Midfielder Lucas Torreira has travelled with Arsenal for their Europa League quarter-final second leg at Napoli.
The Uruguay international has been struggling with a groin injury and was substituted at half-time in the 1-0 win at Watford on Monday.
Defender Sokratis Papastathopoulos may also return for the Gunners after being suspended at Watford.
Napoli are likely to be without midfielder Amadou Diawara and Spain defender Raul Albiol.
Gunners going for goals
Arsenal head to the Stadio San Paolo holding a 2-0 advantage from the first leg at Emirates Stadium.
But manager Unai Emery says the Gunners will not play a containment game and will instead press for an away goal that would leave Napoli needing to score four times.
“We know 90 minutes here can be long, but we want to play this match not thinking about the first leg,” Emery said.
“We want to play thinking to win, thinking to score, thinking to push, thinking to stop them.
“Thinking also tactically to be together and thinking when we have the space to attack the space.
“They have a lot of players with a big quality to push against us and give us a lot of problems but we also have the players to fight against them with our quality.”
‘Courage, intelligence and heart’
Manager Carlo Ancelotti says Napoli will need “a lot of heart” if they are to progress after losing in London.
The Serie A club have not won a European trophy since Diego Maradona inspired them to Uefa Cup victory in 1989.
“I saw only a little courage in the early stages of the first game,” Ancelotti said.
“Intelligence, I saw in both halves of the match. Heart is something we will put in tomorrow. We also need a significant dose of intensity.
“We must seize this opportunity, we need a positive mental attitude and, I repeat, a lot of heart. Napoli will put in a great display tomorrow – I believe we can do it.”
