Alexander Zverev stunned world number one Novak Djokovic in straight sets to win the season-ending ATP Finals and are the biggest victory of his career. The 31-year-old Djokovic was the heavy favourite but was outclassed 6-4 6-3 by the German. “It's quite astonishing, winning this title, beating two such players back-to-back, Roger and Novak, in semi-finals and final. It means so much. I'm incredibly happy and incredibly proud of this moment right now. I wasn't trying to overthink it. I just tried to go out there and enjoy the match as much as I can, enjoy the atmosphere, enjoy the moment. That's what I did,” said Zverev. Zverev revealed how Ivan Lendl helped him in the preparation to the match against the Serb. “He obviously analyzed the match that I played with him a few days ago, told me a few things I had to do differently. I was more aggressive today', said Zverev. “I tried to take the ball earlier. Those kinds of things. But my dad is the one that gave me the base. My dad is the one that taught me the game of tennis. I'm very thankful to him for that. Obviously, Ivan, the experience he has on and off the court, is amazing. That helped me, as well, to kind of play the two matches that I played back-to-back now.”
