The midfielder is one of a number of talented individuals who have gone on to play at a higher level after spending time working under the Athletic gaffer.
Moxon returned to the Galabank turf on Friday night wearing the blue of Carlisle United. He and his teammates left it late to secure a 2-1 victory over a well-drilled Annan team.
Murphy said: “It was brilliant for Paul Simpson and Carlisle United to come up.
“I thought my players were excellent and I think that sets us up for the cup games coming up.
“We didn’t have the luxury to be able to change our full 11, so we got tired later on.
“But it’s a pre-season exercise for us to get minutes under the belts of players.”
Murphy was a player under the watchful eye of Paul Simpson back in the Carlisle managers previous spell in charge.
He added: “I haven’t really leaned on him (Paul Simpson) for advice, more for players!
“Even tonight you see the likes of Max Kilsby, who started the first half, I was trying to see what their plans are for him.
“But I think it’s so early for Carlisle United that I don’t think any players will be coming out yet.
“When he (Paul Simpson) signed his contract, I was in his office the next day saying — there is a player I think you need to look at. It was Owen Moxon, because I knew I was going to lose him anyway.
“He’s gone there and done really well, so it’s a good advert for us.
“I think it is (a selling point). There’s a few players that have come here, developed and moved on.
“Like you’ve seen with Owen Moxon, there’s a way to get into the English league’s as well which I’m sure a lot of Scottish players would like to do.
“Hopefully we can do that with a few more players.”
