, Nacho Monreal, Kieran Gibbs, Calum Chambers and the currently-injured Mathieu Debuchy the only established players.
"You can't really expect to get through a whole season with that few players and with Thomas Vermaelen going (to Barcelona) in the summer, I think they need another centre-back to come in, preferably one with pace.
"I also think they could do with a bit more speed in central midfield but strengthening at the back is key for them at the moment."
Arsenal currently sit fourth on the Premier League table with 17 points from 10 matches but their defence has conceded 11 goals during that time.
