Lille

Hazard joined Lille in 2005 and spent two years developing in the club's local sports school, due to its youth academy in Luchin not being in operation at that time.^[30] On 28 May 2007, he signed his first professional contract agreeing to a three year deal with Lille.^[29] At the start of the 2007–08 season, at the age of 16, Hazard was promoted to the club's reserve team in the Championnat de France amateur, the fourth level of French football, though he still played with Lille's under-18 team in its league and the Coupe Gambardella. Hazard made his amateur debut on 1 September 2007 in a league match against Racing Club de France appearing as a second half substitute in a 3–1 defeat.^[31] He made his first start a week later in the team's 1–0 defeat to Lesquin.^[32]
After spending the majority of October and the early part of November playing with the club's under-18 team, on 14 November, due to several players being on international duty, Hazard was called up to the senior team by manager Claude Puel to participate in a friendly match against Belgian club Bruges on 16 November.^[33] He appeared as a substitute in the match and, as a result of his performance, was included in the 18-man squad to face Nancy in a league match on 24 November.^[34] Hazard, subsequently, made his professional debut in the match coming on as a substitute in the 78th minute.^[35]
Hazard returned to the club's reserve team and spent December playing with the squad. Following the winter break, Hazard returned to the first team in January and made substitute appearances in three league matches against Metz, Sochaux, and Paris Saint-Germain.^[36][37][38] Following the match against Paris Saint-Germain, he was demoted back to amateur level where he played concurrently with the reserve team in the fourth division and the under-18 team in the Coupe Gambardella. On 17 May 2008, he scored his first amateur goal in a 3–2 victory over Vitré.^[39] Hazard finished his amateur career with 11 appearances and one goal, helping the reserve team finished in fifth place, which was first among professional clubs' reserve teams playing in the group.
