After months of claim, counter-claim and controversy, the LIV Golf Invitational Series turns its focus to actual golf on Thursday.

The first event of a series previously known as the 'Super Golf League' gets under way at the Centurion Club, near London, next week.

A lucrative breakaway from the PGA Tour and DP World Tour, there will be plenty of interest in how LIV Golf fares – even if it is a largely unpopular venture.

Regardless of its wider reputation, though, the money of Saudi Arabia's Public Investment Fund (PIF) has still attracted some of the sport's best players.

So, what is the deal with LIV Golf? How does it work? Who will be playing? And why has it caused such uproar?

Stats Perform attempts to answer the myriad questions around this contentious competition.

What is LIV Golf?

A Saudi-backed rival to the PGA Tour has been rumoured for years, taking on various names before finally launching as the LIV Golf Invitational Series.

Greg Norman, a two-time Open champion and LIV Golf's CEO, has described this as the arrival of "free agency" in golf, with leading players skipping PGA Tour events to play in the new series.

That is exactly what the PGA Tour sought to avoid when it vowed to ban any players who joined a rival league, although that promise has not yet come to pass.

"Our mission is to modernise and supercharge the game of professional golf through expanded opportunities for both players and fans alike," reads LIV Golf's website, adding its aim to provide "a cutting-edge entertainment product".

That does not only mean a new series and new events, but also a new format...

How does it work?

Gone is the long-established structure of 72 holes across four days with the field cut after two rounds.

Regular season LIV Golf events will last only 54 holes and three days, with no cuts, meaning – organisers point out – there is no danger of eye-catching names being absent for the end of the tournament.

There are also shotgun starts, "ensuring a faster and more exciting pace of play", and smaller fields with only 48 players.

This may all be unfamiliar, but it is at least straightforward. The other changes are a little more complex.

Players will be pursuing individual glory, as at any other golf tournament, but there are also team prizes on offer, with each field broken up into 12 four-man teams.

At every event, there will be an individual winner – the traditional victor with the lowest 54-hole score – and a triumphant team, whose score will be calculated using their best two scores over the first two rounds and their best three from the third.

The first seven events of the season – four in the United States and one each in England, Thailand and Saudi Arabia – will provide a seasonal individual champion, while the year's most successful team are then identified at a further match-play knock-out tournament.

Who's playing?

With a number of big names publicly opposing the breakaway, Rory McIlroy referred to the then Super Golf League as the "not-so-Super League" back in February.

But LIV Golf claims to have received 170 applications and has been able to recruit some superstar talent – namely Dustin Johnson, whose agent said it was "in his and his family's best interest to pursue it".

"Dustin has never had an issue with the PGA Tour and is grateful for all it has given him," David Winkle added. "But in the end, [he] felt this was too compelling to pass up."

It remains to be seen how regularly Johnson will appear in the series, given the field is set to change for every event. He is on board for the London opener, though, alongside Sergio Garcia.

With the four-man teams – who will have their own logos, colours and names – to be tweaked at each tournament, captains will draft players to join them. Unlike at the Ryder Cup, these captains are also active players.

The opening London draft is set for Tuesday, but Phil Mickelson – the most notable and controversial potential LIV Golf star – will not be involved.

Given his previous interest, Mickelson is surely likely to appear at some stage, but he has not played for several months since his comments in relation to the tournament and its funding prompted an apology.

Why's it so controversial?

Any rebel league that threatened the PGA Tour was unlikely to be globally popular, but Saudi Arabia's influence has contributed significantly to the backlash.

The country's human rights record is of major concern, along with its role in the war in Yemen, so ventures such as these – and the acquisition of Premier League club Newcastle United – by its PIF are widely cited as examples of sportswashing.

Norman has suggested Saudi Arabia is "making a cultural change".

While he described the murder of journalist Jamal Khashoggi at the Saudi consulate in Istanbul in 2018 as "reprehensible", the LIV Golf chief added: "Look, we've all made mistakes, and you just want to learn from those mistakes and how you can correct them going forward."

Norman was speaking last month, by which point Mickelson's own discussion of Khashoggi's death had done a great deal of harm to the league's reputation.

The six-time major champion acknowledged Saudi Arabia's "horrible record on human rights" but added he was willing to commit to LIV Golf as it was "a once-in-a-lifetime opportunity to reshape how the PGA Tour operates".

Mickelson made those comments in November last year, although they were reported earlier this year just as the series sought to launch.

Norman said the saga "definitely created negative momentum against us" and revealed "everybody got the jitters", causing some players to back out.
