At just 16-years-old, Gianluigi Donnarumma is not your average teenager, he’s already turning out for 18-time champions AC Milan in the Italian Serie A. The youngster had played for Milan in pre-season, including in a friendly against Real Madrid, but this was his first competitive action for the Italian champions, and in the process he became the youngest goalkeeper in Serie A history, with Gianluigi Buffon only making his debut at the age of 17. Wishing him a long and successful career.
