Arsenal boss Unai Emery was delighted for captain Laurent Koscielny after his winning comeback for last night's Europa League victory over Qarabag.

Koscielny has been missing since suffering an Achilles injury in May.

Emery said, "When a player comes back like Koscielny, after a big injury… a very big injury, it can give the player different moments. I think for Koscielny it's good that he's recovered and I also think he recovered in a good time from his big injury.

"When he comes back like today with us, every supporter of Arsenal is happy, and also the player. Then this process with him is to take confidence again, take rhythm for playing matches like today.

"We are going to continue this process maybe on Sunday. I want to wait tomorrow and Saturday for how he will feel after this match, for if he will play or not on Sunday."
