Macci on Alcaraz: "He'll have a double-digit number of Grand Slams".

Rick Macci, ex-coach of such great players as the Williams sisters, Andy Roddick and Maria Sharapova, recently spoke out on the case of Carlos Alcaraz.

Highly complimentary of the Spanish prodigy, he even allowed himself a most optimistic prediction about the latter: "Alcaraz is the youngest player ever to have done what he has done. This guy is so special in a way that the tennis world has never seen.

He's a generational talent. There will be obstacles. But at the end of this road, the Spanish magician will have a double-digit number of Grand Slams."
