Steve Bruce accused Gary Cahill of taking a tumble "like something out of Swan Lake'' and claimed he should have been sent off as Hull went down 2-0 to Chelsea.
Jose Mourinho's men edged their card-laden clash with the Tigers on Saturday as efforts from Eden Hazard and Diego Costa got them back to winning ways in the league. However, the 2-0 triumph was overshadowed by a number of controversial decisions, with referee Chris Foy dishing out seven yellow cards and a second-half red to Tom Huddlestone at Stamford Bridge.
Bruce had no arguments with the sending off, but was infuriated Cahill had not gone before that after going down in the box when Chelsea only held a one-goal advantage.
The Hull boss, as well as his players, had expected Foy to hand the England defender a second booking, only to be incensed when the referee pointed for a goal-kick.
"I've just been asked if Cahill should have gone and the simple answer is yes, especially given the referee has already booked two people for simulation or diving,'' Bruce said. "Listen, if it is Oscar, Hazard or Willian, they are running at that pace that the smallest connection can bring them over. There is no question about that.
"This is England's centre-half, by the way. For me, it could have been a red card in his first challenge on (Sone) Aluko. That was reckless and dangerous.
"So when you come, you expect the referee to do their job. It is difficult enough to come here and, consequently, Tom Huddlestone, who is the most laid back person, is frustrated with the decisions against him and produced a horror challenge which deserves a red card. But when you come to places like this, then you need them to make the right call.
"When you see it back and look at the replays, there's no justification for it because we all know what he tried to do: he has tried to win the penalty by taking off thinking (David) Meyler was going to challenge him.
"We need to stop this horrible simulation which, unfortunately, has crept in. The referees have got a hard job but that wasn't a hard decision. Not from 12 yards, not from where I was.''
Costa and Willian were both booked for simulation at Stamford Bridge, where Bruce conceded the fact Cahill was a home-grown centre-back perhaps swayed the referee it was not a dive.
That, he says, should not be the case, especially given the tumble is "like something out of Swan Lake -- it's that blatant''.
"If I say what I really, genuinely want to say, then I'll be hauled up in front of the Premier League again and I'm going to have to pay the 10 grand or whatever it was,'' said Bruce, also aggrieved by what he felt was a foul in the build-up to Hazard's opener.
"I think I paid £20-odd (thousand) last year so, before Christmas, I will make sure I button my lips and say p--- all about it and keep my money in my pocket.''
