• Marc Guiu had a night to remember on Sunday, October 22
• He scored Barcelona's game-winner against Athletic Bilbao
• The La Masia graduate still follows some strict rules that the academy implements

Marc Guiu needed 23 seconds to announce himself to the world on Sunday. With a severely undermanned Barcelona struggling to break down a resolute Athletic Bilbao, the 17-year-old stepped up and provided the winning goal late in the game.

He is the latest player in a list of La Masia graduates to make their mark on the Barcelona first team. Despite all the fame and popularity that comes with scoring for Barcelona at a young age, there are rules he must follow.

Xavi Hernandez's team is going through an injury crisis at the moment. Key players Pedri, Frenkie de Jong, Robert Lewandowski, Jules Kounde, Raphinha, and Sergi Roberto did not play in Sunday's match.
