David Philippe Henri Ngog[2] was born on 1 April 1989[3] in Gennevilliers, Hauts-de-Seine,[4] to a Cameroonian father and a French mother.

[9] Ngog made his first start for Liverpool on 7 February 2009 against Portsmouth, and scored his first league goal on 3 March 2009 against Sunderland in a 2–0 win at Anfield.

On 25 October, in a crucial game against Manchester United, he came on for goalscorer Torres at Anfield, scoring a goal in the 96th minute in the 2–0 win to seal an important victory for Liverpool.

He scored his fourth goal of the season on 9 November against Birmingham City before winning a controversial penalty[14] that gave Liverpool a draw after Steven Gerrard converted from the spot.

[16] Benítez showed his faith in Ngog by handing him a start against Everton in the Merseyside derby; this match finished 2–0 to Liverpool.

[18] Ngog's goal nine minutes from time eventually broke the resistance of a determined Unirea Urziceni at Anfield in the Europa League.

[19] On 29 July, Ngog scored twice in Roy Hodgson's first competitive match as manager in Liverpool's Europa League third qualifying round first leg 2–0 win over Macedonian side Rabotnički.

After being left out of the game against Birmingham City, Ngog shot to fire again in the Europa League, scoring two in Liverpool's 4–1 victory over Steaua București.

He continued to be an impact sub from the bench, following the departure of Torres, and the signings of Luis Suárez and Andy Carroll and often finding himself in the starting line-up.

[citation needed] On 31 August 2011, for a £4 million transfer fee, Liverpool announced that Ngog had completed a move to Bolton Wanderers in a three-year deal.

[28] On 27 January 2014, Ngog joined Premier League club Swansea City until the end of the season, signing for an undisclosed fee.

[30] On 1 September 2014, Ngog ended his six-year spell in the English leagues after signing a two-year contract with Ligue 1 outfit Reims.

When asked why, Cameroon coach Paul Le Guen said that Ngog had insisted on a starting spot with the Indomitable Lions.
