Arsenal have been forced into a late change for their Premier League clash with West Ham as Kieran Tierney is replaced by Sead Kolasinac.
The Scot is understood to have a tight hip so will not be risked for the game.
"Kieran Tierney's tight hip means Sead Kolasinac starts. Joe Willock takes Seo's place on the bench." Arsenal tweeted.
While Tierney's injury will serve as a major blow, Arsenal received a boost in regard to player availability ahead of the game with David Luiz declared fit.
The Brazilian missed the opening day of the season win at Fulham due to a neck spasm but has made the bench for tonight's game against the Hammers.
Tonight [September 19] will be Arsenal's first match since the confirmation that Aubameyang signed a new three-year deal to stay with the club.
Club captain, especially under Arteta, the 31-year-old has gone to another level in an Arsenal shirt. While his goals remain a guarantee [72 in 111 games], his work out of possession and leadership qualities have become invaluable to the side. Ahead of the clash with West Ham, the manager spoke about just how important it was to keep the Gunners' main man.
"Obviously I knew what was coming so I was a little bit more relaxed," he said in his pre-match press conference.
"I am really pleased to have convinced Auba to stay at our club, as well in the terms that we've done. With the passion and determination that him and the people around him show to stay at our club, how happy they are with what we have achieved.
"As well, really pleased to see the reaction of everybody. First of all here at Colney at our club and as well our fans, to keeping him.
"It's a joy to work with him. I think we have a very transparent relationship, we were very clear with each other with what we were trying to do.
"How big a part of my plans for now and for the future. The way he trains, the way he behaves himself and the way he performs is exactly what I want. So, I want him to do that again, consistently in the next few years."
