Arsenal will be without suspended midfielder Lucas Torreira for Sunday's Premier League clash with Manchester United.
The Uruguay international was sent off in last weekend's draw at Tottenham and is banned for the next three league games.
Alexandre Lacazette is available having missed the Europa League defeat in Rennes through suspension, with long-term injury absentees Danny Welbeck (ankle), Rob Holding and Hector Bellerin (both knee) still missing.
Meanwhile, Anthony Martial will return for Manchester United, with Nemanja Matic and Ander Herrera also on the brink of returning.
United were without 10 first-team players for Wednesday's 3-1 Champions League win at Paris St Germain. Paul Pogba is available after serving a European suspension and Martial is back from a groin injury.
Ole Gunnar Solskjaer revealed that Matic (groin) and Herrera (hamstring) could return, but Alexis Sanchez, Jesse Lingard, Juan Mata, Phil Jones, Antonio Valencia and Matteo Darmian remain unavailable.
