"Negotiations have already begun. Corinthians are in contact with us," said Kia Joorabchian.
"His [Tevez] dream and mine is to see him back with Corinthians. He said he has a job that does not end there, he wants to return because he has the dream of winning the Copa Libertadores.
"Everybody is working to make this happen, I, Corinthians, Tevez, Adrian Ruocco (the other agent who work on Tevez).
"It is impossible to determine the situation, but I think it's close."
