A former player, who came to Tottenham in 1997 and reigned over a time of turmoil at the club.
Studying for a Geography degree at London University, John started at Millwall as a non-contract winger and was transferred to Reading in 1978, where he played for three seasons. At Elm Park, Alexander was a member of the Biscuitmen's squad that won promotion from the Fourth Division in 1979, but in 1981, he left to join Northampton Town.
After his playing days were over, John worked for the BBC in the finance team, where he learned how to deal with budgets and he went on to take up the post of assistant secretary at Watford. After seven years, he took the secretary's role when Eddie Plumley retired.
With Spurs looking for a replacement for club secretary Peter Barnes, Alexander came to White Hart Lane and has been in charge while chairmen and managers have come and gone.
