Centre-back Laurent Koscielny is also in contention to start against Everton after limping off with cramp at Vicarage Road last weekend, though forward Danny Welbeck remains out and a couple of others are facing longer layoffs
"Alexis, Koscielny and Ramsey will be alright," Wenger told reporters. "Welbeck is out - he has a groin problem. I think it will be two to three weeks before he is back. He will not be back before the international break.
"Mustafi will not be back before the break, and Ospina as well. Ospina is not very bad, he has a grade one [groin problem] so it's just a couple of weeks.
"Mustafi is a bit worse than Ospina. Calum Chambers as well will be back after the break, and everybody else is alright."
