Novak Djokovic has split from coach Boris Becker after three years working together.
Djokovic hired the former world number one ahead of the 2014 season in what was widely seen as a surprising move, but critics were silenced as the Serbian won six grand slam titles and dominated the sport.
Announcing the news on his Facebook page, Djokovic said: "After three very successful years, Boris Becker and I have jointly decided to end our cooperation
"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. In this regard I will make all future decisions."
Former Tottenham captain Ledley King wants to resurrect his coaching career with the club next year.
King retired four years ago due to a persistent knee injury and worked briefly with Spurs' under-18s in 2014.
The 36-year-old took a break due it being too much too soon but now plans to approach the club's head of coaching and development John McDermott about a fresh coaching role.
"It's something I will get back into, hopefully going into next season," King told Press Association Sport.
"I'm lucky to have the club here so it'll be a case of speaking to the right people, John McDermott maybe, who helped me start it up, and getting it back on track.
"I need to give it a good go and see if I'm any good. I started my badges and then stopped them. I was working two days a week with the under-18s here.
"Everyone asks players if they want to go into coaching and expect them to be the next best thing in management. I don't know what I'd be like.
"It'll be a learning process for me. It's like starting all over again. First I have to be good at what I do. If I feel I can be good then I can step by step start thinking about future roles."

Marathon runner Callum Hawkins has become the first British athlete to be selected for next summer's World Championships in London.
The Scot, 24, who finished an impressive ninth at the Rio Olympics in only his third marathon race, has been confirmed by British Athletics as the first member of its team for August's showpiece.
British Athletics performance director Neil Black said: "We are delighted to confirm Callum's selection for London. He has only competed over 26.2 miles three times, but we can already see the talent he has, finishing eighth at the London Marathon in 2016 and following that up in Rio at the Olympics with a brilliant ninth place."
Black added that the British team for the London World Championships would be "large and competitive".
George North will not play for Northampton again until he has been assessed by an independent expert in head injuries.
The Welsh wing, who has suffered a series of concussions, was cleared by Saints medics to continue playing during Saturday's Aviva Premiership clash with Leicester despite replays suggesting he had been knocked out following a tackle from Adam Thompstone.
Questions have been raised about whether the player's welfare was best served by his return to action but Northampton insist they were fully in compliance with World Rugby's head injury assessment protocols.
The club does admit, however, that the footage available to them at the time was limited and have taken the precautionary steps of withdrawing North from action pending the specialist's verdict.
