The number uniform Eden Hazard wore for Chelsea in 2013 was 17. Hazard joined Chelsea from French club Lille in 2012 and initially wore the No. 17 shirt, which he kept through the 2012–13 and 2013–14 seasons.
The number became closely associated with Hazard during his early Chelsea career. In the 2012–13 season, he helped Chelsea win the UEFA Europa League, and in the 2013–14 campaign he was one of the club’s most influential attacking players. He generally operated from the left side but was also given freedom to move centrally.
Hazard later changed to Chelsea’s No. 10 shirt before the 2014–15 season. That switch can cause confusion in trivia questions, because No. 10 became his better-known Chelsea number. Juan Mata had previously worn No. 10, while Hazard’s first Chelsea shirt number was 17.
