Andy Murray, the world's second-ranked player, says he is reuniting with former coach Ivan Lendl.
Lendl was Murray's coach for two years until 2014, during which time the British player won his two Grand Slam titles and Olympic gold medal.
Murray said Sunday he had "two very successful years working with Ivan" and that he is "looking forward to Ivan joining the team again and helping me try and reach my goals."
The news comes a week after Murray lost the French Open final to Novak Djokovic. Since Lendl's departure, Murray has lost three Grand Slam finals.
Lendl will be with Murray for the Aegon Championships at Queen's Club in London, which start Monday.
Wimbledon begins on June 27.
