Roma striker Adriano has not attracted a transfer mandate from Corinthians as they side-step the question.
The hitman was linked with a return to Brazil after being invited to join them by Ronaldo.
However, Corinthians maintain they are not keen on him.
"We have never spoken with Adriano," Corinthians president Andres Sanches is quoted as saying on Tuttomercatoweb.com.
"It was Ronaldo to say Adriano would have been a good replacement for him, but there is nothing."
