During the 1932–33 English football season, Brentford competed in the Football League Third Division South. Brentford won the division championship and secured promotion to the second tier of English football for the first time in the club's history. Jack Holliday set a new club goalscoring record of 39 goals in a season, which as of 2023 has yet to be broken. It is statistically Brentford's second-best season, after 1929–30.
Brentford had a dream start to the Third Division South season, going undefeated and winning 12 of the opening 14 matches.[4] A new club record of 16 consecutive undefeated Football League matches was established, with the run stretching back to wins in the final two matches of the 1931–32 season.[5] The record stood until it was overtaken during 2013–14.[6] The Bees topped the table after the second match of the season.[4] After briefly dropping back to 2nd on goal difference, they quickly rose back to the summit and remained there until a 5–5 draw with Luton Town (which set a new club record for highest aggregate score in an away Football League match) on 1 February 1933 dropped the club back to 2nd.[4][7] Manager Curtis signed a new three-year contract in January 1933 and forward Jack Holliday was in prolific scoring form, hitting 26 goals in his first 20 appearances of the season, including four hat-tricks.[8] One of the hat-tricks comprised five goals in the draw with Luton Town,[8] which made Holliday the first player to score five goals for Brentford in a Football League match.[9]
Brentford went back to the top of the table after a 6–0 victory over Newport County on 4 February, the team's biggest victory of the season.[4] Aside from a minor blip in mid-March through to early-April, the Bees held onto top spot and clinched the Third Division South championship after a 2–1 victory over Brighton & Hove Albion on 26 April 1933,[4] with nearest rivals Exeter City five points behind with only two matches to play.[10] Brentford drew the remaining three matches of the season and were promoted to the Second Division for the first time in the club's history.[4][11]
Jack Holliday broke Billy Lane's three-year old club record for most goals in a season with four strikes in a 7–3 mauling of Cardiff City on 1 April and he finished the season with 39 goals in all competitions.[1][8] Despite his exploits, Holliday did not finish as the Third Division South's top scorer, due to Coventry City's Clarrie Bourton bettering Holliday's total of 38 by two goals.[12] A number of Football League club records were set during the season, including fewest away defeats (4), fewest defeats (6), most away goals scored (45) and most points (62 – two points for a win).[5] Brentford's average Football League home attendance of 13,300 was the highest in the Third Division South.[13] 1932–33 is statistically Brentford's second-best season, with the club having acquired 2.10 points per game under the current ruling of three points for a win.[6]
Brentford's reserve team finished as champions of the London Combination for the second successive season.[14] The team won all their home matches during the season, which formed a large chunk of the reserve team club record of 43 consecutive home victories, a run which ran from November 1931 to November 1933.[15]Ralph Allencaptained the team, scored a large chunk of the goals and the final match of the season versus Aldershot Reserves was played in front of a crowd of 9,000, a club record for a reserve team fixture.[15][16]
