Career
He was a defender who began his career with Tottenham before playing for Norwich City and Reading. In March 1990, they became the first brothers to play together in the Spurs first team since 1912, although neither was a regular player and Andy played just once for Spurs. John left Spurs in 1990, after making 28 appearances for the club, when Norwich manager Dave Stringer paid £300,000 for him.
Following his release from Norwich in 1998, Polston joined Reading.
Polston retired from football in April 2001 after failing to recover from a knee injury. John is now a personal trainer.
