Gremio are battling to ward off Spanish Liga clubs from their 17 year-old attacker Douglas Costa.
Real Madrid, Villarreal and Sevilla are all chasing Douglas, who was described as "the new jewel of Brazilian football" by Gremio president Paulo Odone.
Douglas's buyout clause is £5 million and Real have already been in contact with Odone about a deal which would see the youngster remain in Brazil for another 12 months before moving to Madrid as an 18 year-old.
