manager Harry Curtis made minor additions to his squad in the 1934 off-season, his only significant purchases being left backGeorge Poyser from Port Vale for a club record £1,150 fee and goalkeeperJames Mathieson from Middlesbrough. After two years on the fringes, young right halfDuncan McKenzie would break into the first team squad during the season and George Robson would return in attack, having been frozen out during the previous season. Once the season got underway, despite 1933–34's leading scorers Jack Holliday and Idris Hopkins finding the net, it was Ernest Muttitt who inspired the Bees to start the season with a seven-match unbeaten run – a run which took the club to the top of the table, with Muttitt scoring seven goals in a five-match spell. Aside from two separate spells of three defeats in five matches in September–October 1934 and December–February 1935, Brentford went on two long unbeaten runs during the season and after a 1–0 win over Notts County on 2 March returned the Bees to the top, the team would not be toppled and won the title with two matches to spare after a 3–3 draw with Barnsley on 27 April. A loss and a win in the final two matches saw Brentford confirmed as champions, five points above nearest challengers Bolton Wanderers and West Ham United. The promotion meant that Brentford would play in the First Division for the first time in the club's history and the championship shield was held aloft by captainHerbert Watson after the final match of the season at Griffin Park. A number of Football League club records were set or equalled during the season, including least home defeats, consecutive home matches undefeated and Billy Scott became the second Brentford player since the club joined the Football League to score five goals in a match, having netted five times in an 8–1 thrashing of Barnsley on 15 December 1934. He scored a further hat-trick in the return match with Barnsley on 27 April 1935. With his hat-trick versus Port Vale on 20 April 1935, Jack Holliday set a club record of 9 hat-tricks. The club record for highest winning margin in a Football League match was broken twice during the season, first in the 8–1 victory over Barnsley in December 1934 and then in the 8–0 hammering of Port Vale in April 1935. The eight-goal winning margin would stand as the club record until October 1963. A unique double was achieved during the 1934–35 season with Brentford's first-ever victory in the London Challenge Cup. Millwall were beaten 2–1 after extra time in the final at Craven Cottage.
