The Gunners have now seen four men red-carded in 2022, and since Arteta’s first game in charge of Arsenal on Boxing Day in 2019, they have received 15 red cards in all competitions, seven more than any other Premier League side.
Arteta was perplexed at how the Martinelli was sent off for separate yellow cards in the same phase of play against wolves on Thursday.
Late in the second half, Martinelli first infringed upon a throw-in, with advantage being played, and moments later hacked down Chiquinho. Both offences were deemed worthy of yellow cards by the match officials.
