Pedri 18, was among the ten players nominated for the award alongside Mason Greenwood, Bukayo Saka, Jude Bellington and others.
He joins the rank of Kylian Mbappe and Matthijs De Ligt who have won the award during 2018, 2019 respectively. There was no Kopa 2020 due to the coronavirus.
A memorable debut campaign at Camp Nou delivered 52 appearances, four goals and Copa del Rey glory.
Pedri also broke in the senior Spain squad, allowing him to make history at Euro 2020, before then going on to grace a gold medal match with his country at the Olympic Games in Tokyo.
Those exploits helped him to the coveted Golden Boy award, while he also finished fourth on the GOAL NXGN list for 2021 and landed himself a new contract at Camp Nou with a €1 billion (£846m/$1.13bn) release clause.
