Paris Saint-Germain

Bruno Ngotty scored the winning goal which defeated Austrian club Rapid Wien in the 1996 UEFA Cup Winners' Cup Final, giving Paris Saint-Germain their only cup triumph in the tournament. He was also included in the squad that reached the final again the next year, losing to Barcelona 1–0 at Feyenoord Stadion.^{[citation needed]}

A.C. Milan

Ngotty 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.^{[citation needed]}

Marseille

After his relatively short spell at 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.^{[citation needed]}

Bolton Wanderers

Ngotty 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.^[6][7]

In January 2002, this move became permanent, Ngotty 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,^[8] but with manager Sam Allardyce wanting to reduce the average age of the squad, Ngotty was released at the end of his contract in May 2006.^{[citation needed]}

Birmingham City

Ngotty 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^[9] and Newcastle in the FA Cup.^[10]

When Nigel Pearson replaced Ian Holloway as the club's new manager, Ngotty 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, Ngotty joined Hereford United on loan for a month.^[16] Making his debut in Hereford's 1–0 defeat to Leeds United.^[17] The loan was extended for a further month on 25 October.^[18] However it was cut short after Ngotty suffered a serious injury in a match against Peterborough United, leaving the field after nine minutes with a suspected ruptured Achilles.^[19] On 29 May 2009, Ngotty was released at the end of his contract.^[20]
