Leicester manager Nigel Pearson labelled referee Mike Dean "one of the most arrogant men" he has ever met after awarding a game-changing penalty against Harry Kane-inspired Tottenham.
White Hart Lane bore witness to a thrilling, end-to-end encounter on Saturday, with star turn Kane capping a wonderful week with his first Premier League hat-trick as Spurs ran out 4-3 victors.
The result may have been positive but the home side were far from comfortable winners, with Jamie Vardy and Wes Morgan cancelling out the two-goal lead Mauricio Pochettino's side had built up.
Rock-bottom Leicester were in the ascendancy at that point, only for the game to be changed as David Nugent was adjudged to have fouled Danny Rose, allowing Kane to slot home from the penalty spot.
Despite a Jeff Schlupp own goal and Nugent's strike coming after that, it was Dean's decision to award a penalty which Foxes boss Pearson felt was decisive.
"Unfortunately again, another dubious decision," he told Sky Sports. "The arrogance of the man at times is frightening.
"I just find it difficult to accept that we have to deal with yet another contentious decision that has not gone our way.
"I am sure Spurs will be feeling, even though they scored four goals, quite relieved in their dressing room.
"Now it is nine games and it remains a very frustrating season for us because of the level of performance, yet we're just not getting over the line with results."
Pearson was perplexed as to why Dean awarded a penalty and also the amount of time it took the referee to make the decision.
"I am led to believe nobody else's opinion was actually involved," he said. "He took that length of time to decide that two players colliding in the box is a penalty.
"I just find it bizarre - that's probably the nicest thing I can say.
"We're in a situation where there is a lot of talk about the spirit of the game, players going around referees. There has to be an element of fairness.
"I really do feel at the moment that we continue to be short-changed. I am not suggesting, of course, that it is deliberate but we can't be on the receiving end of so many poor decisions."
Asked if Pearson would seek out Dean to discuss things, he retorted: "What's the point? What is the point of talking to him? He is one of the most arrogant men I have ever met. There we are.
"I will concentrate on what I can affect and that is my players. I will try and keep my words carefully chosen this week and hopefully your microphone will be out of the way when I choose to say something different."
Pearson was still clearly angry by the time he spoke at the post-match press conference, during which he admitted he was not sure whether his comments would incur the wrath of the Football Association.
Tottenham counterpart Mauricio Pochettino, by contrast, cut a more relaxed figure after Kane inspired his side to victory before joining up with the England squad for the first time.
"I think it was a fantastic, fantastic game, a fantastic performance," the Spurs head coach said.
"I am very pleased for him, for his first hat-trick in the Premier League.
"I think Harry is (only a) part of Tottenham, but I am happy for him. We worked hard today in a difficult game, but it's true Harry is a very important player for us."
It was a positive result, if not performance, from Spurs, who had to do without Hugo Lloris from the first minute onwards after the goalkeeper collided with team-mate Kyle Walker.
The France goalkeeper left the field on a stretcher after several minutes of treatment on a gashed knee which could keep him out of their upcoming international fixtures.
"He's in hospital with the doctor and we wait for news," Pochettino said. "He got a big cut on the tendon of his knee. We hope it's nothing big."
