He spent the summer of 1993 playing in Norway with Lyn Oslo before playing out his career at Bournemouth, retiring from professional football in 1995.

Document 3: Carl Hoddle: The younger brother of England international Glenn Hoddle, Carl began his career with Tottenham Hotspur in 1984. After two years he moved to Barnet, where he stayed until 1988 before moving to Bishop's Stortford in a swap deal for former Barnet player Ian Fergusson. After one season he was signed by Leyton Orient, where he played 29 times, before returning to Barnet in 1991, ending his senior career in 1995 after 100 appearances. He also had a spell with Conference National side Woking. One notable game he played for the Bees was in the FA Cup against Chelsea in 1994, who were at the time managed by his older brother. He later worked in the used car trade and as a pub landlord before joining his older brother as a coach and scout at Wolverhampton Wanderers between 2004 and 2006. He died on 2 March 2008 after he was found collapsed in his home from what was initially suspected to be a heart attack but later confirmed as a brain aneurysm.
Document 4: Tottenham Hotspur F.C.: Spurs were one of the five clubs that pushed for the founding of the Premier League, created with the approval of The Football Association, replacing the Football League First Division as the highest division of English football. Despite a succession of managers and players such as Teddy Sheringham, Jürgen Klinsmann and David Ginola, for a long period in the Premier League until the late 2000s, Spurs finished mid-table most seasons with few trophies won. They won the League Cup in 1999 under George Graham, and again in 2008 under Juande Ramos. Performance improved under Harry Redknapp with players such as Gareth Bale and Luka Modrić, and the club finished in the top five in the early 2010s.
Document 5: FA Cup: Since the creation of the Football League in 1888, the final has never been contested by two teams from outside the top division, and there have only been eight winners who were not in the top flight: Notts County (1894); Tottenham Hotspur (1901); Wolverhampton Wanderers (1908); Barnsley (1912); West Bromwich Albion (1931); Sunderland (1973), Southampton (1976) and West Ham United (1980). With the exception of Tottenham, these clubs were all playing in the second tier (the old Second Division) -- Tottenham were playing in the Southern League and were only elected to the Football League in 1908, meaning they are the only non-League winners of the FA Cup since the League's creation. Other than Tottenham's victory, only 24 finalists have come from outside English football's top tier, with a record of 7 wins and 17 runners - up: and none at all from the third tier or lower, Southampton (1902, then in the Southern League) being the last finalist from outside the top two tiers.
Document 6: George Piper (footballer): A half-back, Piper began his career with Northfleet, a club which at the time acted as a nursery club for Tottenham Hotspur. He signed for Tottenham as a professional in January 1940, but with competitive football suspended due to the Second World War, he was restricted to playing in unofficial wartime competitions. Before The Football League resumed, he was released by Spurs and joined Gillingham of the Southern League. For the next four seasons he played regularly as Gillingham dominated the competition, making 116 Southern League appearances in all. In 1950, however, Gillingham were elected back into The Football League and signed Harry Ayres from Fulham to play in the half-back position. After making only four appearances during the 1950–51 season, Piper left to join Dartford.
Document 7: List of football clubs in England by competitive honours won: England's first football competition, the FA Cup, began in the 1871 -- 72 season, making it the oldest football competition in the world. Arsenal hold the record number of wins, with 13. League football began in the next decade with the founding of The Football League in 1888 -- 89. The name First Division was adopted in 1892, when The Football League gained a second division. The First Division remained the highest division of the English football league system until 1992, when the Premier League was founded. Manchester United have won the most top division titles, with 20. The English equivalent of the super cup began in 1898 with the inauguration of the Sheriff of London Charity Shield, pitting the best professional and amateur sides of the year against each other.

The Football League created its own knockout competition in 1960, the League Cup. The Anglo - Italian League Cup was created in 1969 to match English cup winners against the winners of the Coppa Italia, and was permanently disbanded in 1976. In 1985, the Full Members Cup and Football League Super Cup were created as substitutes for UEFA competitions after UEFA responded to the Heysel Stadium disaster by banning English clubs. They finished in 1986 and 1992 respectively. The Football League Centenary Trophy marked The Football League's 100th birthday, in the 1988 -- 89 season.
