Disillusioned NSW rugby league coach Phil Gould says he's quitting the sport at the end of the upcoming State of Origin campaign.

Gould, angered by phone sex scandal which has dogged his team in the past week, said he'll quit after the current series.

In his column in The Sun-Herald newspaper, Gould said he was "filthy" at his players.

Centre Mark Gasnier was kicked out of the team on Thursday for making an obscene phone call to a woman in the early hours of Wednesday morning.

The call was made from the mobile phone of winger Anthony Minichiello, who was expelled from the team on Friday for having the phone with him after players had been forbidden from using them.

Five other players were fined a total of $20,000 for misbehaviour.

"I am not a football coach any more and I don't want to be," Gould said.

"A group of my players have done the wrong thing and I'm filthy ... I cannot begin to tell you how much that hurts."

Gould said he refused to be treated like a fool by his players, who had failed to respect his orders.

"I can't remember a time in my coaching career when I have been more disappointed than I am right now.
