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.
Arsenal injuries
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.
