I thought it was still a month or so away, we played Aston Villa in the 125 match in October I believe and that was supposed to be the closest home match to our anniversary.

The Day it all Began. This is accepted as the date of the formation of Tottenham Hotspur Football Club. It was formed when a group of schoolboys who played cricket for the Hotspur Cricket Club decided to form a football club for the winter months. It was known as Hotspur Football Club and as the first subscriptions were due on 5th September, 1882, this is taken as the date for the formation of the club. After two years due to confusion with another club, London Hotspur, the name Tottenham Hotspur was adopted. They played their first games on Tottenham Marshes and from such humble beginnings grew the world famous Spurs.
