Passage: Woolwich Arsenal (nowadays simply Arsenal) were the first club in London to turn professional in 1891 and were one of the prime motivators behind an attempt to set up a Southern League to mirror the existing Northern and Midlands based Football League. However, this venture failed in the face of opposition from the London Football Association and Woolwich Arsenal instead joined the Football League as its only representative south of Birmingham in 1893. Additionally, an amateur league, the Southern Alliance was founded in 1892, with seven clubs from the region, but that folded after one incomplete season.
