Since winning Wimbledon, Novak Djokovic had lost just two matches going into the ATP Finals winning the Cincinnati Masters, US Open and the Shanghai Rolex Masters in the process. From being ranked outside the top 20 at the start of the year, Djokovic rose to the top of the rankings at Shanghai and in the process became the oldest ever player to finish the year as World Number 1 at the age of 31 years and 223 days.

The Serb looked in devastating form going into his final with Zverev, winning all sets without getting broken even once. Djokovic who faced just 2 break points until the final, uncharacteristically was broken thrice by Zverev in the final.

Just like Karen Khachanov shocked Djokovic and the tennis world in the final of the Paris Masters, Zverev stunned his opponent who is 10 years his senior at the O2 Arena, London. Djokovic has to wait until 2019 to equal Nadal's tally of 33 ATP Masters 1000 titles. Results of the last month have shown that even the impregnable Novak Djokovic can be beaten.
