Novak Djokovic has split from coach Boris Becker.
The world No.2 Djokovic and six-time grand slam winner Becker have worked together for three years, with the Serbian winning six grand slams himself since joining forces with Becker in December 2013.
"After three very successful years, Boris Becker and I have jointly decided to end our cooperation," Djokovic wrote 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."
