Norman made the comments in separate interviews with ESPN and the BBC on Wednesday.

"I'll be honest with you, since Jon signed, I know he's been inundated by players saying, 'I want to play on your team, Jon. How do I get on that?'" Norman told ESPN.

"I know my phone is blowing up," the Australian also told BBC.

Rahm made the jump from the PGA Tour to LIV last week for a reported $566 million ($A860 million), most of it guaranteed.

Norman said the Spaniard's addition further validates LIV's 54-hole format and team competition.

"I think word is getting out there amongst all the players around the world, even the top players, the best players in the world," Norman said.

"It will create a domino effect, there will be more apples falling from the tree – no question about it, because LIV continues to develop." – Greg Norman. 

"They love our format, they love our platform, they love the team spirit, the team atmosphere. And to be honest with you, I've seen it resonate very, very loudly this year. And obviously, Jon is an incredible addition to us."

LIV begins its third season at Mayakoba in Mexico on February 2-4.

In the meantime, all eyes are on which golfers make the jump to fill out Rahm's team.

"It will create a domino effect, there will be more apples falling from the tree – no question about it, because LIV continues to develop," Norman added.
