Arsenal team news: Forward Alexis Sanchez (hamstring) is doubtful for Sunday's Barclays Premier League clash against Aston Villa.
Alexis Sanchez: A doubt for Arsenal
However, new signing Gabriel Paulista could make the squad after joining from Villarreal.
England striker Danny Welbeck (thigh) is close to a return, but may not be risked, while midfielder Alex Oxlade-Chamberlain (groin) is also expected to come into contention ahead of the north-London derby at Tottenham next weekend.
Midfielders Jack Wilshere (ankle), Mikel Arteta (ankle) and Abou Diaby (calf) are all still out, as is full-back Mathieu Debuchy (shoulder).
Meanwhile, Scott Sinclair is likely to go straight into Aston Villa's squad for Sunday's trip to Arsenal after joining on loan from Manchester City.
The winger will train with the side on Saturday before boss Paul Lambert makes a final decision on his inclusion.
Forward Gabriel Agbonlahor has recovered from a hamstring injury while Joe Cole (also hamstring) is training but not yet fit. Defenders Ron Vlaar (knee) and Philippe Senderos (calf) both remain out.
