Greg Norman has hit out at the PGA Tour, saying it is "trying to destroy" the LIV Golf invitational series.

Norman, the chief executive of LIV Golf, has defended the new series on multiple occasions, with plenty of criticism from figures in the sport including Tiger Woods, Rory McIlroy and Shane Lowry.

Speaking to The Australian newspaper, Norman said LIV Golf is not trying to destroy other tours, insisting it is actually the other way round.

"This notion we're trying to destroy tours is not true," Norman said. "The PGA Tour is trying to destroy us, it's as simple as that. The PGA Tour has not sat down and had a conversation with myself or any of my investors.

"We tried awfully hard, I know I did personally for the past year. When we knew we were never going to hear from them, we just decided to go.

"We have no interest in sitting down with them, to be honest with you, because our product is working."

The latest LIV Golf event begins in Chicago on Friday, following the last one earlier this month in Boston, which was won by Dustin Johnson.

Some opponents of LIV Golf have expressed concern about Saudi Arabian investment in the series, due to that country's human rights record. Critics have made claims of 'sportswashing', which organisers have rejected.

There were several protestors in attendance in Boston, but Norman said he does not focus on the series' detractors.

"I don't even pay attention to that, to be honest with you," he added. "All I can tell you is I'm here for the game of golf. I focus on building the best league we can."
