Andy Murray concerned about his homeland legacy with indoor facilities still limited in Scotland

• e-mail

Andy Murray has admitted he fears his career will end without Scotland having truly capitalised on his remarkable success.

The Wimbledon champion could follow brother Jamie's lead at the ATP World Tour Finals this weekend by ensuring he finishes this year at the top of the world rankings.

And Andy, who despatched Stan Wawrinka 6-4, 6-2 on Friday to secure his place in the last-four in London, has voiced his concerns that his legacy could be squandered.

Andy Murray admits fears that his career will end without Scotland having truly capitalised

Judy Murray has backed plans for a new tennis centre, currently the subject of a public inquiry

'Obviously, I would be disappointed if nothing changed,' said the 29-year-old, who faces Milos Raonic on Saturday ahead of what could be a titanic tussle for No 1 with Novak Djokovic. 

'I'm interested in it for sure (but) there's not loads I can do about it just now whilst I'm playing.

'Obviously, my mum is heavily involved in tennis not just in Scotland, but in the whole of the UK. She's pretty aware of everything that's going on.

'I just hope that when I finish, it's better than it was when I started. Whether that's the case now or not, I don't really know.'

Scottish ministers are expected to announce their decision on the Park of Keir scheme soon

Andy has backed mother Judy's plans for a new tennis centre, which is currently the subject of a public inquiry. Scottish ministers are expected to announce their decision on the controversial £70million Park of Keir scheme, which would be on greenbelt land situated between Dunblane and Bridge of Allan, in the coming weeks.

Murray took such a keen interest in hearing both sides of the argument that he attended the inquiry as an observer when he was in Scotland in September, just days before Great Britain's Davis Cup semi-final against Argentina. 

'For my mum, it's something she's been working on for a very long time,' he added. 'I hope for her that it goes ahead. When I speak to her about it, she so wants it to happen.

'It's now like she's going to keep going after this. If it doesn't happen now, this will probably be the last chance. She's put so much time and effort into it. 

Since the Murrays joined the tour over a decade ago, very few indoor facilities have been built

'I know she's doing it for the right reasons. I hope for her that it happens. If not, it would be a shame.'

Since the Murrays joined the tour more than a decade ago, very few indoor facilities have been built, with covered courts particularly sparse in the north of Scotland.

Jamie has criticised Tennis Scotland for their part in this, although they are not helped by receiving less than £1m of funding a year from the Lawn Tennis Association, who have a total budget of around £60m.
