Former Liverpool defender Jamie Carragher has claimed that Arsenal need to sign two defenders in January's transfer window.
The Gunners have found themselves conceding goals in recent games following injuries to defensive players, as well as the departure of Thomas Vermaelen.
Carragher told Sky Sports News: "Arsenal need another defender – probably two. 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 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."
Arsene Wenger's charges were three goals up against Anderlecht in Tuesday's Champions League clash at the Emirates, but the Belgians secured a point after pulling the game back to 3-3 in the last half-hour.
