The iconic Alexandra Palace has held the Masters since 2012 but Ronnie O’Sullivan took issue with some of the conditions on Thursday.

The Rocket booked his place in the semi-finals against John Higgins, but was aghast at the state of Ally Pally.

“Everywhere’s just dirty, it’s cold, I’m freezing,” he said. “I have to sit here in my coat. Everywhere you go, you’re going through car parks, it’s bins.

“I don’t know if you’ve seen over there [media catering area] there’s leftover food and stuff and it makes me feel ill to be honest with you.”

The World Snooker Tour have since responded and said that they are “disappointed” by the criticism, throwing their backing behind the venue.
