Cape Town - Former world number one Andy Murray has lashed out at the Lawn Tennis Association for the lack of growth in tennis in Britain.
The Scot believes that the LTA has failed to build on his success at the top level as well as the success of fellow Brits Johanna Konta and Kyle Edmund, who should have inspired a generation.
"I'm not sure Britain has really capitalised on the last seven or eight years of success we've had," the three-time Grand Slam winner told BBC Sport.
"Whether it be myself, my brother, Jo, Kyle, the Davis Cup, those sorts of things, I'm not sure how much we've done there.
"There are quite a few players coming through that have potential to go on and do better, but obviously you are talking about the high end of the game.
"Maybe it's something I should have given more thought to while I was playing but I never felt that was my job to do that. It is a little bit disappointing. I don't understand how in the last eight to ten years that participation is dropping - I don't get it.
"I know in Scotland that there have not been many indoor courts built in the last ten years. That seems madness. I don't understand why that is. You need to get kids playing; you need to have the facilities that allow them to do that."
Murray was knocked out in the opening round of the Australian Open on Monday and faces an uncertain future as he contemplates another hip operation.
