Norwich boss Hughton admits confronting ref after Arsenal defeat
The spotkick opened up the door to the Gunners to over-run Norwich 3-1 on Saturday.
Hughton sought out the match officials following the final whistle, and was left frustrated by their explanations of the key decisions.
"We have only had one penalty all season, but we have had some poor decisions given against us," said Hughton.
"Sometimes there is momentum in a game, when the crowd start cheering, and sometimes people go along with those emotions.
"I will accept there was contact, but if he has pulled his shirt, he wont be the first player who has done that and in the balance of the game the referee has decided not to give it.
"We were on a day when the decisions went against us, but at 1-1 we did show a bit of naivety and we should have been good enough to keep it at that."
