Arsenal boss Mikel Arteta has taken a swipe at Premier League officiating, accusing the league of inconsistency when it comes to applying the rules.
The Gunners have been shown five red cards this season, the joint-most of any team in the top flight, level with Ipswich Town.
Several of those dismissals sparked controversy, with Declan Rice and Leandro Trossard both sent off for delaying the restart early in the campaign.
Arteta believes his players were harshly punished at the start of the season, only for the interpretation of the rules to change as the campaign went on.
