Another teenager has made history for Barcelona in the Spanish league. Seventeen-year-old Marc Guiu scored about 30 seconds into his first-team debut to give the Catalan club a 1-0 win over Athletic Bilbao on Sunday, becoming the second-youngest player this century to score in his league debut. “They told me to go out there and give everything I have, that I would have my chances,” Guiu said. “I dreamed about this so many times. I won’t sleep tonight.”
