Paul Jones (1) Born: May 29, 1973
Vastly experienced keeper with fond memories of the Millennium Stadium this season; Jones is a regular in Mark Hughes' Wales side and played in the 2-1 win over Italy.
He accompanied former manager Dave Jones from Stockport to Southampton in 1997, costing a then club record £1.7 million and won the club's Player of the Year award in his first season.
Jones was Saints' first-choice keeper for five seasons but has spent much of the current campaign on the bench.
At his best, he is an outstanding shot-stopper and outshone Peter Schmeichel in the last ever game at Maine Road. However, crosses can cause him problems and recent seasons have been blighted by inconsistency.
Antti Niemi (14) Born: May 31, 1972
Finnish international who has been a revelation since his £2 million move from Hearts at the start of the season.
Niemi's agility, excellent reflexes and consistency prompted tabloid suggestions he was a contender to replace Fabien Barthez at Manchester United; they also gave Southampton one of the Premiership's best defensive records.
Minor injuries have been the only problems the unflappable Niemi has experienced in his first season in England while his success has come of no surprise to Hearts fans, who still remember a 6-0 defeat to Rangers when the Finn was a unanimous choice as Man of the Match.
Jason Dodd (2) Born: November 2, 1970
Long-serving defender who has captained Southampton under Dave Jones, Glenn Hoddle, Stuart Gray and Gordon Strachan but is likely to miss the cup final with injury.
A former England Under 21 international, Dodd has played left back, centre back and in midfield for Southampton, though since the sale of Jeff Kenna to Blackburn in 1995, he has been the club's first-choice right back.
At his best, Dodd was notable for his reading of the game, leadership and long-range shooting but this season, hampered by injury problems and a lack of pace, he has lost his place to Paul Telfer.
Wayne Bridge (3) Born: August 5, 1980
The first Southampton player since Matt Le Tissier to play for England, Wayne Bridge comes from nearby Winchester.
He started out as a left winger and made his Saints debut on the opening day of the 1998-9 season but was converted to a left back by Dave Jones.
Bridge has improved defensively over the years and the pace on the ball, ability to beat an opponent and excellent crossing which he showed on the wing are hallmarks of his attacking approach to his defensive duties.
A member of England's 2002 World Cup squad, Bridge holds the record number of consecutive appearances in the Premiership for an outfield player and did not miss a game for three years.
Claus Lundekvam (5) Born: February 22, 1973
Norwegian international centre back who has proved a bargain buy since Graeme Souness paid £400,000 for him in 1996, though he has reached 250 appearances without a single goal.
An elegant player who used to stroll out of defence with the ball, Lundekvam has curbed his attacking instincts as he has become more consistent.
He is at his best alongside a dominant defender and has formed fine partnerships with Ken Monkou, Dean Richards, Paul Williams and now Michael Svensson in the centre of defence.
Paul Williams (6) Born: March 26, 1971
A former Derby player who followed Gordon Strachan from Coventry to Southampton, where he was a surprise free transfer signing.
A committed, if at times error-prone, centre back, he played an important role in Saints' resurgence under Strachan last season.
But distribution can be a weakness and he has been replaced by Svensson in the team this season. Will probably be a substitute in Cardiff.
Michael Svensson (11) Born: November 25, 1975
A member of Sweden's World Cup squad last year - though he did not play in the tournament - Svensson cost Southampton £2 million from French club Troyes.
Nicknamed 'Killer', Svensson's aerial strength complements Lundekvam's reading of the game and makes him a threat at set pieces.
He is a resilient central defender who has produced many of his best performances in rearguard actions.
Danny Higginbotham (19) Born: December 29, 1978
Former Manchester United defender who joined Southampton from Derby in January on loan, though a £1.5 million transfer will be completed this summer.
Derby's Player of the Year in the 2001-2 season, Higginbotham can play left-back but prefers a position in the centre of defence.
His only opportunities for Southampton have come at left back and Higginbotham, who has yet to make a real impact so far, will only start in the event of injuries.
Paul Telfer (33) Born: October 21, 1971
Another former Coventry player, Telfer was contemplating quitting football to go backpacking in Australia when Strachan lured him to Southampton on a free transfer.
Capped once by Scotland, Telfer has spent much of his career as a right-sided midfielder where his fitness, stamina and unselfishness stand him in good stead, though his crossing and goalscoring record leave something to be desired.
Telfer has been one of the most improved players in Saints' squad this year after being moved to right-back, though occasionally his positioning in defence can be suspect.
Chris Marsden (4) Born: January 3, 1969
With Dodd out, Chris Marsden will probably captain Southampton if he recovers from his own knee injury in time.
The 34-year-old had only played in the Premiership on loan until he signed for Saints, his eighth club, four years ago in an £800,000 move, but the combative midfielder has established himself as a first choice and a cult hero at St Mary's.
Marsden was a central midfielder before being moved to the left by Strachan, where he has forged a fine understanding with Wayne Bridge, and provides control with his excellent short passing game.
A deceptively good crosser, Marsden was Saints' Player of the Year last season and scored one of the most memorable goals of the campaign with a solo run against Ipswich which provoked comparisons with John Barnes' effort at the Maracana.
