Kanu, 31, notched only his sixth goal of the season in only his 14th start to put Pompey in their first final since 1939, but Redknapp confirmed: "He has earned an extra year on his contract by playing in 25 games and on the strength of that today I'd certainly give him that."

Redknapp admitted his side struggled to get the better of Championship promotion-chasers Albion but said: "Once we had gone in front I felt fairly comfortable because I know it takes something special to beat (goalkeeper) David James.

"With Jermain Defoe cup-tied I haven't got a prolific scorer and it was a concern where the goals were going to come from.

"Kanu certainly hasn't scored many lately but we changed things a bit at half-time, pushed him up and brought in Niko Kranjcar and Papa Diop from the flanks to play a bit narrower."
