Dean Huijsen, 20, has made a success in Bournemouth this season.
Now the young defender is rewarded with a five-year contract at Spanish giant Real Madrid.
"Los Blancos" was one of several clubs that were after Huijsen, and won the tug-of-war after triggering the player's buyout clause of 650 million kronor.
Huijsen was recruited to Bournemouth from Juventus a year ago, and has made three goals and an assist in 30 appearances in the Premier League this season.
The Spanish national team player is one of the players challenging Antony Elanga for the award "Young Player of the Year" in the Premier League.
The recruitment of Huijsen is Real Madrid's first in this summer's transfer window.
