Corinthians president Andres Sanchez insists their bid for Manchester City captain Carlos Tevez is not fantasy football.
Sanchez insists that Corinthians have a plan in place that will make them one of the biggest clubs in the world.
"Within three or four years, Brazilian soccer is going to be the world's richest. Just do the accounts," he said.
"The Corinthians have a recipe that no-one imagined two years ago. Corinthians will be, financially speaking, one of the world's strongest teams."
Sanchez said that their offer would remain on the table until January, adding: "He has until early next year to decide."
