Impressive Norwich City youngster Cameron King struck a brace in front of the watching Neil Adams to inspire the Canaries to a televised 3-1 U21 Premier League development win on Tuesday night at Carrow Road.

The likes of Gary Hooper, Ignasi Miquel and captain Elliott Bennett all played the full 90 minutes for stand-in development boss Jerry Gill, but it was the elegant teenager who caught the eye against Ugo Ehiogu's Tottenham U21s.

Carlton Morris' fourth minute header was deflected past Luke McGee by Spurs' defender Conor Ogilvie, before King reacted quickest to McGee's parry from Morris' close range strike to head a second before the interval.

Spurs hit back through Cristian Ceballos' superb shot past Declan Rudd but King fittingly sealed the win with a composed right-footed finish in the 70th minute before departing in the closing stages to a rousing reception from a national development league record attendance of 10.405 at Carrow Road.

Summer signing Conor McGrandles was also included but there was no place for Belgian international Vadis Odjidja-Ofoe, who featured in last week's behind-closed-doors win at West Ham.

Morris who was eligible to play for his parent club despite being on loan at League Two Oxford United and the bustling striker made his presence felt when he powered home Harry Toffolo's cross from Reece Hall-Johnson's diagonal pass with the aid of a fortunate deflection.

Tottenham looked to press forward with the influential Josh Onomah probing from central midfield but Rudd was able to watch his right-footed curler from 25 yards drift wide in the 15th minute.

Morris showed his intent at the opposite end when he rolled Ceballos but McGee batted behind the right-footed strike at his near post.

McGrandles then coaxed an exquisite pass into the path of the overlapping Miquel only for the Spaniard to be ushered out of play.

Hall-Johnson's spirit of adventure carved out another home chance but King hammered his close range shot against Christian Maghoma before the late arriving Toffolo drew a fine two-handed parry from McGee.

Emmanuel Sonupe spurned the visitors' best chance to date in the 23rd minute with a fine burst through the centre of the park to collect Daniel Akindayini's pass but his finish was woefully off target from 18 yards.

Morris' bicycle kick was collected by McGee with the game increasingly stretched.

Hooper used his experience to fend off Maghoma and service McGrandles but Morris' strike was deflected behind.

The graceful King fed Toffolo again in the 35th minute but Ogilvie's positioning was sound to clear the danger with Hooper lurking.

Hooper's despairing dive failed to connect with Morris' cross down the left but City were rewarded for their persistence when King headed home from point blank range after McGee could only parry Morris' initial near post strike from Hall-Johnson's cross.

McGee then denied King with a superb one-handed low stop as Gill's rampant side surged forward again.

Ceballos went close to reducing the arrears in the final seconds of the opening period with a slaloming run and strike on his left foot that veered just wide of Rudd's left-hand post.

City captain Bennett was cautioned for hauling down Sonupe but Ruben Lameiras' floated free kick sailed behind in the final act of the half.

Miquel's impudent long range lob five minutes after the restart nearly embarrassed McGee after the Spurs' stopper had race from his line.

Ceballos had already served notice of his prowess from distance and it was the Tottenham midfielder who dragged Spurs back into the contest in the 56th minute with a thumping left-footed strike from 20 yards that flew past Rudd.

Hooper was upended by Maghoma as City looked to break out on the counter, which earned the Spurs; centre back a yellow card before McGrandles was forced to take evasive action at the cost of a booking to halt the flying Sonupe.

The cool King restored Norwich's two-goal lead in the 70th minute with a composed right-footed finish 16 yards out into McGee's bottom corner from Morris' excellent cut-back.

Spurs' continued to press and it needed Rudd to produce an excellent one-handed stop to deny Joe Pritchard at the far post. The City keeper then produced an even better stop to foil Onomah from a 20-yard free kick.
