Potting purist Shaun Murphy has warned whining Hossein Vafaei to stop going to the Crucible!
As he exited the first round of the World Snooker Championship, the Iranian, 29, unleashed a ferocious rant about the backstage facilities at the historic Sheffield venue.
According to the Prince of Persia, the Crucible stinks, needs a fresh coat of paint, and the practice rooms resemble garages.
There is talk that this tournament will be shifted to China or Saudi Arabia, where the prize money is higher and players receive VIP treatment.
But Murphy, the 2005 world champion, struck out at Vafaei, calling it “sacrilege” to disparage the Home of Snooker after nearly 50 years.
The Magician, who is 41 years old, said: “Maybe having not grown up in the UK, Hossein’s not as emotionally connected to this tournament as many of the UK players are?”
