Reports in both Brazil and Spain claim Real put Neymar through tests over the weekend, with a view to signing a contract that would see him joining in the summer of 2012.
"I have been sold around 30 times already," he told Lancenet.
There is no truth in those rumours. I am a Santos player and I will stay here for the club's centenary."
He also confirmed that he had been to hospital but for personal reasons only, adding: "I went to the hospital to solve a personal problem. The rumours are just speculation. There is no deal at all."
