London: Novak Djokovic believes the thrill of becoming a father has provided him with the perfect motivation to win yet another ATP World Tour Finals title and end the year as the world number one.
Djokovic became a father last month when his wife Jelena gave birth to a baby boy named Stefan.
The world number one arrives at London's O2 Arena for the Tour Finals, which get underway today, as strong favourite to become the first player to win the prestigious event three times in a row since Ivan Lendl in the 1980s.
"My wife and I had the blessing of becoming parents recently and it's the most beautiful thing we can experience.
First tournament after that happened was Paris and I won it without dropping a set," said Djokovic, who opens his campaign against US Open champion Marin Cilic on Monday.
"We should be making more kids I guess! It was a fantastic week and hopefully I can follow it up."
