Judy Murray on sons, coaching and legacy

“Forty-seven years I’ve been involved in tennis, I still love it as much as I always did and have a huge passion for teaching it but for the last 10 years or so I’ve sensed that we have the golden opportunity to grow tennis in Scotland,” she added.

“We are still very much a minority sport, we need a lot more public facilities, we need more tennis courts in schools and we need a much bigger work-force because it’s all about people – it’s people who make things happen, it’s not systems and programmes.

“We have terrible weather up here and we haven’t had one new indoor court, bar four at Gleneagles Hotel two years ago, in the 10 years Andy’s been in the top five.

“It’s very difficult to grow the game if you don’t have the facilities and a big enough work-force but that work should’ve been started about 10 years ago if somebody else had recognised the opportunity.

“I’m doing what I can to build the work-force. There’s a £15m investment that’s come via the LTA and Sportscotland given to Tennis Scotland to create more indoor facilities over the next five-to-10 years.

“But all these things take time and my worry now is that Andy and Jamie may only have two or three years left where they are motivated enough and fit enough to play at the top of the game and if we don’t move quickly, we’re actually going to miss that opportunity and to me that would be an absolute crime.

“It doesn’t matter what level you get to. I’m a huge promoter of getting kids active and leading a healthy lifestyle.

“It’s a difficult world to negotiate and very few do get to the top but it’s a wonderful sport, it’s a sport for life.”

Judy Murray was speaking to Geoff Webster on BBC Radio Scotland’s Sunday Sportsound.
