Mahdi Nicoll-Jazuli became Chelsea’s youngest-ever Premier League player last week and the second 16-year-old to make his senior debut already this season. Here we look at the rest of the Blues’ all-time list of youngest players.
Nicoll-Jazuli and Reggie Watson were both involved for Xabi Alonso’s team during pre-season before being handed their competitive debuts by our Spanish manager in the last couple of weeks.
Those two Academy midfielders became the eighth and ninth 16-year-olds to have appeared for Chelsea’s senior team in competitive action. This is the full list…
Ian Hamilton – 16 years 138 days
Ian 'Chico' Hamilton remains our youngest ever player. While still a junior, he was handed his senior debut in a league game against Tottenham at White Hart Lane in March 1967, and headed the Chelsea goal in a 1-1 draw. It was the first of five appearances Hamilton made for the Blues.
