Arsenal face another tricky Premier League test when they travel to Stamford Bridge to play against Chelsea on Saturday.
Unai Emery's side were defeated 2-0 by Manchester City on the opening day of the season while Maurizio Sarri's men beat Huddersfield comprehensively.
Both teams have undergone transformations on and off the pitch over the summer with Emery installing new ideas in Arsenal's tactical set up and Sarri applying his own philosophy at Chelsea.
Left-back Sead Kolasinac is out for eight to ten weeks with a knee injury while Ainsley Maitland-Niles has suffered a fracture in his left leg and will be out for six to eight weeks.
Long-term absentee Laurent Koscielny is aiming to return to training at the end of the year.
Arsenal have no suspensions for this game.
Possible Arsenal starting line-up
Emery could hand Lucas Torreira his first full Premier League start in defensive midfield, while Nacho Monreal or Stephan Lichtsteiner will start at left-back.
Alexandre Lacazette, Pierre-Emerick Aubameyang and Mesut Ozil will continue in attack with Henrikh Mkhitaryan playing in an inside right role.
Chelsea team news
Chelsea have only one injury concern and that is Cesc Fabregas, who is a major doubt after suffering a knee injury against Arsenal in pre-season.
Fabregas is unlikely to be passed fit against his former club after struggling through the 2-0 Community Shield defeat to Man City, while he also missed the Blues' Premier League opener.

Kick-off is 5:30pm BST (12:30am ET) on Saturday August 18, and the game will be shown on BT Sport in the United Kingdom. It will be shown on NBC in the United States, and on various channels around the world.