Matthew Oakley (8) Born: August 17, 1977
A one-club man who Strachan has suggested for the England squad, central midfielder Matthew Oakley will lead Southampton if both Dodd and Marsden do not play.
Initially a right-winger, Oakley flourished as an anchor midfielder under Glenn Hoddle where his astute reading of the game and excellent distribution were particular benefits.
Has not always been a crowd favourite, but under Strachan he has added an edge to his game and his leadership qualities have become more apparent. Oakley, who formed a fine partnership with Rory Delap in the centre of midfield, has the ability to score more goals after a disappointing, but important, two this year.
Anders Svensson (12) Born: July 17, 1976
Sweden's David Beckham, playmaker Anders Svensson scored a spectacular free kick to knock Argentina out of the World Cup and one of the best goals in this year's FA Cup in the 4-0 thrashing of Tottenham.
The first of the two, unrelated Svenssons, Anders joined Saints for £750,000 two years ago in Stuart Gray's brief reign and will probably partner Oakley in the FA Cup final.
He has the ability and the technique to dominate a game from his favoured position in the centre of midfield, but inconsistency and a lack of pace mean tougher tacklers are sometimes preferred.
Rory Delap (18) Born: July 6, 1976
Another who will probably miss out in Cardiff because of injury, £4 million signing Rory Delap is Saints' club record buy.
Versatile enough to have played both at right-back and centre-forward in his career, the Irish international suffered from playing in a variety of positions in his first season at St Mary's.
Selected in the centre of midfield this year, Delap's committed tackling and indefatigable approach made him a key member of the side until injuries struck.
Federico Arias (22) Born: April 24, 1979
Argentine winger who was signed in the January transfer window, Arias has yet to make his Saints debut.
But with two ineligible players and six who may be sidelined by injuries, he could be on the bench.
Arias, who is left-footed and can play on either flank, was known as 'The Torpedo' in South America because of his pace.
Fabrice Fernandes (29) Born: October 29, 1979
French winger who has settled at Southampton after brief spells at Fulham and Rangers, the left-footed Fernandes has been moved to the right wing this season by Strachan.
One of Saints' best players in the first half of the season, with his accurate crossing - using either foot - mesmerising skill and willingness to cut inside and shoot.
But Fernandes, the member of Saints' midfield who does least defending, has struggled to maintain that kind of form and was substituted after just half an hour in the 6-1 thrashing at Arsenal.
Chris Baird (32) Born: February 25, 1982
Northern Ireland Under 21 international right back who could become one of the least experienced players ever in the FA Cup final.
Baird made his Saints debut less than two months ago and his first start, in the centre of midfield, in the 1-0 win at Manchester City.
James Beattie (9) Born: February 27, 1978
England international striker who is Saints' Player of the Year after scoring 23 of their 43 Premiership goals.
The 25-year-old is a powerful target man with an aggressive style of play who cost just £800,000 from Blackburn in 1998.
Apart from his aerial strength, Beattie's goals have included penalties, free kicks, solo runs, long-range strikes and even a tap-in.
Kevin Davies (10) Born: March 26, 1977
Former Chesterfield striker who cost Blackburn £7.5 million five years ago but seems likely to leave Southampton on a free transfer when his contract expires this summer.
The burly Davies is actually a better dribbler than a header but, after three disappointing seasons, he was Saints' sixth-choice striker at one stage this season.
But the ability Davies, still only 26, has was evident in his two goals this season, both last-minute equalisers; a well-taken goal against Aston Villa and a vital strike against Millwall to keep Saints in the FA Cup.
Marian Pahars (17) Born: August 5, 1976
Another player likely to miss out with injury, Pahars finished as top scorer in two of his first three seasons at Southampton after an £800,000 move from Skonta Riga.
But 'the Latvian Michael Owen', who started the season as Beattie's regular partner, has only scored once in an injury-ravaged campaign.
Slight, quick and technically excellent, Pahars is perhaps the most gifted player at Southampton - as was recognised by then Coventry manager Gordon Strachan when he bid £6 million for the Latvian.
Jo Tessem (21) Born: February 28, 1972
Norwegian international who was a policeman before becoming a professional footballer and cost Saints £600,000.
Made his debut, to his bemusement, at right back and marked David Ginola out of the game, but prefers to play as an attacking midfielder, either on the right or in the centre.
However, Strachan has generally used Tessem as a striker where his opportunism, willing running and height have made him a regular substitute.
Brett Ormerod (36) Born: October 18, 1976
Former Blackburn trainee - alongside Beattie - who was released at Ewood Park and reached Saints via non-league Accrington Stanley and Blackpool.
Signed for £1.75 million by Strachan, Ormerod has impressed with his never-say-die attitude and Stakhanovite work ethic as he has taken advantage of the absences of Pahars and Agustin Delgado to become Beattie's regular partner.
A prolific scorer at lower levels, he has found goals harder to come by in the Premiership; his FA Cup semi-final strike against Watford was his first for five months and, though improving every year, he is certainly not a clinical finisher.
