Eighteen months have now passed since Matt Ritchie left the Magpies, but Murphy has not forgotten the impact his fellow winger had on his career at St James' Park.
Murphy was by no means an immediate success after joining Newcastle from Norwich in 2017 and headed out on loan to the the Championship.
But Ritchie always had faith in Murphy and was a huge help during his challenging early days at the club.
Not only has Murphy now long established himself as a key player for Newcastle on the pitch, he's an influential figure behind the scenes and was recently added to the leadership group by Eddie Howe.
"It feels amazing to have the leadership role," said the 30-year-old, who is set to be in the starting XI for tonight's Champions league tie against Qarabag.
"I've had some really good mentors over the years.
"Matt Ritchie is one. He was amazing for me and I sort of took a lot from him.
"He was one of the first people I reached out to when I got elected into the leadership group and he said he had sensed those qualities in me from early on. It was a good achievement for me."

There's a lot of talk of leadership groups in football but what does being part of one actually entail?
Murphy, who is joined by Bruno Guimaraes, Kieran Trippier, Dan Burn and Nick Pope in Newcastle's, said: "We have a WhatsApp group. We talk on there, we put messages in there before games about things we want to make people aware of in the build-up to games.
"Within the leadership group everyone has different qualities.
"For myself, as you can tell from my voice I'm not the loudest shouter. I like to lead by example with my output, show people what it's like to do the right things. The group is really good at following suit.
"Burny leads by example with the voice and action, Tripps leads by example, Bruno speaks for himself. You can see with his performances what sort of leader he is and how inspiring he is.
"And Nick Pope is really strong with his voice and presence. Everyone has unique things they bring in the dressing room, behind closed doors."
Former captain Jamaal Lascelles was also obviously a key figure in the leadership group before his January exit.
Murphy said: "Jam was a big figure. He looked after everyone really well. He won't mind me saying he was the aggressive one. You need that in your team every now and then.
"With him it was all about total respect. He could really lead the dressing room like that.
"We lose that aggression but we have different ways of navigating that and making sure we go into every game fit and firing.
"We spoke a lot recently about one brain, everyone on the pitch thinking together, being a collective, doing everything together, pressing together, sitting off together.
"Everything is done using one brain. That's been really clear to see in the last four games. We have to keep improving on that."
Murphy scored his first Champions League goal for Newcastle in last week's 6-1 dismantling of Qarabag in the first leg, before making his 250th appearance for the Magpies in the weekend defeat at Manchester City.
He's come an awful long way since those early days at Newcastle and his loan stints in the Championship.
Asked whether he could have ever envisaged his Newcastle career playing out like it has done in recent years, he said "At West Brom, no. When I went to Sheffield Wednesday yes, I could start seeing the resurgence.
"Everyone has a similar journey they want to go on, there are just different paths and that was my path.
"Luckily when I was on loan at Sheffield Wednesday it started to click for me.
"I came back and Jacob Murphy 2.0 kind of formed. I got a good couple of seasons under Steve Bruce then the gaffer came in and the rest is history."
