If England is the only team in a region or city, or the team representing the whole region, it likes to be called United, which means unity. Manchester United is Manchester United, West Ham United is West Ham United, Sheffield United, Newcastle United and so on. Manchester city is Manchester city, which means city team, which is intended to be different from Manchester United. As for Queen's Park, it is also a place name, and the team name of Ranger Ranger has been updated. Because there are too many teams in London, all representing their respective districts.
Generally, a city has only one team at the beginning, so it is named after the city. Then there was another team, so we had to choose another name. In fact, the same is true in La Liga. For example, Real Madrid and Atletico Madrid, and a Getafe. Such as Barcelona and Spain.
Compared with Bundesliga and Ligue 1, it is relatively neat. Basically, a city has only one team. There is almost no derby in the same city. It is also related to the development of football industry.
