Sheffield United manager Chris Wilder said VAR is thought of as a "four-letter world" in England due to its implementation in the Premier League this season.
Wilder's United side lost their first away match of the season at the Etihad, winding up on the wrong end of a 2-0 scoreline against Manchester City in a game that once again saw VAR take centre stage for all the wrong reasons.
Asked about the City fans joining in with the visitors in expressing strong opposition to VAR, Wilder said he was not surprised.
"Up and down the country, all the people at Norwich, a four-letter word about VAR, these are proper football people," Wilder said.
