Internacional midfielder Sandro is a target for Spanish giants Real Madrid and Barcelona.
The youngster is expected to leave Inter in January, with Tottenham in advanced negotiations over an £11 million deal for the 20 year-old.
But Real and Barca are also keen and are planning to table rival offers for Sandro ahead of the winter market.
Sandro is regarded as Brazil's brightest young player and has already been called up by Dunga to the senior national squad.
