Gremio attacking midfielder Douglas Costa has welcomed interest from Real Madrid.

"I am very happy that a club as big as Real Madrid has been watching me," the teenager told Marca. "I am proud.

"It is unusual that a club with so much prestige is interested in a player like me, with little experience in the Primera Division. I hope I can repay that gratitude someday by wearing the white shirt.

"Of course I would like to play for Real Madrid!"
