Starting of as a Tottenham apprentice, he played for them alongside his brother Andy, also a former professional defender.
Polston spent virtually his entire career with Norwich City, signing for the Canaries for £250,000 in 1990 and making more than 200 league starts for the Carrow Road side.
He was a vital player within the Norwich side that finished third in the opening season of the Premier League in 1992/93, and was just as essential in the side that he captained at the club's first ever UEFA Cup match, scoring the second of three that night as they put one over Vitesse Arnhem.
After parting with Norwich in 1998 he travelled down the leagues to join Reading on a free. Polston debuted in a 2-1 win over Lincoln and scored at Madejski Stadium in a 1-1 draw with Oldham the following season.
He only managed 24 appearances, scoring one goal before injury struck. In 2001 he retired from the game upon failing to recover from a knee injury, instead taking up the profession of being a personal trainer.
