Manchester City Football Club, founded in 1880 as St. Mark's (West Gorton) before becoming Manchester City in 1894, is a prominent English professional club competing in the Premier League from their home at the City of Manchester Stadium. After winning their first major honour, the FA Cup, in 1904, the club enjoyed a successful period in the late 1960s and early 1970s under Joe Mercer and Malcolm Allison, securing multiple domestic and European trophies before experiencing a decline, including relegation in 1998.

A pivotal moment arrived in August 2008 with the takeover by Sheikh Mansour's Abu Dhabi United Group, ushering in a new era of significant financial investment and ambition. This transformation led to numerous Premier League titles—including four consecutive from 2020–21—and under manager Pep Guardiola, they achieved a historic domestic treble in 2018–19 and won their first UEFA Champions League in 2023, completing a continental treble. Consequently, Manchester City is now recognized as one of the world's most successful and financially powerful clubs, topping the Deloitte Football Money League in 2021–22 with the highest revenue globally.
