ANDY Murray’s fortune is set to double to £120million after his Wimbledon final yesterday, experts said - boosted by the ace swopping his wild outbursts for David Beckham-style family appeal.

Murray, 29, is already worth £58m, mainly from sponsorship deals, the Sunday Times Rich List shows.

Marketing experts said he is in line to pocket another £60m in the next three years.

Sponsorship veterans said world No 2 Murray’s beefed-up appeal comes from calming down his rants and sulks now he has married Kim, 28, and become father to Sophia, born in February.

Experts said Murray’s fortune would rocket - even if he lost yesterday (Sun) - due to having a wider appeal, as with Beckham, whose family wealth has rocketed to £240m since he retired from football due to his combined family appeal from wife Victoria and children.

Beckham’s agent Simon Fuller also masterminds Murray’s sponsorship partnerships, which already include a £15m deal with Sportswear firm Under Armour, as well as deals with Head, Jaguar and Standard Life.

Murray’s wealth doubled from £32m before he won Wimbledon in 2013 to his current £58m, which includes a small slice for brother Jamie.

Veteran sponsorship consultant Nigel Currie, 55, whose former clients include Samsung, Barclays and Volkswagen, said: “Murray is a very hot property.

“He would be looking at easily seeing his current worth double over the next three years.

“Sponsorship deals are attracting bigger and bigger sums for players and his money will keep going up.

“His family make him more and more marketable as he attracts wider media coverage now, as celebrity families do, and that makes him even more marketable.”

Marcel Knobil, 52, of marketing firm VeryFirstTo, who has worked with Coca Cola, Yamaha and Braun, said: “As long as Murray maintains momentum, he will be looking at pushing £100m of value within two years, and more afterwards.

“It is his family values which are also helping him on that positive trajectory.

“What’s key to Murray’s attractiveness to sponsors is that his personality has become much more appealing.

“His personality has been tamed. He has lost his edge and is connecting with people better, interviews better, is approachable and warm.

“Simon Fuller’s team have had that impact on his personality, and he is being very well nurtured by his management company.”
