Wimbledon - Murray victory 'worth £100m'
The Sunday papers all try to put a figure on just how much a victory would be worth to the Scot over the course of his career, with the Sunday Times claiming that his wealth would reach nine figures should he claim his first Grand Slam title on the turf of SW19.
"He could easily end up north of £100m," said Philip Beresford, editor of the newspapers' famous annual Rich List.
The paper also quotes "a leading agent who handles one of Britain's big sports stars" as saying that a win would provide such a massive windfall.
"This match could easily mean £100m for Murray," the agent said, speaking on condition of anonymity.
"Remember that tennis is a global game like football and golf. He has some good sponsorships but winning Wimbledon could see him branch out into clothing lines and tennis or health clubs."
The Star on Sunday runs a similar piece, though one which is, unusually, more conservative than the one in the Times, predicting £50m over the next five years .
"Tennis is an incredibly lucrative sport. We haven't had a British champion for many years and Wimbledon is a huge theatre, so that gives him huge potential," PR guru Max Clifford told the paper.
"You are talking about £50million in the next five years if he wins. I can see clothing companies, drinks companies and someone like British Airways coming in for him."
The report adds that Murray's current deal with Adidas is worth £3m a year, but there is likely to be a bidding war for his endorsement should he win.
Nike already have deals with Roger Federer and Rafael Nadal and would be keen to muscle in. Pulling the strings for Murray will be his agent Simon Fuller, the man who created the Spice Girls and still manages David Beckham, so there seems little risk that the Scot will miss out on any decent chances for off-court earnings.
A Swiss watch firm is apparently keen on signing up Murray already, while Nintendo are said to be keen to make him the face of the new Wii U console when it comes out later in the year.
Then there are the exhibition matches: Murray will suddenly find he receives invitations to play one-off events where the going rate is $1m a go - that's £650,000 for a one-off game of tennis.
But Clifford warns Murray that he needs to be careful about what he agrees to do.
"He's got to be very selective in what he goes for and what he turns down – it's got to be quality rather than quantity," he said.
"Simon Fuller has been looking after Beckham for the last few years so he knows all about the endorsements, sponsorship and potential."
