Arsenal legend Ray Parlour has told Unai Emery to sign a central defender in January.

The Spaniard has been light on options at the position, but Laurent Koscielny is close to returning from a long stint on the sidelines with an achilles injury.

He told Express Sport: 'I don't know. I really don't know. 'I'm sure they'll be positions he wants to.

'I'm sure they'll be positions he wants to. For me centre-half he could probably strengthen.

"But he's got [Laurent] Koscielny coming back, they've missed him, but he's a little bit older but I'm sure he's working hard to get back in the side so I think he'll assess the situation when it comes to January. He'll be lining people up anyway."
