Sheffield United manager Chris Wilder's unhappy relationship with VAR reached another low on Monday as his side lost 1-0 at Aston Villa having played most of the match without captain John Egan following his early dismissal.

Wilder was left confused after the 10-cap Republic of Ireland international was shown a red card in the 12th minute for an apparent tug on the shirt of Villa striker Ollie Watkins who was running clear. 

Referee Graham Scott was some distance from the incident but decided, even though his assistant did not flag for a foul, that the challenge had denied a scoring opportunity and sent Egan for an early shower. 

Wilder, who was late for his news conference after trying to quiz the referee on the incident, said it should have been checked by VAR and Scott should have taken another look for himself on the pitchside monitor. 

"I just don't understand why that decision was first made as a straight red and no dialogue with the assistant referee. His actions are a giveaway," Wilder said. 

"It's difficult to be completely 100% certain from Graham's position behind both players that they were not grabbing each other. My big argument was that the assistant referee was 10 yards away and had the clearest view and he made a decision not to wave his flag for a foul. 

"I am completely confused as a professional player and manager for the last 35 years. I am at my most confused about the decisions being made. I am even more confused tonight." 

Wilder's team were denied a clear goal against Villa in June when goal-line technology failed in the first game after the Premier League restart from the COVID-19 shutdown. 

Last season Sheffield United also had a goal disallowed by VAR at Tottenham Hotspur when John Lundstram's toe was ruled to be offside after a lengthy decision-making process. 

To make matters worse on Monday, Wilder felt that Villa's Matt Targett should have been sent off when fouling Chris Basham to concede a first-half penalty which Lundstram then had well saved by goalkeeper Emiliano Martinez. 

"Bash does great and puts himself between the ball and the man, there's no way in a million years he can wrap his foot round the ball and make the tackle. He impedes our player, a chance denied and it's a red card," Wilder said. 

"It can't be double jeopardy, it's a red card, he's stopped a goalscoring chance. "Even if he misses the penalty it's still 10 vs 10."
