Answer
Sinisa Mihajlovic, the Serbian manager, brought Gianluigi Donnarumma into AC Milan's first team. Mihajlovic recognized the young goalkeeper's talent and potential and gave him his professional debut in October 2015 at just 16 years old. Donnarumma quickly established himself as the Rossoneri's first-choice goalkeeper, impressing with his shot-stopping abilities and commanding presence in goal.
