Arsenal boss Mikel Arteta has criticised former captain Granit Xhaka for getting sent off as the Gunners crashed to a 1-0 defeat against Burnley at the Emirates on Sunday.
The home side had all the possession and chances until Xhaka was shown a red for grabbing the neck of Ashley Westwood in the second half, with the one-man advantage allowing the Clarets to gain impetus in the contest.
Pierre-Emerick Aubameyang scored at the wrong end shortly after to secure victory for Burnley, with the club captain now not having scored from open play for his own since the opening day of the Premier League season in September.
