Newcastle's youngsters conceded three times in the opening 45 minutes at the Lotus Training Centre, trailing inside four minutes through Tyrese Omotoye's opener before strikes from Abu Kamara and Tom Dickson-Peters extended the Canaries' advantage before the half-time whistle, with United goalkeeper Jude Smith - making his Magpies debut at under-21 level since joining from East Fife, saving the latter's penalty on the half-hour mark.

Dylan Stephenson, who made his Magpies first-team debut against Athletic Club last month, reduced the deficit for United's second-string within 60 seconds of the restart before City regained their three-goal cushion following Jaden Warner's strike.

Jay Turner-Cooke gave the young Magpies hope after scoring from the penalty spot, with Norwich defender Sean Stewart receiving a red card in the build-up, but the visitors were unable to spark a fightback in Norfolk. 

In the 4th minute, Norwich opened the scoring as Omotoye controlled Dickson-Peters' pass inside the penalty area before firing a left-footed effort into the bottom right-hand corner.

Smith was on hand to deny Dickson-Peters from the penalty spot, with the Scottish teenager - who began his career at Celtic's Academy - getting down low to save the striker's spot-kick.

However, the hosts doubled their advantage as Kamara, from a tight angle, fired the ball into the far right-hand corner. 

On the stroke of half-time, Dickson-Peters netted City's third of the afternoon after placing the ball into the right-hand corner.

Newcastle began the second-half in bright fashion as Stephenson, who scored 12 Premier League 2 goals last term, netted his first goal of the 2022/23 campaign with a close-range finish.

In the 55th minute, Norwich added a fourth as Warner guided a header, from Joe Duffy's teasing cross, into the top right-hand corner.

In the 70th minute, Newcastle pulled a goal back as Turner-Cooke netted from 12 yards. After Niall Brookwell's header towards goal was blocked by Stewart, with the City full-back receiving a red card, the 18-year-old attacking midfielder converted his spot-kick after firing into the middle of the net.
