Novak Djokovic has completed tennis, winning everything a player can dream of and staying at the top of the sport for a truly incredible amount of time. The former world No. 1 fulfilled his last big dream in the summer of last year, when he finally won the gold medal at the Paris Olympics at the end of a run that left everyone speechless.

The former coach of pros like Serena Williams and Holger Rune believes it's not Djokovic's old age but his mentality that is holding him back from a 25th Grand Slam.

Patrick Mouratoglou has become a bigger star than most players, and is building an empire, too. That does not leave much time for coaching, and that may be just how he likes it.

Carlos has already won two Roland Garros crown at 22, looking destined for more. Still, Mouratoglou pointed out that beating Nadal on clay in his prime is an entirely different challenge! The renowned coach estimates that even a player of Carlos' caliber would only win two or three of ten matches against Rafa in his kingdom on the slowest surface.

Patrick Mouratoglou has highlighted Carlos Alcaraz's serve as a model of relaxed power. The famous coach pointed to two technical cues: the exceptionally high lift of his right led and the deep extension of his left arm after contact.
