The following season, Stewart's success in the FA Cup continued as, having reached the quarter-finals in two of the previous three years, Cardiff reached their first final in 1925. However, they went on to lose 1–0 to Sheffield United. It would only take two years before the club returned to a final, this time in 1927. They faced Arsenal and the match was tied at 0–0 until Hughie Ferguson's shot was fumbled into the net by Dan Lewis in the 74th minute, giving Stewart the record of being the only manager ever to take the trophy out of England. They went on to complete a cup double by winning the Welsh Cup two weeks later against Rhyl and added the Charity Shield in October by defeating amateur side Corinthians.
