Premier League managers Ange Postecoglou and Pep Guardiola believe refereeing mistakes will always happen in football, despite the introduction of the Video Assistant Referee (VAR). The technology has been in the spotlight following Liverpool's 2-1 defeat against Tottenham, where Luis Diaz had a goal wrongly disallowed. Spurs manager Postecoglou believes referees make errors just like players and coaches do, while Manchester City manager Pep Guardiola hopes the system can be improved following the latest controversy.
