Corinthians have yet to receive an offer for Paulinho as the Brazilian waits to hear from his agent on possible interest from Europe.
The highly-rated midfielder, who featured for his country in the recent 2-2 draw with England, has reportedly attracted attention from several clubs.
Inter Milan and Shakhtar Donetsk have previously been linked with the 24-year-old and fresh speculation has suggested that Tottenham Hotspur and Roma are leading the chase.
However, Corinthians president Mario Gobbi is still waiting for an official bid, telling Folha de S. Paulo: "There have been no offers for Paulinho so far."
Paulinho is aware of the transfer talk and is in contact with his agent, who is currently in Europe, but he is also staying focused on the upcoming Confederations Cup.
"I am following what's happening, but there is nothing," the player told Lancenet.
"He is there (in England) and if there is something, I am sure he will tell me."
