Initially, football in London was dominated by amateur teams, drawing their membership from former public schoolboys but gradually working-class sides came to the forefront. Royal Arsenal was London's first professional team, becoming so in 1891,[10] a move which saw them boycotted by the amateur London Football Association. Other London clubs soon followed Arsenal's footsteps in turning professional, including Millwall (1893), Tottenham Hotspur (1895), Fulham (1898) and West Ham (1898).
