Novak Djokovic has confirmed rumours that he and coach Boris Becker have parted ways.
The pair mutually agreed to end their three year partnership after a late-season dip in form.
Djokovic's win at the French Open saw him complete his career Grand Slam, but early exits from Wimbledon and the US Open and faltering form over the last two months allowed Andy Murray to snatch the world No. 1 ranking.
The 29-year-old explained the decision on his website.
"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."
