Input: (CNN) If the pinnacle of Andy Murray's career so far took place on the pristine green courts of Wimbledon, the world No. 1 owes much of his success to the rugged, red clay of Barcelona.

According to the academy's co-founder -- three-time doubles grand slam winner Sergio Casal -- less than 1% of the kids that he takes on will go on to become a professional. Despite the odds being stacked against each and every pupil at the academy, Casal says he knew Murray was different from the start.Murray returns to Sanchez-Casal AcademyWorld No. 1 unveils court in his name
