Stoke manager Tony Pulis felt his side had been "kicked in the teeth" by poor refereeing decisions during their 1-0 defeat at Norwich.
Bradley Johnson's headed goal proved enough to secure the Canaries a second successive Barclays Premier League home win. Pulis, though, disputed the award of the initial free-kick for a foul by full-back Andy Wilkinson on Robert Snodgrass out on the far touchline, and also referee Andre Marriner ruling Charlie Adam had dived earlier in the first half.
"The goal was a disappointment. I have been in to see the referee to have a quick chat," said Pulis. I thought it certainly was not a free-kick, and the disappointing thing is when the lad falls, Andre and the linesman are so close to it."
Pulis added: "He has booked Charlie in the first half for diving - I have just had a look at that and [Javier] Garrido pushes him in the back, so that is a double kick in the teeth when he gets both those decisions wrong and even worse when they score from it."
Diving has become a contentious issue in the English game, and Pulis believed retrospective punishment is the way forward.
He added: "Referees give the decisions they see on the day, and he has seen it differently to what we have. When he sees it again on the telly tonight, he will have a different opinion.
"I think the [diving] situation should be taken completely out of the hands of the referees and it should be retrospective on a Monday, there should be a panel which sits to decide whether a player has dived or not, that eases the pressure on referees and they only make that decision if they are 110% certain someone has cheated."
Norwich manager Chris Hughton defended Snodgrass against any accusations of unsportsmanlike conduct.
He said: "I have not seen it since, but I have heard the comments. If anything is labelled at Robert Snodgrass, then you have got to say the same about Charlie Adam, who went down.
"If you are looking at incidents in the game, there are so many and you are always going to pick out a few, but it is a tough physical game and you have to be able to deal with it."
