Racing Santander coach Marcelino accepts they'll have to sell defender Ezequiel Garay at the end of the season.
The Argentine youngster is a target for Real Madrid and Marcelino told AS: "He is an authentic star. He is 21 years old and, despite measuring 1.87 metres, he is a genuine central defender.
"He is good with the ball at his feet and has a phenomenal aerial game. He reads the play before anybody else.
"I do not have any doubt that next season he will be playing for a big club.
"We must assume his transfer, we're a selling club."
