The defender, who Alan Pardew has been raving about since pre-season, came off the bench at St James’s Park on Saturday to make a thrilling contribution at both ends of the pitch.
The 22-year-old – sent on after Mapou Yanga-Mbiwa’s dismissal for pulling down Luis Suarez – put Newcastle 2-1 ahead getting on the end of a Yohan Cabaye free-kick, before playing a major part in Pardew’s ripped apart defence.
Ripped apart through injury and Yanga-Mbiwa’s red card - certainly not by a Liverpool side who were second best in most departments the entire match.
Dummett signed a one-year deal at United in the summer after returning from a successful loan spell at St Mirren.
But now there have been preliminary discussions over a new long-term contract for the Wales Under-21 international in recognition for the progress he has made so far this season.
Paul Dummett: “It is another step – I just need to keep going.
“It’s only just starting. I’ve done nothing yet in football. This is my only second Premier League game of my career, and I just need to keep my feet on the ground and working hard for the club.
“I have to give credit to Mike Williamson.
“He was the one who sent me round the back, and he should claim an assist for that goal! It was a good finish though, and I’m happy.
“When I scored I didn’t know where to run.
"All of the fans came running down the Gallowgate End – it was crazy. It’s something I’ve never experienced before and might never again.
“You have to cherish these moments. I’d scored two for St Mirren, but nothing is like scoring in front of 50,000 Geordie fans.
“That’s something I’ve dreamt of all my career.
“I actually dreamt about scoring the night before, so this really is a dream come true. Maybe I should dream about it more often!
“Hopefully, I’ll score more that way. To score, and get one at the Gallowgate End, just makes it even better.
“I was desperate to get on and play a part, but nervous at the same time.
“To play against (Daniel) Sturridge and Suarez at centre back, which isn’t my normal position, was nerve racking for me.
“We had to show we were a team out there, and show we could get a result. Every player worked hard as a team and showed togetherness.
“I’ll go out and give the manager a headache.
“Hopefully, I’m involved because it is such a big game.”
