Iran's Hossein Fafai criticized the Crucible Theater, saying the venue “really stinks”, the practice room was like a “garage” and the world championships should be moved elsewhere.
With a capacity of just 980 people, the Crucible has hosted snooker's biggest competition every year since 1977.
Many believe the current contract expires in three years, after which the event should move from its Sheffield home.
“Should I be honest? Do I enjoy being here?” the 29-year-old asked.
“History is very important, but no one invests their money in this historic place. I'd rather go somewhere really nice. When you walk around the Crucible, it really stinks. I’ll be honest: Everything is so bad.”
Buffai has played at the Crucible in each of the past three years, losing 10-5 to world No. 2 Judd Trump in the first round of the 2024 tournament on Sunday.
However, Iranians want the tournament to be held in China or Saudi Arabia, the country that hosted its first snooker tournament in March with the World Masters of Snooker.
“When you go to top venues in other countries, you see how wonderfully hospitable they are, how wonderful everything is, so shiny and so different,” Vafaei added. “If you ask me if I want to come back here, the answer is no.
“Practice room? Is there anything special? I feel like we're practicing in the garage, and that's not good. I'm coming here from another country to see it. I'm sorry. , I have to tell you the truth. “
