Andy Murray has confirmed that Brad Gilbert is the coach he wants to take him to the next level in his career.
Murray is keen to work with Gilbert
The 19-year-old Scot, who reached the fourth round at Wimbledon, has not had a travelling coach since splitting with Mark Petchey in April.
"It is not a done deal, but I've spoken to Brad," Murray told tennis great John McEnroe on BBC Radio Five Live.
"He's got a very good record as a coach and he is somebody that I'd like to work with."
The American, a former top five player who won 20 singles titles, helped both Andre Agassi and Andy Roddick to top the world rankings.
Am I going to go and train in the States? Am I going to stay here? Is Brad going to work for the LTA?
Andy Murray on the issues still to be resolved
Gilbert has held discussions with the Lawn Tennis Association, which has said it would help fund him to coach the rising British star.
It is unlikely Murray would currently be able to afford Gilbert, who would command a large salary, possibly in the region of £500,000.
But it is understood there are some at the LTA who are unhappy about spending so much money on one individual.
Gilbert, who currently works for US broadcaster ESPN, has also expressed reservations about being away from his family for long periods.
And Murray is still unsure about how any deal with the 45-year-old would work.
He added: "Am I going to go and train in the States? Am I going to stay here? Is Brad going to work for the LTA? It's not completely done yet."
