THE Brazilian was effusive. “It’s insane,” said Bruno Soares, reflecting on the extraordinary sporting achievement that encompasses an accumulation of six grand slam titles, two Olympic gold medals and a Davis Cup triumph for his partner Jamie Murray and brother, Andy.

Soares and Murray the elder won the US Open doubles title at the weekend to confirm that Scotland lives in the most glorious of days in tennis. The Murray brothers will this weekend play in their birthplace of Glasgow, prepared to lead Team GB to another victory in a Davis Cup victory.

But what of the longer-term future?

To borrow the words of Soares, it would be insane for Scotland to expect to produce another set of brothers who ascend to such heights, with Jamie once reaching world No1 in doubles and Andy merely a world No.2 in singles.

However, the Murray window of opportunity is closing with little to show for such success.

A bid to redress that desperate failing is now mired in an inquiry. The first application for a tennis, golf and football academy at Park of Keir, near Dunblane, was rejected by Stirling Council but now Judy Murray, mother of the tennis players and a principal force behind the proposed development, has appealed that decision. In the wake of his victory in New York, Jamie Murray backed his mother, saying that to leave a legacy, the academy “was the best way to do it’’. Evidence was heard last week at an inquiry under the auspices of the Scottish Government’s planning and environment appeals division.

Those who oppose the plans state it will impact adversely on greenbelt land. It would involve building a four-star hotel, a tennis museum and 19 homes. Murray has pointed out that the academy would be funded by the sale of the hotel and the homes and could not exist otherwise.

The development, though, strikes at the very core of how much Scotland wants to capitalise on the sporting legacy of the Murray brothers. The greenbelt issue can be debated and has been addressed in the Murray submission but other sniping must be put to rest.

There has been a whispering campaign about Murray being motivated by greed and/or vanity. The first accusation can be dismissed by pointing out that the building of the homes and hotel is necessary to fund the development. The development is designated as a charitable interest company, meaning all profits will be put back into the academy.

It is not an elite academy, either. The centre will operate a “mobile outreach programme”, taking tennis and golf to local schools and clubs from Auchterarder to Alloa, from Braco to Callander. The plan is to create a hub both to drive activity on existing courts nearby and to provide courts for children who have no courts in their village or town.

It has taken Murray four years of effort to come to this point. It has also involved expense that cannot be recovered.

But it is the accusation of a “vanity project” that raises the hackles of anyone who has watched Murray push for children to be given more opportunity to play sport.

Murray takes her Tennis on the Road initiative to all points in Scotland, attempting to both create a desire to play tennis in children and a coaching network to support that aim.

It is a relentless schedule that she undertakes with indefatigable energy alongside lead coach, Kris Soutar.

She is visible and available throughout Scotland though my favourite spotting was an autumn day in Drumchapel where the ground was coated with frost and rain slashed across courts with the venom of a Rafael Nadal forehand.

Murray, who can command substantial fees for public speaking and appearances, chose instead to coach groups of children for two hours, inviting hypothermia and rendering her coiffure somewhat bedraggled.

Driven, even obsessed? Perhaps. Vanity? Methinks not.
