Question: How many total London clubs have played in the UEFA Champions League? Passage:Football is now the most popular spectator sport in London, and the city has several of England's leading clubs. Most London clubs are named after the district in which they play (or used to play). Historically the London clubs have not accumulated as many trophies as those from the north-west of England, such as Liverpool and Manchester United, but at present Arsenal (founded at Woolwich Arsenal but playing in Holloway), and Chelsea (who actually play in Fulham) are regarded as two of the Premier League's "big four" alongside Manchester United and Liverpool. In 200304 they became the first pair of London clubs to finish first and second in the top flight, with Arsenal winning. In 200405 they did so again, this time with Chelsea winning. In 200910, three of the top four places were occupied by London sidesChelsea (champions), Arsenal (3rd) and Tottenham Hotspur (4th). This meant that the 201011 season would see three London clubs in the UEFA Champions League for the first time ever.
