Golding emulated Murray by winning the boys' singles at the US Open last Sunday and this weekend he has travelled to Glasgow to join up with the world number four and the rest of the Great Britain Davis Cup squad for the tie against Hungary.
The 17-year-old saw what the pressure of the big occasion can do when British number two James Ward had to leave the court to be sick and also suffered badly from cramp before beating Hungarian number one Attila Balasz 6-4 6-4 4-6 6-4 Friday.
Murray, who put Britain 2-0 up with a 6-0 6-2 7-6 (7/3) victory over Sebo Kiss, said of Golding: "He's a big guy, which helps. He hits the ball well, he doesn't mind pace, which I think, with the way the game's going now, that's a good thing.
"The game's become so physical so that would be the number one thing to concentrate on, if I was giving any advice. It's taking guys much longer to break through now because of that.
"Physically he needs to try to get as strong as possible because that will stand him in good stead for when he starts playing in an occasion like this.
"For James, for example, when you are nervous and tense and you're playing five-set matches for the first time, it's a completely different ball game when you're playing against big men."
Golding was the first British boy since Murray in 2004 to win a junior grand slam but the chances of him making it into the top 100 a year later, as the Scot managed, appear unlikely given the degree to which the sport has moved on.
Murray believes the signs are good for the Londoner, though, and he added: "Having won the US juniors and being from the UK, he's going to get opportunities to play in some of bigger competitions, to see what the level's like and the sort of things he needs to work on.
"You've got to be patient. The reality is he hasn't made it yet, but he's made a good start. Winning a junior slam is a big thing to do.
"A lot of very good players have won them, even some great players, too. It's a good start but there's still a lot of hard work to do and a lot of matches to be won."
Success for Colin Fleming and Ross Hutchins in the doubles rubber Saturday would see Britain wrap up victory over Hungary and gain promotion back to Europe/Africa Zone Group I for the first time since 2009.
Captain Leon Smith said: "Ross and Colin are very professional and they'll go out very focused and will look to do a good job."
