World No. 1 Novak Djokovic has won five ATP Finals titles but he hasn't made it all the way at the prestigious season-ending event since 2015. Djokovic captured four consecutive titles at the ATP Finals between 2012 and 2015 but then his dominance abruptly ended.
Since then, Djokovic has made two finals but both times ended runner-up. During his pre-tournament interview at the ATP Finals, Djokovic was asked why he has found it harder to reign supreme at the tournament in recent years, "It could be just the amount of energy that you spend during the season that you maybe don’t have enough left in the tank for that final push.
But also I lost some tight close matches against Dominic Thiem a couple of years, last year 7-6 in the third set in the semi-finals," Djokovic explained, per Arab News..
Djokovic acknowledges the difficulty of playing only top players
“It’s just playing at the highest level against the top eight players in the world.
Every single match is really high intensity, high demand from you that you have to be at your best. It could be the case of maybe a semi-full tank, just not being able to perform at your best every single match and that’s what it takes here.
It requires a lot of energy from every point of view in order to triumph in this tournament," Djokovic continued. “(Grigor) Dimitrov, Tsitsipas, Zverev were some of the winners in the last five, six, seven years, they all had their maiden big title won at the ATP Finals and for most of them they were qualified maybe for the first or second or third time, coming in, they’re fresh, they’re motivated, they don’t have much to lose compared to maybe some of us that have been there for a while, it’s a different feeling. So that could be also one of the reasons”.
