Wearing a black coat in the aftermath of his triumph, O'Sullivan raged: “I just don’t like this place, I find it disgusting.
“Everywhere is dirty, cold, I’m freezing. I have to sit here in my coat.
“Everywhere you go, you’re going through car parks, there are bins.
“I don’t know if you’ve seen up there, there’s food and stuff and it makes me feel ill to be honest with you."
O'Sullivan then proceeded to admit that cleanliness was a big thing for him.
“I’m a clean freak. When I come here, it gives me the heebie-jeebies and I can’t wait to get out of here," he added.
"I’m sorry, that’s just how I feel.”
O'Sullivan also admitted that constant travelling had taken a toll on him, revealing he's not playing at the peak of his powers at the current moment in time.
"Maybe I've played a lot since September," he confessed.
"For me I've played a lot, travelled a lot. I've played a lot.
"Backwards and forwards from China, which takes it out of you.
"Trying to do everything can be hard and I think you can, especially at my age, it can take a little bit out of you.
