Zambian teenager Miguel Changa Chaiwa came off the bench to feature against Manchester City in the UEFA Champions League.
Chaiwa was introduced in the 65th minute to replace Switzerland striker Cedric Itten to play the last 26 minutes.
The Swiss side Young Boys succumbed to a 3-0 loss at the hands of the defending Champions.
A brace from Erling Braut Haaland and a goal from Phil Foden was enough for the Citizens to cruise to their fourth win of the group stage.
The win means City have secured their place in Champions League knockout stages.
RB Leipzig saw off Red Star Belgrade 2-1 to also qualify to the knockout stage.
