SNOOKER legend Stephen Hendry believes the sport's top stars are running scared of Ronnie O'Sullivan.

Seven-time world champion Hendry retired two seasons ago after an illustrious career in the green baize game.

But the former all-conquering Scot is amazed that few players have managed to stand up to the 'Rocket' since he packed his own cue away.

"I think other players are afraid of him now," said Hendry.

"It's what I had in the 90s - and it's a great feeling when you know people are scared of you.

"It's all about what Ronnie has got as well, it's something that I had in my prime.

"He starts so quickly and doesn't really give these players the chance to get into the match.

"He stops players from playing their natural game and straight away they're on the back foot because he gets out of the blocks so quickly.

"The only chances these players have got is if they can start like Ronnie - and that's hard to do.

"When you're intimidated, as it seems they are, it's not easy to beat him."

Five-time world champ O'Sullivan famously didn't play in a major tournament last season having taken a self-imposed snooker sabbatical to spend some quality time with his family and two young children.

But the 38-year-old, who kicks off his Dafabet World Championship title challenge at the iconic Crucible Theatre today against Finland qualifier Robin Hull - the world No.122 and lowest ranking player in the tournament - still came back and wiped the floor with the field in Sheffield despite a distinct lack of competitive action.

"In my eyes Ronnie is the clear favourite," added Hendry. "He's a level above the rest. He's the only winner really.

"I think the big thing with Ronnie now is that he only plays when he wants to play. That's making him happier as a person and he's enjoying his snooker a lot more."
