Goalkeeper Wojciech Szczesny (hip) and striker Yaya Sanogo (hamstring) will be assessed, but forward Olivier Giroud could come back in having been ineligible for the midweek Champions League win over Borussia Dortmund, along with fit-again defender Laurent Koscielny.
Arsenal's injury list
Arsenal's injury list
1/5 Mikel Arteta (midfield)
Like Diaby, the Spaniard is closing in on a return but the Swansea match will come to soon. The club captain last played in November.
2/5 Mathieu Debuchy (defender)
Returned in the FA Cup semi-final win over Reading but has since been ruled out with injury and Wenger confirmed he remains 'unavailable'.
3/5 Alex Oxlade-Chamberlain (midfield)
Suffered a hamstring injury against Manchester United in the FA Cup and hasn't played since as it has exacerbated a groin problem. Out at least until May and facing surgery in the summer.
4/5 Aaron Ramsey (midfield)
Aaron Ramsey caught a kick on his calf during the win over Hull and was later substituted. The Welshman was rated 50/50 for the Swansea match by Wenger, but it now appears that he is a major doubt for the clash at the Emirates.
5/5 Danny Welbeck (forward)
Danny Welbeck has not played since the goalless draw with Chelsea towards the end of April after suffering a knee injury. Wenger has confirmed that the injury is 'nothing major', and that he should return to full fitness before the end of the season.
Captain Mikel Arteta (calf) if definitely out, as is Jack Wilshere, set for three months of recovery after ankle surgery, and Theo Walcott (groin). Mesut Ozil (knee), Mathieu Debuchy (ankle), goalkeeper David Ospina (thigh) and Abou Diaby (calf) are all still unavailable.
Wenger said of Wilshere today: "I think he will be back at the end of February, beginning of March, and he will focus on coming back to rehab, having a strong rehab, and then I am sure he will help us to do well until the end of the season.
"Jack always came out stronger and, when I spoke with him, the final sprint of the season is already in his mind and [he wants] to come back stronger.
"He is prepared and focused to come back and finish the season well."
