Arsenal's need for a new defender is more pressing then many think.
Arsenal go into this evening's game with QPR once again short of defensive options. The Gunners defensive transfer plans in the summer were simply flawed. They sold Thomas Vermaelen, allowed Carl Jenkinson out on loan and Bacary Sagna left on a free transfer.
To replace them only Calum Chambers and Mathieu Debuchy arrived, neither a proven central defender.
Wenger has made it clear that this was a mistake. In the winter Arsenal are set to go hunting for a new central defender, especially considering the likes of Debuchy and Nacho Monreal have had to fill the position this season.
But should Arsenal actually bring in two new central defenders?
A third is needed regardless and here is why.
Mertesacker is no spring-chicken, he never was. His intelligence has often got him out of sticky situations caused by his lack of physical attributes.
Koscielny is the future leader of the back-line at Arsenal, but his current injury problem cannot be underestimated.
What the French defender has at the moment is chronic tendinitis in his calf. The fact is this problem could be an issue for the rest of his career and sporadic absences are now going to become commonplace.
The fact is Arsenal need to bring in two top class central defenders if they are going to challenge for the title once again, as well as a quality holding midfielder.
Until then they will continue to be the Premier League also-rans.
