On May 17, 2008, Pompey celebrated FA Cup glory after a 1-0 win against Cardiff at Wembley.
Kanu’s first-half effort earned the Blues success in the competition for the first time since 1939.
The Nigerian scrambled home the only goal of the game at the near post eight minutes before half-time, after Cardiff keeper Peter Enckelman fumbled John Utaka’s cross.
It was boss Harry Redknapp’s first major piece of silverware in his managerial career.
The success earned Pompey a place in the Uefa Cup – their first taste of European competition.
