Southampton are reportedly upset at the Football Association's decision to rescind Arsenal midfielder Mohamed Elneny's red card.
The former Basel player was dismissed by referee Andre Marriner on Sunday, as his side beat Southampton 3-2 at the Emirates Stadium.
Elneny was involved in a heated situation with Saints full-back Cedric Soares in the closing minutes of the game, and was originally punished with a three-match ban.
The sanction was overturned on Tuesday, and Sky Sports News claims that Southampton are angered by the decision.
The report also suggests that the club are upset at the lack of disciplinary action against Gunners midfielder Jack Wilshere, who received a yellow card for pulling the shirt of Jack Stephens.
Stephens was sent off for his reaction to the foul, meaning that he will serve a three-match-ban for violent conduct.
