Southampton are bottom of the Premier League while Villa are 11th
Aston Villa have been fined £20,000 by the Football Association for their players' reaction to Southampton's disallowed goal on Saturday.
James Ward-Prowse's 65th-minute strike was eventually overturned by the Video Assistant Referee for a foul in the build-up.
Referee Michael Salisbury was surrounded by Villa players and subsequently booked Douglas Luiz.
Ollie Watkins scored 12 minutes later to give Villa a 1-0 win at St Mary's.
Villa admitted the charge and accepted the standard penalty from the FA for a breach of rule E20 which states that players "failed to conduct themselves in an orderly manner".
