The 18-year-old will now spend the next year with the newly-promoted La Liga club, as he looks to gain first-team experience.
He joined the Spanish giants from Dinamo Zagreb last summer, but made just one senior appearance.
Halilovic has made seven appearances for the Croatian national side, winning his first cap at the age of 16.
