Liam Delap said there was "no better feeling" after marking his senior debut with a goal as defending champions Manchester City beat Bournemouth in the Carabao Cup third round.
The 17-year-old forward struck in the first half, latching on to Phil Foden's fine ball before placing a composed finish beyond the goalkeeper.
Sam Surridge equalised but Foden stabbed in the winner late on.
"Since I was a boy all I dreamed of was playing senior football," Delap said.
"To make my debut tonight and get a goal, there is no better feeling to be honest.
