N'Gotty started his career with Olympique Lyonnais from the opening of the 1988–89 season to the close of the 1994–95 season. N'Gotty managed to play 143 league games scoring 10 goals during his time at Lyon.
N'Gotty was part of the A.C. Milan team that won the Serie A title in 1999, making 25 league appearances for the club. He played alongside the likes of Paolo Maldini during his time there. He was sent on loan to Venezia during 1999 where he played 16 matches.
Marseille
After his relatively short spell at A.C. Milan he returned to France with Olympique Marseille. This turned out to be an even shorter spell than his stay in Milan which lasted for one season. He managed to play in 31 games during his only season at the club.
Bolton Wanderers
N'Gotty originally rejected Bolton Wanderers' loan offer, but later agreed to spend the rest of the season with the club. The move eventually became a permanent deal. He made his Bolton debut against Blackburn Rovers, in a match which finished in a 1–1 draw, on 19 September 2001. He scored his debut goal for the club seven months later, his only goal of the season coming in a 3–1 defeat at Everton. In January 2002, this move became permanent, N'Gotty being cited as one of the prime chances for Bolton success. His first full season for the club started in unfortunate style, as he received two yellow cards and one red card in his first six games. After this rather disappointing start he became a regular part of the first team and was voted supporters player of the year for the 2005 season. He originally wanted to end his career at the Reebok Stadium, but with manager Sam Allardyce wanting to reduce the average age of the squad, N'Gotty was released at the end of his contract in May 2006.
Birmingham City
N'Gotty was signed by Birmingham City on a one-year deal on 6 July. The team achieved promotion to the Premier League that same season, finishing as runners up. He decided not to take up the option of another year at Birmingham. He scored two goals during his stay at Birmingham, against QPR in the league and Newcastle in the FA Cup.
Leicester City
On 4 June 2007, N'Gotty moved to Leicester City on a free transfer, signing a two-year contract. Chairman Milan Mandarić revealed on 27 September that N'Gotty was signed by him, and not then-manager Martin Allen, during a face-to-face meeting with the club's fans. N'Gotty was named in the Championship Team of the Week following the club's 1–1 draw against Stoke City on 29 September, together with teammate Márton Fülöp. He played his 500th competitive game in an M69 Derby on 12 January 2008, in which Leicester won 2–0. N'Gotty played a total of 38 league games as Leicester were relegated from the Championship. When Nigel Pearson replaced Ian Holloway as the club's new manager, N'Gotty played in only one pre-season game and was neither in the squad's tour of Slovenia nor the opening match of the season. On 25 September 2008, N'Gotty joined Hereford United on loan for a month. Making his debut in Hereford's 1–0 defeat to Leeds United. The loan was extended for a further month on 25 October. However it was cut short after N'Gotty suffered a serious injury in a match against Peterborough United, leaving the field after nine minutes with a suspected ruptured Achilles. On 29 May 2009, N'Gotty was released at the end of his contract. In January 2011 N'Gotty joined French 6th-tier side l'AS Lattes.
International career
Though many observers predicted that N'Gotty's international career was to be successful, he made only 6 appearances with Les Bleus, making his debut on 17 August 1994 against Czech Republic alongside Zinedine Zidane and Lilian Thuram, but while the two were soon able to secure a place in the national team, N'Gotty failed to impress Aimé Jacquet and played only 5 more matches until 1997, never being called up for a major event.
