One thing people ignore is that Alcaraz has now reached the Quarters or better at all the slams and he's only 20. A lot of the hate towards Alcaraz is because he's seen to be the player who puts the nails into the Djokovic coffin, ultimately Djokovic doesn't have that long left on tour.
He's a talent, he's young and there is still room for improvement. I like him, I like his fight, his style and I hope he stays injury free and wins boat loads of Slams. He's a two time slam winner.
Why suddenly turn on him? My worry about Alcaraz is that Djokovic lives rent free in his head after Cincinnati, he doesn't need that mental baggage.
