By his own admission Sagna has struggled at times since he returned from a long-term injury.
"I’m going to be honest with myself - [I’ve not been] at my best," he told Arsenal Player.
"I’m not very happy with myself, but it’s football. It’s a part where I need to get better. I’ve been working since last summer but I need to work more because I’ve been out a long time.
"I didn’t really have a pre-season but at a high level you don’t have time to breathe. You have a game every three days and have to keep coming. I’m looking forward to coming back to my best."
