Manchester City Football Club, sometimes abbreviated to Man City, is a football club based in Manchester, England, that competes in the Premier League, the top flight of English football. The club has won five league titles, five FA Cups, five League Cups, five FA Community Shields, and one European Cup Winners' Cup. Founded in 1880, the club entered the Football League in 1899, and won their first major honour with the FA Cup in 1904. They had a period of success in the late 1960s, winning the League, FA Cup and League Cup under the management of Joe Mercer and Malcolm Allison. After losing the 1981 FA Cup Final, the club went through a period of decline, culminating in relegation to the third tier of English football. Having regained their Premier League status in the early 2000s, Manchester City was purchased in 2008 by Abu Dhabi United Group for £210 million, receiving considerable investment. The club subsequently won several trophies in the 2010s, and also became the only team to attain 100 points in a season. Manchester City's revenue was the fifth highest of a football club in the world in the 2017–18 season at €527.7 million.
