Real Sociedad winger Mikel Oyarzabal has signed a new deal to 2021.
The 18-year-old's contract had been due to expire in 2018, but he has now signed a three-year extension after an impressive breakthrough season at the Anoeta.
"It's a dream come true, Real is like a family to me," Oyarzabal told Real Sociedad TV.
"I am very young and I have had many good things in a short time.
"I have to keep working so that everything remains the same."
