Arsenal are set to appeal Kieran Gibbs red card, and the red card decision itself.
With referee Andre Marriner making a complete bollix of the situation, and sending off Gibbs instead of Alex Oxlade-Chamberlain, it’s likely the left-back will be available for the game on Tuesday.
However, Arsenal are also to appeal on the basis that Oxlade-Chamberlain’s handball did not prevent a goalscoring opportunity and therefore the red card itself should be rescinded.
We have yet to discover from the officials on what basis they made their decision. Marriner seemed content for Arsenal to take a goal kick, but then changed his mind to award both a penalty and a red card.
With no monitor on the sideline for the fourth official, the options are that he either got guidance from somebody who did have video in front of them, or he was swayed by protestations from Chelsea players and management.
Neither option covers the referee in glory and a full explanation of his decision should be demanded.
