Real Madrid coach Carlo Ancelotti was impressed by Fran Garcia last night.
The Rayo Vallecano fullback featured in the 2-1 defeat for the visitors.
Former Castilla fullback Garcia will be re-signed by Real Madrid at the end of the season.
Ancelotti said: “He's a left-back with real energy and he's so quick with the ball. He plays out very well and he's got great attributes for us.
"He'll be with us next year."
