Argentine striker Alejo Veliz came off the bench for Tottenham Under-21s in their 5-0 EFL Trophy win at Colchester.
The 20-year-old under-20 international joined Spurs from Rosario Central last month in a deal said to be worth £13m.
He got his first taste of English football having replaced Will Lankshear after 62 minutes in Essex.
Spurs cruised to an opening win in Group L thanks to doubles from Jamie Donley and Jude Soonsup-Bell and another from Lankshear.
Elsewhere there were wins for Liverpool, Aston Villa and West Ham’s youngsters while Everton, Fulham and Crystal Palace’s sides tasted defeat.
Records tumbled at St James Park as Reading romped to a 9-0 win at injury-hit League One rivals Exeter in Group O – the Grecians’ joint-worst ever defeat and the Royals’ biggest win in 122 years.
Tom McIntyre took just three minutes to put the visitors ahead and a Zak Jules own-goal doubled the advantage just after the half-hour.

It was not until 56 minutes that Paul Mukairu grabbed a brace inside four minutes and Dom Ballard, Ben Elliot, Taylan Harris, Caylan Vickers and Ballard again completed the rout in the closing stages.
Wigan come from behind to stun Leicester
Leicester’s youngsters were also on the end of a big defeat having taken the lead at Wigan in Group D.
Arjan Raikhy’s powerful opener for the Foxes on 30 minutes was cancelled out within four minutes by a penalty from Latics striker Josh Magennis after a foul on debutant Liam Shaw.
Magennis turned the tie on its head within seconds of the turnaround and Wigan ran riot with Callum Lang, a Brad Young own-goal, Harry McHugh, Chris Sze and Josh Stones completing a 7-1 thrashing.
Meanwhile, Liverpool’s Under-21s saw-off Morecambe with ease in Group A.
Mateusz Musialowski put the Reds ahead on 13 minutes with a deflected effort and Calum Scanlon slotted the second just before the half-hour with first-team prospect Bobby Clark getting the third with another deflected shot before the interval.
West Ham left it late to deny Bristol Rovers a second Group P win, however.
Sam Finley had put Gas ahead midway through the first half but Callum Marshall levelled from the spot 20 minutes from time and George Earthy turned the tie around 12 minutes from time while Marshall’s second sealed it in stoppage time.
