Facundo Pellistri netted his second goal in Manchester United colours while Ole Gunnar Solskjaer's first team were being dumped out of the Champions League.
Pellistri, signed from Uruguayan side Penarol for around £9million on deadline day in October, scored for United's Under-21s in a battling 3-2 defeat by Accrington Stanley on Tuesday night. Anthony Elanga was also on the scoresheet, while Teden Mengi, Hannibal Mejbri and Ethan Galbraith were also among those to start for Neil Wood's side.
United's youngsters were competing in the knockout stages of the Papa John's Trophy against the League One side, having come through a group that included Morecambe, Salford City and Rochdale.
Cameron Burgess' header put Stanley in front early on, before Pellistri — who recently impressed with a goal for the Under-23s against Southampton — slotted home after a mix-up in the hosts' defence.
United then took the lead through Elanga, before a late double from Joe Pritchard swung the game in favour of Accrington, who currently sit in seventh place in League One.
Pellistri's goal represents his first against senior opposition and will no doubt have sent a message back to Solskjaer.
The 18-year-old could feature in United's upcoming Carabao Cup quarter-final against Everton on December 23rd.
Wood recently told MEN Sport how Pellistri was developing at United. "He's still settling in," he said.
"He's been training with us this week and it has probably helped him being out on the pitch because he's got a better relationship with the players on the pitch and he understands their game more because he's training more with them. That can only help him.
"He is progressing nicely but I don't want to put too much pressure on him. He is working hard, trying to take in as much information as he can."
United: Woolston; Fernandez, Fish, Mengi, Devine; Puigmal (Hugill 45+1'), Hannibal, Galbraith; Pellistri (Helm 78'), Shoretire, Elanga.
