Ainsley Maitland-Niles has returned to full-scale training at Arsenal.
The midfielder has recovered from a fracture to his left suffered on the opening day of the season against Manchester City.
Petr Cech returned to training earlier than expected this week after suffering a hamstring injury against Watford. Arsenal have now confirmed the goalkeeper could be in contention to return against Leicester City and will assess him over the next week.
Mesut Ozil is also now training. He sat out of his side's 5-1 victory over Fulham before the international break, with Unai Emery later explaining his player had suffered a back spasm in the lead up to the game.
