Four goals by Johnson helped Sheffield United defeat amateur side Corinthian F.C. 5–0 in the first round of the cup in front of a home crowd of 38,167. This set up a second round tie against local rivals The Wednesday who took a two goal lead in the opening ten minutes. Goals from Sampy and Green drew United level before half-time and another goal by Sampy early in second half gave United a 3–2 win.
United were given another home tie in the third round where a single goal by Tunstall was enough to give them a win over Everton in what was, at the time, a record attendance at Bramall Lane of 51,745. This figure was surpassed in the fourth round as 57,197 watched goals by Tunstall and Johnson give United a 2–0 home win against West Bromwich Albion.
For United’s next match they travelled to Stamford Bridge to face Second Division side Southampton. It was United’s seventh appearance in the semi-final of the competition (and 100th cup tie overall). An own goal late in the first half gave United the lead. After the break Southampton had a chance to draw level but their penalty was saved by Sutcliffe. This was soon followed by a goal from Tunstall securing a 2–0 win and a place in the final.

Cardiff faced Darlington in the first round of the cup. After two goalless draws the tie was decided with a third match at the neutral venue of Liverpool. Cardiff knocked out the Third Division North side with second half goals from Len Davies and Willie Davies to give a 2–0 win and set up a home tie against Fulham. Cardiff’s second round match was played in a heavy downpour that caused play to be temporarily suspended. A Len Davies goal late in the first half was enough to give Cardiff a 1–0 win.
Cardiff travelled to Meadow Lane for their third round tie against Notts County which they won 2–0 thanks to goals from Nicholson and Gill. Cardiff hosted Leicester City in the fourth round where after a goalless first half Beadles gave Cardiff the lead, only for Duncan to level the score. In the final minute Willie Davies scored directly from a corner to send Cardiff through with a 2–1 win.
The semi-final saw Cardiff return to Meadow Lane as a neutral venue for their match with Blackburn Rovers. Early goals from Nicholson, Gill and Willie Davies gave Cardiff a 3–0 lead at half-time. McKay replied for Blackburn with a headed goal after the break but the game finished 3–1 to Cardiff.
