All the background buzz about 14-year-old Laura Robson,which started little more than a week ago, came to a thunderous climax on Court One yesterday as she captured the Wimbledon junior title. Her 6-3 3-6 6-1 win over Noppawan Lertcheewakarn of Thailand made it a huge day for British tennis and as of last night, Laura’s life took a significant turn. The challenge now is to take care of all her current assets and shield her from all the side issues which could only distract from the main objective.

The breakfast-time discussion in the family home in Wimbledon today may not do anything more than prolong the celebration into this evening, when Laura will be feted alongside the senior champions at the end-of-tournament dinner in Park Lane.

Tonight, she thought she might like to wear a blue dress and sit with the Russian player and men’s semi-finalist Marat Safin, but after her match she said that Safin’s agent had given her a letter on Friday. “It says — I’ve got it memorised actually — ‘To Laura, I’m sorry I can’t come to the ball but good luck’. It was really nice. He’s turned me down unfortunately — but I think he’s a bit old for me anyway.”

Tomorrow Laura is due to set off for Holland for three weeks of tournament play at junior level while in an office north of Putney Bridge in London her agents, Octagon, will be overjoyed with the progress of their young client and might be able to gauge what kind of riches might come her way and plot the early stages of a sensitive course of action. Without doubt, massive rewards await winners. Venus Williams, the senior singles champion, won £750,000 yesterday and has lifetime prize-money of around £20m. Justine Henin of Belgium, who retired this year,won £2.5m in 2007 alone.

Laura has a racket deal with Wilson and one with adidas for clothing, and her agents will be able to assess other potential earnings that will relate to her newly-found teen hero status. Whatever, Laura’s cash will be mounting by the hour when things start to fall into place, and on current evidence there are no limits.

Just after Wimbledon began, Gerald Williams, a long-term reporter at the championships who is working for Sky, was told by Martin Mulligan, who was runner-up in 1962 and knows the game inside out: “You should see this English girl — she is the best girl player I have seen anywhere in the world for the past 10 years.”

Williams began to hear other views emanating from Australian sources — Mulligan is an Australian but has lived in Italy for years running the Fila clothing operation — and the evidence in support of Laura as the next British winner of Wimbledon began to mount, especially from Australia, where Laura was born.

She could not be more homespun these days. She has a British passport, lives within a five-minute walk of the All England Club with her parents, Andrew, an oil company executive, and Kathy, and is the hottest property that the women’s game in this country has had in years.

For the moment Laura is driving the family name hard but once Wimbledon is over and the furore surrounding her dies down, she will have to start to show if she can justify the optimism she has helped create.

“She is a hot property and it is a question of how her career is going to be handled by the LTA,” said Ann Jones, who was junior champion in 1956 and won the senior title in 1969, and presented the trophy to Laura yesterday. “The only unfortunate thing is that she is the only one. I hope she doesn’t get too much attention — when I was playing there were always two or three of us at the top. It is tough being the only one but she is a really good prospect, she seems to have the right temperament.”

One of the most interested observers of Laura’s progress is former British No 1 Annabel Croft, whose coach in her playing days, the Australian left-hander Owen Davidson, is another who believes Laura is heading for the heights. He told Croft: “There is your next British Wimbledon champion.”

“I think Laura is fantastic,” said Croft, who was the last British winner of the junior title in 1984. “I have been following her progress and I knew she was a fighter because she has never let go in any of her matches. She is very aggressive, no weaknesses, and she is the full package. After a couple of matches here she knew how to handle everything, photographers and so on. It’s a raw talent which is extraordinary. I think she will make the transfer to the Tour quite seamlessly, and you don’t have to get down on yourself when you get there. It is a soulless, selfish and self-absorbing life. There are not a lot of friends out there. I craved friends and I realised I was never going to get that from the Tour. It’s a totally unreal world . . . you just don’t know what is going to happen out there. But Laura is very complete, that game is only going to get better, she has a horrible \ lefty serve, she takes the ball early and before you know it you are on the back foot. For me tennis is in the head and that is where she is strong. I would say at this stage she looks tough but the Tour finds you out. I feel she will react well.”

When Laura starts a new week tomorrow she is certain to recognise that life has altered dramatically. Carl Maes, who runs British women’s tennis for the LTA and helped the Belgian duo Henin and Kim Clijsters on the way to the top, is likely to favour a similar route for his latest charge. That would mean Laura appearing on the main Tour at a late stage of next year. Maes said: “The nicest thing for Laura would be that we can leave her alone for the next six months, so she doesn’t start walking with her head in the clouds.”

Before this Wimbledon there was real concern about how the British women would perform and what impact, if any, they would leave on the tournament. In the end five started and of them only Anne Keothavong was in on merit, the rest having been awarded wild cards. There were just two first-round winners, Keothavong and Elena Baltacha.

Already the senior British players will know that there will be greater demands on them to improve or face the possibility of losing support from the LTA, which is itself under fire. No wonder that every step Laura Robson took at Wimbledon was watched so eagerly.

She has already trained with top players such as Martina Hingis, has set herself a target of being in the top 500 by the end of the year and carries a label from Ladbrokes to say that before this success she was 50-1 — she is now as short as 6-1 — to be Wimbledon champion by 2020. That is enough to aim at.
