Arsenal boss Arsene Wenger has revealed that he is hopeful of having Theo Walcott available for Sunday's London derby with Tottenham Hotspur in the Premier League.

The England international was expected to miss out against Spurs due to an ongoing hamstring problem, but Wenger has hinted that the forward has a chance of being fit for the key league fixture.

However, Spanish midfielder Santi Cazorla, who has an Achilles problem, "is a doubt" having not yet returned to training for the Gunners.

"Walcott the closest, definitive test today. Nacho has tests today and tomorrow, then we will decide. Cazorla has not practised yet. We will try to go out today and go from there. He is a doubt," Wenger told reporters.

Wenger also claimed that stand-in left-back Kieran Gibbs is a doubt for the match after picking up a shoulder problem during Tuesday's 3-2 win over Ludogorets Razgrad in the Champions League.
