Eberechi Eze will be in the Arsenal for the first leg of the Champions League semi-final tie against Atletico Madrid.
The Gunners travel to the Metropolitano Stadium on Wednesday night to take on Diego Simeone's side, who they beat 4-0 in the league phase of the competition in October.
Eze had been a doubt for the match after he was forced off against Newcastle over the weekend but he took part in Arsenal's open training session on Tuesday.
However, Mikel Arteta has confirmed that Eze is fit and available, though there is a chance the Spaniard could still be cautious with his fitness.
Gabriel Martinelli has scored six goals in the Champions League this season and is pushing to start on the left wing, offering more pace on the counter-attack.
Kai Havertz is out with the muscular injury he picked up against Newcastle, though that injury is not believed to be a serious one.
With the German out, Viktor Gyokeres is likely to get the nod to lead the line over Gabriel Jesus.

Bukayo Saka could make his first start in more than a month having recovered from an Achilles injury. The winger looked sharp in a brief cameo off the bench last time out and Arteta might decide to restore him to the starting lineup for such a big occasion.
Jurrien Timber has not returned to training and will be absent once again. Arteta admitted at his press conference that he does not know when the Dutchman will return.
“He’s doing some stuff on the pitch at the moment,” Arteta said.
“But we need to get the gears up and be able to do more things before he can compete with us.”
Although Riccardo Calafiori is available again, Arteta could opt for the more defensive full-back combination of Piero Hincapie and Cristhian Mosquera.
Predicted Arsenal XI: Raya; Mosquera, Saliba, Gabriel, Hincapie; Zubimendi, Rice; Saka, Odegaard, Martinelli; Gyokeres
Injured: Timber, Merino, Havertz
