Two-time French Open finalist Alex Corretja will coach Andy Murray during the clay-court season.
The 33-year-old Spaniard, a former world number two, will work with Murray at events in Valencia, Monte Carlo, Rome, Hamburg and the French Open.
Corretja will work alongside Miles Maclagan and physical trainer Matt Little for a nine-week period.
"It is great for me to be able to work with a clay-court specialist like Alex," Murray told his website.
"He had a fantastic career and I am looking forward to learning from his experiences."
Corretja said: "I have watched Andy play several times over the last couple of years and in particular his close match against Nadal in Madrid in October.
606: DEBATE
"(I) saw that he has tremendous potential to play well on all surfaces and I am flattered to have been asked to be part of his team during the clay-court season."
Murray has won two titles in 2008 but also suffered some disappointing results, including the defeat by Mario Ancic in Miami last week when he wasted two match points.
The 20-year-old Scot missed most of the clay-court season last year after suffering a serious wrist injury in Hamburg.
He has been working with a team of experts instead of one coach this season after parting company with Brad Gilbert last year.
Corretja was twice a beaten finalist at Roland Garros - in 1998 and 2001 - and was ranked number two in the world in 1999. He won 17 titles before retiring in 2004.
Murray will play his first clay event of the year in Valencia from 14 April.
