Input: Article: Arsenal appointed Herbert Chapman as manager in 1925. Having already won the league twice with Huddersfield Town in 1923–24 and 1924–25 (see Seasons in English football), Chapman brought Arsenal their first period of major success. His revolutionary tactics and training, along with the signings of star players such as Alex James and Cliff Bastin, laid the foundations of the club's domination of English football in the 1930s. Under his guidance Arsenal won their first major trophies – victory in the 1930 FA Cup Final preceded two League Championships, in 1930–31 and 1932–33. In addition, Chapman was behind the 1932 renaming of the local London Underground station from "Gillespie Road" to "Arsenal", making it the only Tube station to be named specifically after a football club.

Now answer this question: What football club manager got an underground station renamed for Arsenal?

Output:
Chapman
