Djokovic experienced at finding the energy to finish strong

Starting his ATP Finals campaign with an easy win, Novak Djokovic says he still has enough gas in the tank for the final weeks of the season.

Djokovic dismissed Matteo Berrettini in his opening round-robin match, but next up for the Serb are Dominic Thiem and Roger Federer, the other players in his ATP Finals group. He has to at least reach the final to have a shot at snatching away the No. 1 ranking from Rafael Nadal.

But even though he is coming off a long season that has included two Grand Slam victories and an elbow injury, Djokovic says he has learned what is required for a strong finish.

"It's probably a combination of things. Obviously I try to take care of my body the entire year," he told press at London. "I did go through some major injuries, thankfully not too many, and I value always the longevity and recovery and importance in my career very much. I try to surround myself with the right people and be professional, committed with the routines daily, because I know that in the long run that pays off" said Djokovic.

"That's probably one of the reasons why I have managed to be healthy and fit, but also because I think mentally, you know, you kind of are obliged to draw that last, I guess, drop of energy that you got in order to finish the season in the best possible way."

"So I kind of push myself and try to create even more energy for these couple of tournaments."

It's worked for Djokovic during his career -- he has captured five ATP Finals titles, including three back-to-back ATP Finals and Paris Masters titles. He also won the Paris Masters again two weeks ago, adding to his career success indoors.

"Knowing that... kind of every year gives me more motivation and confidence coming into these tournaments," Djokovic said. The 32-year-old also has Davis Cup in Madrid following the ATP Finals.

"I look forward to try to progress as much as I can here. Then I will think about Madrid," he said. "Should be fun, should be exciting. There is always this additional energy and motivation that you get when you're in the team. And when you're surrounded with your friends, playing for your country, it's just completely from any other event."

The second seed next plays Dominic Thiem in round robin competition at the ATP Finals.
