The 1970–71 season was Cardiff City F.C.'s 44th season in the Football League. They competed in the 22-team Division Two, then the second tier of English football, finishing third.[1]
The club's season was disrupted by the sale of John Toshack to Liverpool in November,[2] breaking up the Toshack-Brian Clark strike partnership which had scored countless goals for the club in recent years. Despite this the team reached the quarter-finals of the European Cup Winners Cup before losing 2–1 on aggregate to Spanish side Real Madrid, after winning the first leg 1–0 at their home ground Ninian Park, a result that has since gone on to become one of the most famous moments in the club's history.[3]
