Murray made the call in a op-ed for the International Olympic Committee (IOC) on International Women's Day, urging the tennis world to address its gender imbalance. 

An International Tennis Federation (ITF) Global Tennis Report, published in 2019, found that only 21 per cent of the world's 164,000 tennis coaches were female.

The two-time Olympic singles champion revealed he thought that tennis was "the best in terms of equal prize money and male and female players competing at the same events," but that the sport still had a lot to do in terms of gender equality. 

He cited the appointment of Amelie Mauresmo as his coach in 2014 as an example. 

"The reaction to Amelie’s appointment as my coach, even from people close to me, was when I realised there was a problem," Murray said.

"The reason they were questioning her was purely based on her sex, it was not because of her ability or what she’d done in her career."  

Murray also pointed out that only 11 per cent of accredited coaches at the Rio 2016 Olympics were women, and that this needed to improve. 

"The best coaches should be the best people and, at the Olympic Games, there’s no way that women should represent only 11 per cent of the best coaches – clearly more work needs to be done here," he said.

"When it comes to mindset, skillset and intelligence, there’s no reason why a woman can’t be just as good as a man and hopefully things will change when women are given more opportunities."

He also suggested that International Federations look at introducing mixed doubles disciplines, having enjoyed competing with American Serena Williams at Wimbledon in 2019. 

"When I played mixed doubles with Serena Williams at Wimbledon last year, it was a good example of how the format draws a slightly different crowd to the sport. 

"Normally when I win or lose at Wimbledon, people will come up to me and say: 'Well done' or 'Bad luck'.

"But, with Serena, so many people said: 'We loved seeing you and Serena playing together. It was brilliant'. 

"People enjoy seeing that, and we should promote it. 

"How can you not see that it’s a good thing."

Murray, 32, claimed Olympic gold at London 2012 and Rio 2016, also triumphing at Wimbledon in 2013 and 2016.

He earned another Grand Slam title at the US Open. 

The IOC recently introduced two measures to further improve gender equality at the Olympic Games.

A limited number of additional quota places will be awarded to National Olympic Committees to ensure they are represented by both genders, while flags can now be carried by one man and one woman at the Opening Ceremony.
