Stoke manager Tony Pulis wants former players to rule on diving after accusing Norwich City's Robert Snodgrass The Stoke City manager was left nursing another perceived grievance on Saturday after Norwich's Robert Snodgrass collapsed to the turf following a challenge by Andy Wilkinson. Snodgrass duly delivered the free kick that Bradley Johnson headed in for Norwich's winner. After Pulis had paid a visit to the referee's room after the match, match official Andre Marriner agreed that he would look at the decision again, although that was scant consolation for Pulis, who has called for former players, rather than referees, to sit on panels and retrospectively judge whether or not a player has dived. "It should be football people - ex-players who know the game," he said. You could have a panel of three and rotate every week. There are a lot of people out of work who can be called onto that panel. You would need someone from the Premier League to adjudicate on it. Let them decide on punishments. Pulis's criticisms were endorsed by his goalkeeper Asmir Begovic, who accused Marriner of indecisiveness and costing them the game. "I think the hesitation in the decision was most disappointing," said the Bosnia goalkeeper. He wasn't going to give it at first, then he changed his mind. We still had to make sure we defended the free kick, but it cost us. The Stoke camp could easily be accused of hypocrisy for their outbursts because many of their players were tumbling following minimal contact, whereas the Snodgrass incident was an isolated case of a Norwich player being accused. Charlie Adam was the worst offender and was booked when he threw himself down after brushing against Johnson. Adam was later lucky not to receive a second yellow when he fell after coming in proximity to Steven Whittaker. Norwich City, however, deserved to win and Johnson said: "If we carry on like this, I'm sure we will finish in a similar position to last season or even higher."
