The 1921–22 season was the 21st season of competitive football played by Cardiff City F.C. and the team's first in the First Division of The Football League. Cardiff had won promotion the previous season by finishing as runners-up in the Second Division, becoming the first Welsh team to reach the top tier of English football. Cardiff had a difficult start to the season, losing the first six matches of the campaign. They eventually saw results improve and finished in fourth place. The club entered the FA Cup in the first round and progressed to the fourth, before being defeated by Tottenham Hotspur after a replay. Cardiff went on to win the Welsh Cup for the third time in the club's history after defeating Ton Pentre 2–0 in the final, having scored seventeen goals and conceded only one during their cup run. During the season, 31 players made at least one appearance for the club. Billy Grimshaw played in more games than any other player, featuring in 47 matches in all competitions. Len Davies finished the season as the side's highest goalscorer with 30 in all competitions, a new club record. His tally of seventeen in the First Division was three short of Jimmy Gill's total, but his fourteen in cup matches, including eight in four appearances in the Welsh Cup, saw him outscore his teammate. The highest attendance recorded at Ninian Park was 51,000 for the FA Cup fourth-round tie against Tottenham. The league fixture against Tottenham recorded an attendance of 50,000 although an extra 6,000–10,000 were estimated to have broken into the ground after turnstiles were closed. The average league attendance during the season was 27,500. (en)
