​Real Madrid have announced reaching a six-year deal with Real Sociedad right back Alvaro Odriozola.

The 22-year-old, who joined Sociedad's academy in 2006, made his senior debut in a 2-0 win against Malaga in January of last year and has gone on to make 50 appearances for the side.

"Real Madrid CF and Real Sociedad have agreed to the transfer of the player Álvaro Odriozola, pending the medical examination," Los Blancos confirmed via their official website on Thursday.  

"The player is linked to the club for the next six seasons."

Madrid did not specify a transfer sum, but reports indicate that they have paid €30m for the player, agreeing a further €5m in performance based add-ons.
