Despite the accomplishment, the Serb wants to possibly give another shot at the 2028 LA Olympics and feel pride in representing his country and sharing the village with other sporting stars, echoing the true spirit of being a sportsman."The only thing that at this moment, professionally speaking, I have in my vision at this point, and it's interesting when we talk about these achievements and the Olympics that stand out and redemption, the only thing that I have in my head which gives me motivation is the Olympics on the 2028 in Los Angeles. And playing for the national team and Grand Slams."He added:"But not even the Grand Slams, not as much as the Olympics. I kind of watch the cycle, somehow, just to be at the Olympics, to be an Olympian. That moment when you wear the coat of arms of your country, when you go to be in the village with the best Olympians, that feeling, that's sport."Djokovic is the only player to achieve the Career Grand Slam three times in his career. His resume boasts 100 singles titles, including 72 Big Titles.
