After the First World War put a halt to football activity in the town, the game returned in 1919 when Worksop Town and Manton Athletic merged to become Worksop and Manton Athletic, although the Worksop Town name remained in popular usage. The club joined the Midland League and in 1921 won the competition for the first time. The 1920s provided the club with their best spell in the FA Cup, reaching the 1st Round in four out of six seasons from 1921. In 1923 they drew Tottenham Hotspur at White Hart Lane – the Tigers pulled off a shock by holding Spurs to goal-less draw. The Worksop board decided against hosting the replay at Central Avenue, and they were beaten 0–9 in the replay two days after the original tie, again at White Hart Lane. In 1926 they reached the 2nd Round for the first time after beating Coventry City at Central Avenue in the 1st Round – eventually losing by the odd goal in three to Chesterfield in the next round.
