Andy Murray has parted company with his coach Miles Maclagan, bringing an end to a working relationship that had lasted almost three years.
Maclagan started working with the world number four at the end of 2007, after Murray had sacked his previous coach Brad Gilbert.
The Scot will, however, continue to work with former Spanish star Alex Corretja pending the appointment of a new coach and will review the situation after next month's US Open.
"I've had a great relationship with Miles over the past two-and-a-half years and I want to thank him for his positive contribution to my career," Murray said in a statement issued by management company 19 Entertainment.
"We have had a lot of success and fun working together."
Privilege
Maclagan, a former British Davis Cup player, said: "It's been a privilege to work with Andy as his coach and I'm happy to have played my part in his career.
"I also want to thank the team for all their hard work over the years and I will miss working with them and Andy on a day-to-day basis.
"Andy is a great player and I know he will continue to have the success his talent and hard work deserves."
Murray is currently in Los Angeles, where he is competing in the Farmers Classic, his first tournament since losing to Rafael Nadal in the semi-finals at Wimbledon.
With the 23-year-old yet to make a grand slam breakthrough and having also suffered poor form earlier this season, former coach Mark Petchey told Sky Sports News that Murray doubtless felt he needed fresh input.
"They've just got to the end of the road," Petchey, Murray's coach from 2005 to 2006, said.
Petchey added that things had gone "a little bit south" for Murray this season, prompting him to look elsewhere.
