In 1954 Blanchflower was bought by Tottenham Hotspur for a fee of £30,000, and during his ten years at White Hart Lane he made 337 League appearances, and 382 total appearances (scoring 21 goals). The highlight of his time at Spurs came with the 1960–61 season. With Blanchflower as captain Spurs won their first 11 games, a record for the top flight of English football and eventually won the league by 8 points. They then beat Leicester City in the final of the FA Cup to become the first team in the 20th century to win the League and Cup double, not achieved since Aston Villa in 1897.
