Robbo fires Rocket warning

Neil Robertson has warned reigning world champion Ronnie O'Sullivan against taking on World Snooker chairman Barry Hearn.

O'Sullivan is the only player out of 96 pros to refuse to sign the players contract, with the Rocket unhappy at the amount of tournaments he would be obligated to play in and a lack of appearance cash. Robertson, who won the 2010 World Championship title, believes O'Sullivan is fighting a losing battle by taking on Hearn. ""In some ways I don't blame Ronnie for trying it on. Other players are unhappy with aspects of the contract. You get pay rebels in other major sports around the world," he told the Express. "But Barry Hearn is in a very strong position. Everything he has said he would do he has done. You can't have one person bigger than a sport." O'Sullivan revealed he was planning to take a six month break after landing a fourth world crown earlier this year and will not be involved in the Wuxi Classic. There are concerns as to whether or not Hearn will allow the biggest star of snooker to compete in the UK Championship in December, the Masters at the start of next year or the 2013 World Championship if he does not agree to sign the contract, or a new contract later in the year.
