Ronnie O'Sullivan's 20 years at The Crucible

BBC Sport looks back at some of Ronnie O'Sullivan's most memorable moments at Sheffield's Crucible Theatre as 'The Rocket' confirms he will return to the game at this year's World Championships.

O'Sullivan clinched a fourth world title in 2012 before announcing he was to take a break from the game.

In November it was confirmed by World Snooker boss Barry Hearn that O'Sullivan would miss the remainder of the 2012/13 season , but the player has announced he will defend his title in April.
