CNN —It took teenager Marc Guiu just 23 seconds to make history for Barcelona as he scored on his debut in the team’s 1-0 win against Athletic Bilbao. Guiu was brought on as a second-half substitute and made an instant impact, put through on goal by João Félix before firing a shot past Unai Simón. At the age of 17 years and 291 days, it made him the youngest player to score on debut for Barcelona. I’m just enjoying the moment, I’m still flying,” Guiu said after the match. Sixteen-year-old Lamine Yamal has also made a big impression this year, becoming the youngest player to appear in a competitive fixture for Barcelona in April and scoring his first league goal earlier this month.
