Portsmouth have made it through to the FA Cup final after seeing off Championship rivals West Brom at Wembley.
A second half goal from Kanu was good enough to send Harry Redknapp to his first final as a manager and also the first final for Pompey for 69 years.
The former West Brom striker side-footed an easy chance to see off the Baggies after Dean Kiely had denied Milan Baros and Zoltan Gera had failed to clear.
Baros, who looked to have handled in the build-up to the goal, missed a simple chance to seal the win.
Portsmouth were almost made to pay but Robert Koren’s shot hit the bar and Ishmael Miller fired wide late on.
