Arsenal boss Unai Emery has confirmed he may buy a new centre-half in January.

The Gunners are without a host of centre-backs and look like heading to Southampton on Sunday with only one recognised fit defender in recently returned Laurent Koscielny.

"I think if we can take one player to help us at centre-back, I think it's a good option," Emery said.

"The transfer (window) is not easy...Koscielny is coming back and for the team it's very important he is coming back.

"Then we are going to wait and see how Mavropanos is improving with his injuries, because he is also a centre-back who can help us. Another option we can play with two, with three, Nacho Monreal and Lichtsteiner can play in this position. I prefer to use, if we can, a specialist centre-back"
