Novak Djokovic says he feels fresher going into next week's ATP Finals than in previous years as he chases an elusive record-equalling sixth title.
Serbia's Djokovic, 34, is seeking his first victory in the event since 2015.
After missing out on a rare calendar Grand Slam at September's US Open, Djokovic took time off before returning to win last week's Paris Masters.
"I needed that break to rejuvenate and get ready for a strong finish to the season," said the world number one.
Djokovic has enjoyed another stellar season, winning the Australian Open, French Open and Wimbledon titles to move level with Roger Federer and Rafael Nadal on 20 Grand Slam triumphs.
