Micah Hamilton and Oscar Bobb scored their first goals for Manchester City in a 3-2 win over Red Star Belgrade on Wednesday, completing the club's perfect Champions League group stage.
The defending champions had already qualified for the knockout stages as Group G winners, giving Pep Guardiola the luxury of making nine changes.
Bobb and Hamilton were two of the young players given the opportunity to shine on European football's biggest stage, and they relished the opportunity.
In 2017, a photo of Hamilton receiving instructions from Guardiola as a ball boy went viral ahead of kickoff.

In 19 minutes, he rewarded his manager's faith in him by firing high past Omri Glazer from a narrow-angle.
Bobb has played a larger role in first-team squads this season, and his solo run and cool finish doubled City's lead early in the second half.
Red Star had nothing to play for except pride, as they were guaranteed to finish last in their section before the game began.
Hwang In-beam pulled a goal back for the Serbian champions.
But Hamilton was impressed once more as he won a penalty, and Kalvin Phillips stepped up to score his first City goal five minutes later.
Aleksandar Katai struck for Red Star in stoppage time, but City became the second English side to win all six Champions League group games after Liverpool in 2021/22.
