In some good news on the injury front for the Gunners, defender Laurent Koscielny and midfielders Mikel Arteta and Mathieu Flamini could make their comebacks against Watford on Saturday.

Koscielny hasn't featured since injuring his hamstring against Olympiakos while Arteta and Flamini have been missing since the victory against Leicester City on September 26.

Manager Arsene Wenger said: "Koscielny has a slight chance to be back on Saturday. He has a definite test on Thursday.

"Arteta and Flamini are back in full training. We need to see how they are and how confident they are, but we can't rule it out."
