Norwich manager Glenn Roeder was left fuming with referee Andy D'Urso after Bristol City claimed a late 2-1 win at Ashton Gate.
Roeder believes that the free-kick that led to substitute Steve Brooker's winner came after a handball was committed by a Bristol City player, leading him to confront D'Urso after the final whistle.
And the Canaries boss remains furious about the decision.
"I've never walked on to the pitch and remonstrated with a referee like that before," said Roeder. "It's not my style - and it was an indication of how angry I was.
"The referee has made a big mistake in judging that the wrong hand touched the ball. Even the fourth official said it was clearly a Bristol player but added that there was nothing that he could do about it.
"With luck like that, Bristol are certainties to reach the Premier League, yet we outplayed them from start to finish.
"The problem is that referees are not accountable for such errors. My players have given everything, produced some excellent football and have nothing to show for it."
Robins boss Gary Johnson was simply delighted to see his side return to the top of the Championship after the victory - and he reserved special praise for Brooker.
"It was a fairytale finish, because Steve has been through an 18-month battle against injury and only just returned from his loan at Cheltenham," he said.
"Everyone at the club knows how hard he has worked after two knee operations - and this was the perfect reward for him.
"The game could have gone either way, but we kept going to the very end and now sit top of the Championship with just five games left.
"We are the team everyone has to catch, and it was a terrific boost to clinch a victory that ends our run of five games without a win."
