Manager Ralph Hasenhuttl said video refereeing was "destroying the game" as he reacted to a controversial penalty decision during Southampton's defeat by Wolves.
Danny Ings scored in the 25th minute to give Saints a 1-0 lead, and Hasenhuttl's men comfortably held the advantage until Wolves were awarded a second-half penalty when Ryan Bertrand blocked Nelson Semedo's attempted cross with his arm.
The point of contention was whether the left-back's arm was in an unnatural position. The VAR team, led by official Martin Atkinson, saw no need for the on-field referee to reconsider his initial decision to award the kick.
