“Ronnie Ou0027Sullivan is among the big snooker stars in action at the 2021 Champion of Champions in Bolton, as are Mark Selby, Shaun Murphy, Mark Williams and Kyren Wilson. John Higgins is also involved, and the Scot made history with his 800th career century at the event last year. Neil Robertson, who comes in fresh from winning the English Open, triumphed in this event in 2019.”
