I guess Djokovic wont be retiring anytime soon but I honestly still want Djokovic to win this though. Anyway they are both 16 years apart and by the time Djokovic started his professional career, Alcaraz is still a few months infant they are totally both coming from a different era
I really don't know though, but one thing I know for sure is that whichever one of them wins the title have more than earned it here, you get. I really do love Djokovic too, and I love the fact that there is at least one veteran out there active in tennis showing these young generation players the need for consistency, because I can't imagine if the likes of Ruud, Rune, Tsitsipas, Sinner and co, are all we to compete against Alcaraz for the top ranks in tennis, that means there is becoming some level of decline in the sport quality over time, because most the mentioned players are top 10, and I don't believe I'm seeing distinct improvement in their level of competitiveness, not if a 36 years old Djokovic is having relatively easy against any one of them, I mean no disrespect Djokovic because he manage to keep himself fit and stay agile over the years, and this really should be the time that these young players begin to stress him according to his age, but they barely look as fit as Djokovic does.
I am sure Alcaraz will not be impressed though and will want revange for RG. His problem could be that he will want it too much and maybe force it a bit which will result in unforced errors. It is really a fine margin to walk to get a perfect amount of aggressive play against Djoković.
