Leeds boss Steve Evans claimed Premier League referee Anthony Taylor should be demoted to under-nines football following his controversial decision in United's 2-0 defeat to Sheffield Wednesday at Hillsborough.
The visitors were trailing by two goals but looked to have given themselves a chance of snatching something from the Sky Bet Championship game when Liam Cooper turned the ball home following substitute Alex Mowatt's 78th-minute free-kick.
However, Taylor ruled it out despite blowing for Mowatt's free-kick to be taken, as he deemed Wednesday had not completed a substitution - Fernando Forestieri had not left the pitch - and after consulting his linesman ordered the set-piece to be retaken.
Evans saw the 'goal' but after nipping straight down the tunnel to the toilet, returned to see it chalked off and was left furious.
"I've been into see Anthony and he said by law he's got it right because it should be disallowed," said Evans after the game.
"I've seen many times where the referee stops it for a substitution, someone's taking far too long and he restarts play, but I've never seen somebody going back to restart play again, ever.
"He's a Premier League referee who's stepped down to take a big derby - he should be with the under-nines on the park pitches on Monday.
"You cannot make a mistake of that magnitude in a game which means so much to both sets of supporters."
Wednesday manager Carlos Carvalhal was quick to defend the decision.
"To me it's very clear. The fourth referee showed a strong personality," Carvalhal said.
"My view is very clear that he must cancel that goal because the game has stopped at that moment to do the substitution."
