Manchester City youngster Cole Palmer scored on his Champions League debut within minutes of coming on as a substitute and fans have taken to social media to warn rival fans this is just the start.
Palmer scored his first goal as a professional last month in the Carabao Cup and has made a handful of appearances off the bench so far this season.
On Saturday he came on in the final minute of the game in the Premier League against Burnley before turning out for the Under-23s the same evening.
Being handed his first taste of European football against Club Brugge on Tuesday night, Palmer needed minutes to find the back of the net in the 5-1 win in Belgium.
