Phil Mickelson, Lee Westwood & Dustin Johnson contacted over Saudi Arabian-funder super league

Most of the world's top 100 players have been asked to join a Saudi-funded super league, says Phil Mickelson.

England's Lee Westwood revealed on Wednesday that he has signed a non-disclosure agreement (NDA) that prevents him from discussing the issue.

Another former world number one, Dustin Johnson, has hinted he too has an NDA.

When asked if he had been approached, six-times major winner Mickelson said: «Pretty much every player in the top 100 in the world has been contacted.»

It has been reported that Westwood's Ryder Cup team-mate Ian Poulter is considering a £22m offer to sign up with the Saudis.

BBC Sport understands another current European Ryder Cup player turned down a £7m offer to sign up. Unlike Mickelson, Westwood and Poulter this player is not competing at this week's Saudi International event in King Abdullah Economic City.

The super league is expected to be the next step by the Saudis, who have ploughed £300m in to the Asian Tour to create a 10-tournament International Series, fronted by former world number one Greg Norman's Liv Golf Investments.

The International Series, which plans to run for the next decade, includes an event at the Centurion Club in Hertfordshire this June and is being funded by the Saudi's Public Investment Fund, which was also used to buy Premier League Newcastle United last year.

Norman says the Series «is just the beginning» and he is expected to serve as commissioner of the proposed super league.

It would be a limited field Formula One style circuit that would include a team element as well as individual competition.

«I think it's a really good concept,» said current world number five Johnson. «I think it makes it a little more interesting for the fans and for the players.»
