Arsene Wenger expects Alexis Sanchez to be fit to face Manchester United despite being forced out of Wednesday night's rout of Huddersfield.
The Arsenal ace was on the scoresheet on the 5-0 drubbing but was replaced late on due to a hamstring problem.
Club-record signing Alexandre Lacazette will "certainly be out" of the contest at the Emirates after being substituted at half-time with a groin injury.
However, Wenger is confident Sanchez will recover in time for Saturday's crunch clash against the Red Devils.
"Sanchez had a little hamstring problem - that's why I took him off but I think he will be alright," he said.
"Look, we have offensive weapons, you know. We have Danny Welbeck, we have Giroud, we have Jack Wilshere who all came on. They are all offensive players.
"I will see what I do for Saturday but ideally you wanted him (Lacazette) there."
