Andy Murray says he would "always be on the end of the phone" to help Emma Raducanu - but only if she asks for it.
The 18-year-old won the US Open title on only her second Grand Slam appearance, catapulting her to 23rd in the world and global fame.
Former world number one and three-time major champion Murray previously said her achievements were "very special".
But he will not "wade in" with advice and opinion, because he did not like it when he was on the receiving end.
"I never really liked it when all of the ex-British tennis players were always wading in after every win and loss about what you should be doing, what you shouldn't be doing, and a lot of them also giving advice when you haven't asked for it as well," he said.
