Arsene Wenger has confirmed that Laurent Koscielny is fit to face PSG after his facial injury turned out not to be as bad as feared.
Speaking to the media at his press conference, which was delayed for almost an hour after Wenger and Hector Bellerin were stuck in traffic, the manager confirmed that Kos, who was in training with the squad on Monday, is fit to play.
Arsenal do not have any other injury problems ahead of the game. Aaron Ramsey returned to training on Monday but was working away from the main group as he looks to regain his fitness after being out since he did his hamstring in the first game of the season.
PSG have their own problems ahead of the game, and you can find out more about those in our comprehensive audio review with French football expert, Lana Dawood.
