Barcelona, Real Madrid battling for Gremio sensation Douglas Costa

Barcelona and Real Madrid are battling for Gremio star Douglas Costa.

The 18 year-old midfielder is regarded as a bigger talent at the same age as Manchester United's Anderson and has already seen his buyout clause increase to £18 million in anticipation of his sale.

United are also following Douglas Costa, but Barca and Real have the inside-running as the youngster is keen on pursuing a career in Spain.
