Amelie Mauresmo will offer Andy Murray the same sharp insight as mum Judy, according to the Wimbledon champion's brother Jamie.
New coach Mauresmo will help Murray break uncharted territory when he launches his SW19 title defence next week.
Mixed reactions met Murray's move as the first men's grand slam winner to appoint a female coach, Australian Marinko Matosevic vowing not to follow suit.
Jamie Murray became Britain's first Queen's Club doubles finalist since 1993, then backed his brother's decision.
The 28-year-old said Fed Cup coach Judy Murray single-handedly shaped the careers of her sons, leaving Mauresmo's appointment no surprise.
"Our mum is probably the main reason we're here today: she was the reason we got into tennis," said Jamie Murray.
"She was a great coach for us growing up.
"Even now she still helps me sometimes, and still helps Andy on occasions.
"All through our careers she has been there for us when we needed her, not as much now obviously as we are grown up and fend for ourselves a bit.
"You can have all the knowledge in the world but if you can't communicate that then it is wasted, and I think she is a great communicator.
"I think all the people who have worked with her would tell you that; that's probably her greatest asset.
"I guess she knows when to speak and when to listen.
"That comes with communication skills; that's something she's great at, but not everyone is.
"So it's not a big deal for Andy to have a female coach - for most of his life that's what he's had.
"For anyone the most important thing is that you've got someone in your corner you trust and believe in and are able and willing to accept advice from."
Andy Murray relinquished his Queen's crown with a disappointing third-round defeat at the hands of Czech Radek Stepanek.
The 35-year-old battler was delighted to beat the "home darling", ending Murray's 19-run streak on grass.
Last summer Murray's Queen's victory vaulted him into the form that allowed him to become Britain's first Wimbledon champion for 77 years.
Brother Jamie said none of that would have been possible had mother Judy not launched a first-class coaching career with little or no support.
"No one taught her how to be a coach - she taught herself," he said.
"She started up at Dunblane and she ended up being national coach of Scotland.
"Now she is Fed Cup coach. She's done a lot of great things for tennis in Scotland.
"She brought a lot of kids through the game to a high level that otherwise wouldn't have had that opportunity.
"Hopefully she'll have her centre built and she can help many more kids."
