The France international played in the under-21s against Reading earlier this week and is ready to step-up his rehabilitation.
The 29 year old told Arsenal Player: "When you have such a big injury once, you take it, but twice is hard. In my mind I was a bit sad, but the next day I was ready for the challenge, which was to come back stronger and I am in a good way today.
"I spent some time in the rehab centre, then I came back and worked really hard with the fitness coach and the physios to be ready to play - and finally I have.
"I don't have any target - my only aim is to be ready and bring what I can to my team, to give 100%, like always."
