As someone famous once said, "Know thy enemy". Here's all you'll need to know about the club that stands in the way of Pompey and the FA Cup.
Cardiff City: A Brief History
Cardiff were first known as Riverside AFC when they were formed in 1899 and originally played at Sophia Park before they changed their name to Cardiff City soon after King Edward VII granted Cardiff "City" status.
The club eventually moved to Ninian Park and joined the Southern League Second Division and started to make a name for themselves by progressing to the First Division.
The 1920's have been the club's most successful decade to date as they missed out on the First Division title to Huddersfield Town by goal average in 1924. The following year they would participate in their first FA Cup Final which they lost 1-0 to Sheffield United.
However, 1927 saw Cardiff lift their only major silverware to date as they beat Arsenal 1-0 at Wembley thanks to a goal by City legend Hughie Ferguson, aided by a goalkeeping error.
The following years saw the Bluebirds be relegated a couple of times and have their main stand destroyed by a fire but on the flipside they qualified for the Cup Winners' Cup numerous times thanks to winning the Welsh Cup.
After spending most of their recent history in the bottom two divisions, Cardiff were promoted to the old Division One (Championship) the same year Pompey were promoted to the Premiership (2003) after beating QPR in the Division Two Play-Off Final.
Dave Jones became the manager of the club in 2005 and the much maligned Peter Ridsdale led a consortium that bought the club from Sam Hammam in 2006 when Cardiff looked like Championship title contenders before falling away in 2007.
Winning at Wembley on Saturday would almost certainly be Cardiff's greatest achievement so we must do everything we can to stop this from happening and make sure the likes of Charlotte Church and Joe Calzaghe are frowning come Saturday night.
The Current Squad: Goalkeepers
Peter Enckelman
Cardiff's first choice Finnish 'keeper is on loan from Blackburn Rovers and will forever be known as "the guy who let in a goal from a throw in" after that embarrassing moment in the Birmingham derby. That is unless he picks up an FA Cup winners medal on Saturday.
Michael Oakes
Having spent most of his time at Wolverhampton Wanderers, Oakes joined Cardiff in the summer of 2007 and made eight appearances for the club before a suffering a blow to the face against QPR that saw Enckelman take his place.
The Current Squad: Defenders
Kevin McNaughton
The former Scottish PFA Player of the Year can play anywhere across the back four although predominantly features for Cardiff at right back. The 25-year-old is known for his silver haired image and was signed from Aberdeen in 2006. He scored his first goal for the club in the FA Cup and it was a belter - a 20 yard volley at Hereford United.
Tony Capaldi
The 26-year-old Norwegian born Nothern Ireland international plays at left back but can also play at left midfield if required. Capaldi is best known for his spell at Plymouth Argyle but left for Cardiff on a free at the end of the 2006/2007 season where he has had an inconsistent campaign according to some City fans.
Darren Purse
Purse arguably shouldn't even be playing in the Final after having his red card rescinded following a very nasty challenge on Andy Cole. Saying that, Cardiff fans reckon it'll be to Pompey's advantage if he plays as they don't rate him.
It seems like Purse has "Stefanovic syndrome" as he can still get into the side as club captain no matter how poor he is playing, although he may not play in the final due to the form of other centre backs in the squad.
Glenn Loovens
Known as "The Loovenator" by Cardiff fans, the imposing Dutch 6'2 centre back has previously played for Feyenoord before moving to Ninian Park where he forced Darren Purse out of the side after some strong performances. His battle with Kanu at Wembley could prove to be very interesting...
Roger Johnson
Johnson is making a name for himself at Cardiff and has been named their player of the season after some excellent performances at centre back. He's a fan favourite thanks to his commitment and his ability to score crucial goals, including the second at Middlesbrough in the FA Cup. Certainly one to keep an eye on at Wembley.
The Current Squad: Midfielders
Gavin Rae
The 30-year-old Scottish midfielder adds a bite to the midfield and is the most likely to match Muntari and Diop in the physicality stakes. Reminds me of Richard Hughes but he can pass the ball forwards.
Peter Whittingham
Whittingham has already scored against us once during his Villa days and scored the best goal in the FA Cup this season with his quick feet leading up to his amazing strike against Middlesbrough. The former England U-21 player is now 23 and is probably Cardiff's most under-rated player.
Stephen McPhail
The 28-year-old Irishman made his name at Leeds United before injuries scuppered his time at Elland Road and he moved to Barnsley before joining the Bluebirds. McPhail is back in the international side and has a very good pass on him so let's hope Diarra can keep tabs on him.
Paul Parry
Because of Cardiff's problems up front this season, Parry has had to play up front when he usually plays on the wing. "Porn Darry", as he is known on Pro Evolution Soccer, is a good dribbler and has an eye for goal much like our Niko Kranjcar.
Joe Ledley
Everyone knows who Joe Ledley is thanks to his impressive performances for club and country. At only 21 he has a big future and has the ability to play in the Premier League for sure, with Pompey one of many clubs rumoured to be interested in the jewel in Cardiff's crown.
Trevor Sinclair
The veteran midfielder has also had to play up front because of Cardiff's shortages in that area this season. Although he may not be good enough for the Premier League anymore the 35-year-old still has bags of experience that Dave Jones can call upon if needed.
Riccardo Scimica
Scimica is probably best known for his long spell at Nottingham Forest but I'm sure Pompey fans will remember him in that irritating Leicester City side that played in the Premiership when we were making our debut season there. Having only just come back from injury it's unlikely that we'll see too much of the 32-year-old at Wembley.
Aaron Ramsey
The 17-year-old is the youngest player to have ever played for Cardiff is already making a name for himself following some exciting and impressive performances this season. In fact, he has made such an impact that Harry Redknapp has tipped him to join one of the "big four" in the future whilst Alex Ferguson has already reportedly enquired about his services.
The Current Squad: Forwards
Jimmy Floyd Hasselbaink
He may be getting on at the age of 36 but there can be no denying the pedigree that Hasselbaink has. Barring a poor stint last season at Charlton which ended his career in the top flight, the veteran has scored goals wherever he has gone and whilst he isn't blessed with the pace he once had, it would be extremely foolish for any of our defenders to take their eye off him.
Robbie Fowler
Another man with a great goalscoring legacy in the Premier League, Fowler's transfer to Cardiff has been seen as a flop as he has spent most of the season injured. However, he should be fit to play in the final and with his footballing brain and quality finishing it would only take one chance for him to score and break Pompey hearts.
Steven Thompson
The 29-year-old Scot is likened to a battering ram because of his physical nature and his tenacity on the pitch. However, his scoring record isn't great and his relationship with Dave Jones has been strained this season.
Warren Feeney
A Northern Irish international that doesn't have a great goalscoring record and probably won't feature at Wembley at all.
The Manager
Ask any Pompey fan what they think of Dave Jones and most will instantly say "Scummer" but he doesn't have a bad CV. He started his managerial career at Stockport County and got them promoted to the old First Division before moving to the Scummers.
His time at The Dell came to an abrupt end following accusations of child abuse that turned out to be untrue but Jones bounced back by taking Wolves to the Premiership in the same year we were promoted.
However, they were relegated straight away and Jones was sacked after a poor run of form. He then replaced Lennie Lawrence at Cardiff and despite a good start, the form slipped again and there were reports claiming that Jones was on the verge of being sacked again.
However, he turned the clubs fortunes around and after guiding the Bluebirds to another safe mid-table finish, he is only one game away from the club's greatest achievement.
