Stoke boss Tony Pulis bemoaned the display of referee Lee Probert in their 2-1 Carling Cup defeat to Liverpool.
Probert disallowed a John Walters goal for a foul on Reds keeper Pepe Reina and did not award a penalty when Peter Crouch went over in the box late on.
"It's got to be even stevens and tonight we don't think it was even stevens in terms of some of the decisions," Pulis told BBC Sport.
"You can't have some rules in one box and different rules in the other box."
Walters' header was ruled out for a push by Ryan Shawcross on Reina when the score was 0-0.
Stoke took the lead soon afterwards through Kenwyne Jones but were sunk by two second-half strikes from Liverpool striker Luis Suarez, with the winner coming four minutes from full-time.
Pulis was particularly incensed by the disallowed goal and suggested Probert had given his team a rough deal in the past.
"We have had Lee a few times now and had three goals disallowed," he added.
"One at Aston Villa a couple of years ago, a great goal by Tuncay against Everton last year, and tonight it was a perfectly good goal.
"You will have to ask Lee why [he disallowed it] because we don't know why."
Pulis was also angered that Liverpool defender Jamie Carragher was not shown a red card for a first-half foul on Matthew Etherington.
"Jamie Carragher doesn't play the ball at all but if that was one of our players we would expect them to be sent off," he said.
Reds boss Kenny Dalglish preferred to dwell on the performance of Suarez, whose first goal was a sensational curling effort from the edge of the box after he had nutmegged Stoke's Ryan Shotton.
"I don't think he's ever going to score with a tap-in," he said. "He has megged the guy and then bent it in. We know the quality he has got and not much surprises you.
"The attitude and desire pleased me. If you don't match that here you are going to struggle.
"Every win's important but I think the most important thing was that we hung on in there."
