World No.2 Novak Djokovic has split with coach Boris Becker.
The pair worked together for three years, with Djokovic winning six Grand Slams under Becker's tutelage.
“After three very successful years, Boris Becker and I have jointly decided to end our cooperation,” Djokovic said in a statement on his Facebook page.
“The goals we set when we started working together have been completely fulfilled and I want to thank him for the cooperation, teamwork, dedication and commitment.
“On the other hand, my professional plans are now directed primarily to maintain a good level of play, and also to make a good schedule and new goals for the next season.”
Djokovic recently lost the world No.1 ranking to Brit Andy Murray, after 122 weeks in the top spot.
