Greater success for Manchester City in the FA Cup would follow in subsequent seasons. Brook played in consecutive FA Cup finals in the mid-1930s, collecting a winners medal on the second occasion. In the 1933 FA Cup Final he was part of the Manchester City team that was defeated three goals to nil by Everton, who were captained by his England teammate Dixie Dean. The Everton team also included former City player Tommy Johnson. Brook was in fine form in that year's competition, scoring twice in a 2–0 victory against Walsall in the fourth round and a hat-trick against Bolton Wanderers in a 4–2 victory in the fifth round. Brook also set up Tilson, to score City's fourth goal in the game against Bolton. Following the game against Bolton, Brook was described as 'one of the most dangerous wingers in the country'. In the semi-final against Derby County he set up two goals in a 3–2 victory. For the first goal, he 'beat international full-back Cooper and centred for right winger Toseland to score from close range'. He then 'lobbed beautifully for Tilson to run between two defenders and head the second Brook was the first player to wear the number 12 shirt in an FA Cup final as Everton wore 1–11 and City wore 12–22. One journalist contended that 'if Manchester City had had five Eric Brooks in the forward line there might have hem very different story to tell the in the final'. Brook's performances in 1933 led to him being described as 'probably the strongest outside left in contemporary play, for he is as hard as nails'. Brook contended that to succeed at outside left, a player should use 'plenty of tricks' and be 'cunning, deceptive, speedy and accurate'. In the 1934 FA Cup Final Brook set up the winning goal, which was scored by his friend Fred Tilson, to earn City a 2–1 victory over Portsmouth. Brook had scored a 'wonder goal' in front of a record crowd of 84,569 against Stoke City in the sixth round of that year's competition. According to Gary James, 'many fans from the 1930s claimed it was the greatest City goal ever scored at Maine Road'. Brook had made 'a speculative lob' from the wing, which seemed to change direction in mid-flight, which curled past Stoke goalkeeper Roy John. Some claimed that Brook's lob was a cross, but those who knew Brook said it was the type of unconventional thing he would try.
