His debut for the club came in a 3–0 win over Blackburn Rovers on 11 September 2004. In the 2005–06 season, N'Zogbia established himself as a first-team regular, appearing in 41 matches. He scored Newcastle's first goal of the season in the 1–1 draw at home to Fulham, with a skilful free kick. He further displayed his goalscoring ability with 6 goals in total that season, including a solo effort in the 4–1 win over fierce rivals Sunderland. He was the fourth highest goal scorer for Newcastle in the 2005–06 season and also contributed seven assists. This good form attracted interest from clubs such as Arsenal but he instead signed a three-year contract extension with Newcastle at the end of the season.
