London:Andy Murray has split with American coach Brad Gilbert and will instead hire a team of experts to monitor his progress.
Murray, Britain's top-ranked tennis player at Number 11, had been working with Gilbert since July 2006 in a partnership funded by Britain's Lawn Tennis Association.
"Despite being injured for almost four months this year, I am pleased with my 2007 results and am very grateful for the help that the LTA have given me by providing Brad Gilbert as a coach but the time has come to move on to the next stage of my career," Murray said in a statement on Wednesday.
"I am ranked 11 in the world and can now afford to pay my own way and so will now hire a team of experts, each to fulfill a specified role in the development of my tennis and fitness."
LTA chief executive Roger Draper said Murray's success was "vital" for British tennis.
"It is essential that he has a team around him that will allow him to fulfill his potential," Draper said. "We are currently reviewing the situation in relation to Brad and will look to make a decision in the near future."
Gilbert was hired by the LTA to coach at all levels within British tennis, but with Murray as his priority.
Murray has won ATP Tour titles in San Jose and St Petersburg this year and reached finals in Doha and Metz.
Gilbert, a former tour player, coached Andre Agassi from 1994 to 2002 - a span in which Agassi won six Grand Slam titles and reached a Number 1 ranking.
Gilbert also worked with Andy Roddick when he won the US Open in 2003.
The 20-year-old Murray split with his first coach, Mark Petchey, in April 2006.
