The Nigerian set up the winner for Kanu in Pompey's FA Cup triumph of two years ago and has his sights set on more Wembley glory this season.

A lot of murky water has passed under the bridge since that famous win over Cardiff, however, with Portsmouth now in administration and facing almost certain relegation from the Barclays Premier League after a sustained period of financial mismanagement at the club.

Portsmouth's long-suffering fans have been forced to endure much in recent times, but Utaka is optimistic he and his team-mates can deliver some cheer before the season's end.

"We won at Wembley before and we're determined to go back there again," Utaka told www.portsmouthfc.co.uk.

"Winning the FA Cup was a fantastic achievement for us and we will try to repeat that this season.

"We're ready for anyone. Birmingham are a good side who have done very well this season.

"It will be a tough game - it always is in the FA Cup. It doesn't matter who you play, you're always going to be tested."

Birmingham striker James McFadden is battling to be fit for the game at Fratton Park.

McFadden was substituted during last weekend's league win over Wigan with a groin injury after scoring the decisive goal from the penalty spot.

He joined up with Scotland after the weekend but was forced to withdraw from the side to face the Czech Republic on Wednesday night - the first game of the Craig Levein era.

Blues boss Alex McLeish said: "When he ran off willingly last week I said 'it's not like McFadden' and I seriously worried about his chances of playing for Scotland.

"Craig Levein was brilliant. He was up front in terms of the medical side of things.

"We contacted the Scotland doctor and Craig who said he wouldn't take any chances if James wasn't 100% fit.

"Now I'm hoping he wasn't far away from playing but we will assess him in training to see whether he is available to play in the Portsmouth game."

Tomorrow's other last-eight tie pits Fulham against London rivals Tottenham at Craven Cottage.

Spurs are flying high in the Premier League and are coming off the back of a solid win over Everton last weekend, and boss Harry Redknapp concedes he is enjoying presiding over an impressive campaign.

"We've got to keep going," Redknapp told www.tottenhamhotspur.com.

"We're up there and it's a great position to be in.

"The most important thing is the way we play and the way we played in the first half against Everton, the football we played, the way we passed the ball, the way we moved the ball, our movement off the ball, it was fantastic.

"I enjoy that and I enjoy managing a team that plays like that. That will always been important to me."

Fulham boss Roy Hodgson is again guiding Fulham to a stellar campaign, with his side comfortably inside the top 10 in the Premier League and into the last 16 of the Europa League, where Juventus are their next opponents.

Victory tomorrow would see Fulham reach Wembley for the first time since the FA Cup final in 1975.
