Arsenal boss Arsene Wenger has revealed that Laurent Koscielny and Theo Walcott could be fit for his side's Premier League clash against Sunderland.

Walcott has been sidelined since the Gunners' defeat to Sheffield Wednesday in the Capital One Cup, while the Frenchman suffered an injury in his side's draw against Norwich City last week.

However, Wenger has disclosed that both players could be included in the squad for the club's match against the Black Cats along with Kieran Gibbs.

He told the club's official website: "We will make a decision on Saturday on Koscielny and Walcott - they could both make the squad. Kieran Gibbs is available again for the weekend."

Wenger has also revealed that he is unsure how long Santi Cazorla and Alexis Sanchez will be sidelined with their respective injuries.
