Murphy, the star of Norwich's FA Youth Cup win last season, put the equaliser on a plate for Scotland star Robert Snodgrass five minutes later.
Murphy said: "It was great. But I'm always pretty confident, it's the sort of person I am. I wasn't scared, just nervous.
"I like to get on the ball and really go at people, so that's what I did. Get shots off and crosses in and just play my game.
"It was a weird feeling, though, when I realised I was playing against men now, not kids. I knew I had to put a shift in.
"But as soon as I got my second wind I was fine. We didn't get the win we wanted, but we didn't get knocked out. So the lads are happy."
