Arsenal head coach Unai Emery suggests he could look to fortify his defence when the January transfer window opens.
The Gunners have been amazing this season and at present occupy fifth place on the Premier League standings, getting beat just twice.
But Emery finds himself with just just one in good shape sweeper in Laurent Koscielny in advance of facing Southampton on Sunday.
Up initially however is a home clash in the Europa League with Qarabag on Thursday.
Konstantinos Mavropanos, Rob Keeping and Shkodran Mustafi are wounded although Sokratis Papastathopoulos is suspended.
Emery claimed: “I consider if we can take just one player to enable us at sweeper, I consider it truly is a very good option.
“The transfer (window) is not straightforward. Koscielny is coming back and for the team it truly is very important he is coming back.
“Then we are going to hold out and see how Mavropanos is improving upon with his accidents, simply because he is also a sweeper who can enable us.
“Another option we can play with two, with a few, and (comprehensive-backs) Nacho Monreal and (Stephan) Lichtsteiner can play in this position.
“I prefer to use, if we can, a expert sweeper.”
