The 27 year old was stripped of the captaincy following his angry confrontation with Gunners fans in a game against Crystal Palace last month.
The midfielder has not featured in Arsenal's last four games but boss Emery feels he is now ready to return.
"We will decide on Friday," said Emery.
"He is coming back better in his mind, his mindset is better to help us and to be closer to playing when we need him."
Emery added: "I spoke to him this morning and we had a very good conversation. He trained very well before the international break and he trained very well this morning.
"My objective is going to be his comeback to help us and convince every supporter of his commitment with us and his performances will be better and they will be proud of him in the short or long future with us."
