The Serie A outfit are among the clubs monitoring Tevez's situation but have yet to firm up their interest.
Corinthians insist they will not raise their £35m offer. But the Brazilians are convinced Tevez wants to join them.
President Andres Sanchez said: "I will not increase the offer by a cent. Tevez does not want to remain in Europe. It depends on Manchester City and the player's decision means a lot."
