Newcastle United manager Steve Bruce says he is 'struggling to cope' with the presence of VAR.
Bruce bemoaned the system after his side suffered a 1-0 defeat to Sheffield United on Tuesday.
The Englishman was furious that Billy Sharp escaped a red-card for a poor challenge on Fabian Schar.
"There's a horror challenge by Billy Sharp that should be a straight red card. It's blatant," said Bruce. "They didn't check it. It's laughable the whole VAR situation and I don't think anyone enjoys it.
"I'm struggling to cope with it. Week in week out, it's ruining the game."
