Andy Murray says he was not surprised that Lawn Tennis Association (LTA) performance director David Felgate was sacked earlier this week.
Murray was funded by the LTA but trained outside the system
New LTA chief executive Roger Draper dismissed Felgate, along with two other senior directors, on Tuesday.
"A lot of people were expecting it," said the British number two.
"It shows Roger isn't afraid of change and if he saw the standard Dave was achieving wasn't good enough, then you could argue that's a good thing."
Murray, who spent most of his early career outside the LTA system learning his craft in Spain, hopes Draper's arrival last month signalled the start of long-term change at the LTA.
Felgate spent three years in charge of performance, the same amount as his predecessor Patrice Hagelauer.
"There has been a lot of restructuring but nothing has really got a lot of time," said the 19-year-old.
"Patrice wasn't in the job long enough to make huge changes and neither was Dave.
"Hopefully, whoever comes in next will be given plenty of time because, with the standard of British tennis at the moment, it is difficult to make a difference in just three years."
Murray, 19, is widely expected to become Britain's only world-class player when Greg Rusedski and Tim Henman, both in their thirties, decide to retire.
But the Scot could be joined by talented Serbian teenager Novak Djokovic after his parents discussed a possible move to Britain with the LTA.
Djokovic is understood to want to become a British citizen and is a close friend of Murray on the tour.
"I don't have anything against it if he does want to become British," said Murray.
"It is his decision. I haven't spoken to him about it but if there is any truth in it then I'm sure I will."
