Arsenal boss Arsene Wenger says his players will not underestimate Anderlecht when the two teams face on Tuesday night.
The Gunners needed two late goals in the dying minutes of the game to win the game in Belgium and the Frenchman is aware of the strength of Besnik Hasi's side.
"We are at home and we have an opportunity to win the game," Wenger said on Monday.
"We are on a good run and we want to take advantage of that.
"We respect Anderlecht because they gave us a tough game.
"We had a little bit of a miraculous win because we needed to go till the last minute. We have been warned. We have learned a lot from the first game and we want to win at the Emirates now."
Asked about the fitness level of the injured players, Wenger said: "The squad is exactly the same that played against Burnley.
"He [Jack Wilshere] has been sick and he will not be involved tomorrow. Yes, [he should be fit for the weekend].
"We had Olivier Giroud, Theo Walcott, Mathieu Debuchy and Mesut Ozil injured but they are slowly all getting better.
"Theo is the first to come back but I believe we are at the end of the tunnel.
"I am happy if Walcott goes with England because he needs games.
"He is now in a period where he needs hard training and games so I would be happy with that."
