Twelve men have played for Saints and their League Cup final rivals Manchester United since the Second World War - from Norman Kirkman to Morgan Schneiderlin.

Here, the Daily Echo looks back at the dozen who have represented both the Wembley finalists.

Norman Kirkman

The full back made unofficial appearances for Manchester United during the war, but never played a competitive game. Moved to Saints from Leicester in 1950, but made only 20 league appearances for the club. After spells managing Exeter City and Bradford Park Avenue he dropped out of football to become a baker. He later scouted for several clubs, including Saints.

Francis Burns

The left back made his United debut in 1967 and played in six European Cup ties in the club's run to the 1967/68 European Cup final, though he lost his place in the final to Shay Brennan. After 121 league appearances for United he joined Saints for £50,000 in 1972. He could not displace Joe Kirkup as first choice left back, though, and moved back to Lancashire to join Preston the following year after just 21 Saints games. At Deepdale he was reunited with former Old Trafford team-mate Bobby Charlton, who had just taken over as Preston boss. Indeed, Burns was his first signing.

Ron Davies

United boss Sir Matt Busby described the Welshman as 'the finest centre forward in Europe' after Davies had scored all Saints' goals in a 4-1 win at Old Trafford in August 1969.

Davies was a prolific scorer for Saints, with 85 goals in 119 First Division games in his first three seasons at The Dell.

His four-goal show at Old Trafford made up a third of his entire 1969/70 top flight tally, though.

He left Saints in March 1974 after netting 153 goals in 277 appearances.

In November 1974, he moved to Old Trafford, Tommy Docherty paying Pompey £43,000 for his services.

By this time, though, Davies' best days were long gone. He only made 10 appearances for United - eight in the Second Division and two in the FA Cup - and didn't score at all.

Jim McCalliog

A man for the big occasion, the midfielder scored for Sheffield Wednesday in the 1966 FA Cup final and for Wolves in the 1972 UEFA Cup final. However, he lost both finals - to Everton and Tottenham respectively.

McCalliog moved to Old Trafford in March 1974 for £70,000 from Wolves, but could not prevent the club being relegated to the second division (Saints went down the same season as well).

McCalliog started the 1974/75 season as a United regular but was sold in February 1975 to Saints for £40,000.

The player would go on to write his name into Saints folklore by providing the pass for Bobby Stokes to score the winner in the following year's FA Cup final against his former employers.

In the quarter final, he had struck the only goal at fourth tier Bradford City.

McCalliog played 72 games for Saints and scored eight goals before losing his place in January 1977 to new signing Alan Ball. He left at the end of the season to play in the North American Soccer League for Chicago Sting.

Ted MacDougall

A prolific scorer for AFC Bournemouth, MacDougall won a dream move to Old Trafford in September 1972 for a fee of almost £200,000.

He was to only play 18 times for United, though, with one of his four goals coming in a 2-1 win against Saints two months later.

Signing for Saints from Norwich for £50,000 in 1976, MacDougall was top scorer in his first season, 1976/77 - hitting 23 goals in 36 Second Division appearances.

Reunited up front with former Cherries strike partner Phil Boyer, MacDougall contributed 14 more goals as Saints win promotion to the top flight in 1977/78.

Despite five goals in the first 10 games of the 1978/79 First Division season, MacDougall told boss Lawrie McMenemy he no longer felt able to cut it at the highest level and was allowed to return to Cherries.

Danny Wallace

Handed his debut by Lawrie McMenemy as a 16-year-old at Old Trafford in November 1980, the winger moved there permanently for £1.3m almost nine years later.

His best days, without a doubt, were in Saints' colours.

He netted 64 goals in 253 appearances for the club , including 11 in the First Division when Saints finished runners-up to Liverpool in 1984.

While at United, he scored 11 goals in 71 appearances - helping the club win the 1990 FA Cup. He was a non playing sub when they won the European Cup Winners Cup 12 months later.

The emergence of first Lee Sharpe and then Ryan Giggs greatly reduced Wallace's chances, and he left to join Birmingham in October 1993 for £400,000.

Three years later he was diagnosed with multiple sclerosis and he was forced to retire from football.

In 2006, he completed the London Marathon in five-and-a-half days.

Joe Jordan

Signed by United for £350,000 in early 1978 from Leeds United, the Scottish international striker was to score 41 goals in 126 appearances for the club.

He left Old Trafford in the summer of 1981, AC Milan signing him for £325,000. Three years later, aged 32, he returned to England to sign for Saints for £150,000. There he was top scorer in his first season, 1984/85, with 12 league goals as Saints finished fifth. He moved onto Bristol City in 1987.

Mark Hughes

A legend at Old Trafford for his 120 goals in 354 appearances over two spells.

Anything but a legend at Saints, where he made 60 appearances after a £650,000 move from Chelsea in the summer of 1998 and only scored twice.

A far cry from his early days at United where he struck 24 league and cup goals in his second full season, 1984/85, before netting 17 in the league the following season.

That form won him a £2.5m move to Barcelona in the summer of 1986, but he returned to Old Trafford two years later for £1.5m.

He struck 21 times in all competitions in 1990/91, including two in the European Cup Winners Cup final win against Barcelona, and added 22 more in 1993/94 when United won the double for the first time.

He moved to Chelsea in 1995 and onto Saints three years later.

Andrei Kanchelskis

A flying winger at Old Trafford between 1991-1996 - where he scored 36 goals in 161 appearances - Kanchelski was given a one-year Saints contract by Gordon Strachan ahead of the 2002/03 season.

The Russian only appeared in one league game, against Everton as a sub, before leaving in the first ever January transfer window to join Saudi Arabians Al-Hilal on a free.

Danny Higginbotham

Only made seven first team appearances for United after coming through the ranks at Old Trafford, prior to moving to Derby. Signed for Saints in the January 2003 transfer window for £1.5m. Made 94 appearances for Saints before leaving to join Stoke in August 2006 for £225,000. Aged 34, and playing for non league Chester at the time, Higginbotham made his international debut in 2013 for Gibraltar.

Luke Shaw

The left back was only 17 when Nigel Adkins threw him in for his Premier League debut in November 2012.

But he never looked out of place and in March 2014, aged 18, made his senior England debut.

He went to that summer's World Cup and appeared in the draw with Costa Rica.

On his return to Saints, and after 60 league appearances for the club, he moved to Old Trafford for a whopping £27m.

That made him one of world football's most expensive teenagers.

In his two and a half seasons at United, Shaw has been restricted to just 28 league appearances.

He missed most of the 2015/16 season with a badly broken leg suffered in a Champions League fixture.

Still only 21, he has also struggled for regular football under Jose Mourinho.

Morgan Schneiderlin

Little did they know it at the time, but Saints had a bargain when they paid French club Strasborg £1.2m for an 18-year-old Schneiderlin in the summer of 2008.

He went on to become a key member of the club's rise from the depths of League 1 to the top seven of the Premier League, making 261 appearances in all competitions.

After three seasons as a Premier League regular with Saints, he moved to Manchester United for £25m in the summer of 2015.

Jose Mourinho's arrival last summer saw him fall out of first team favour, and last month he jumped at the chance to be reunited with his former Saints boss Ronald Koeman at Everton.

At £20m, he was the most expensive signing in the January transfer window.

 Alan McLoughlin was a trainee at Old Trafford who left without ever playing a first team game, McLoughlin became Saints' first £1m signing in December 1990 when he moved from Swindon. He only made 27 appearances, however, and within two years had moved to Pompey for £400,000.
