Arsenal boss Arsene Wenger has confirmed that a number of key players could be back for tomorrow's North London derby against Tottenham Hotspur.
The Gunners will open a six-point gap from their rivals if they take all three points.
"We have still some uncertainties at the moment because Kieran Gibbs has been touched on his shoulder and I don't know how will respond to that," Wenger explained.
"After, the players who did not travel [in the Champions League] like [Santi] Cazorla, [Nacho] Monreal, [Theo] Walcott - there is still some uncertainty today. The closest to coming back looks to be Walcott. We will have a test with him.
"Hector [Bellerin] has a test.
"I left him behind [in midweek] because I was cautious with him. We could have basically forced the issue, he could have played maybe in Bulgaria but he should be alright [for Sunday].
"He [Nacho Monreal] has tests today and tomorrow and then we will decide. [Santi Cazorla] is similar, he has not practised yet - he will try to go out today and we will see where we go from there. He is a doubt, yes."
