Ronnie O’Sullivan was reminded about Hossein Vafaei’s comments from 12 months ago that he should retire from snooker, after being told the Iranian could be his opponent in the last 16 at the World Snooker Championship. Should Vafaei beat Ding Junhui in the opening round, he will face O’Sullivan at the Crucible on Friday, following The Rocket’s battling win over Pang Junxu.
