Rory McIlroy has called for Greg Norman to leave his role as chief executive of the LIV Golf Invitational Series to end the "stalemate" engulfing the sport.
World number one McIlroy has been one of the most prominent critics of the controversial Saudi Arabia-backed circuit, which is locked in legal cases against both the PGA and DP World Tours.
McIlroy called for LIV to do more to end the bitter feud between the circuits in September, declaring: "the ball is in their court".
However, Norman said he had "no interest" in sitting down for talks with the PGA that same month and McIlroy believes his presence is harming the sport.
"Greg needs to go. He needs to exit stage left," McIlroy said ahead of the DP World Tour Championship in Dubai.
"He's made his mark, but I think now is the right time to say you've got this thing off the ground but no one's going to talk unless there's an adult in the room that can actually try to mend fences.
"There are obviously two lawsuits going on at the minute. There's the PGA Tour versus LIV and there's obviously this one that's coming up with the DP World Tour in February.
"Nothing can happen if those two things are going on. Right now, it is a bit of a stalemate."
The need to compete with LIV Golf has prompted the PGA Tour to increase prize funds for next year, leading Norman to suggest McIlroy and Tiger Woods – another critic of LIV Golf – should be "thankful" for what the breakaway circuit has brought to the game.
However, McIlroy believes everyone in golf should instead direct their gratitude towards 15-time major champion Woods.
"I've said this a million times, Tiger is the reason that we are playing for as much as we are playing for," McIlroy added. "Tiger is the reason that the stature of our game is where it is.
"The generation of Tiger and the generation coming after Tiger have all benefited from him and his achievements and what he's done for the game of golf.
"I don't think Tiger should be thankful to anyone for anything. I think everyone else in the game should be thankful."
