Former world number one has recorded a poor run of results in the last four weeks
Twelve-time Grand Slam winner Novak Djokovic has parted company with coach Boris Becker.
Djokovic has worked with the former Wimbledon, US and Australian Open winner for three years.
The Serbian world number two won six Grand Slams under Becker and held all four major titles at the same time when he won the French Open final in June.
“The goals we set when we started working together have been completely fulfilled,” he said.
“I want to thank him for the cooperation, teamwork, dedication and commitment.”
He lost his world number one spot after 122 weeks in November to Britain’s Andy Murray in November, having exited Wimbledon in the third round and lost his opening match at the Olympics.
Djokovic, who had beaten Murray to win the French Open, then reached the US Open final in September before losing to Murray in the season-ending ATP World Tour Finals last month.
“My professional plans are now directed primarily to maintain a good level of play,” he added. “And also to make a good schedule and new goals for the next season.”
