When Sheikh Mansour took control of Manchester City in September 2008, the club was still a modest side with only two top‑flight championships in its 114‑year history. The most recent league triumph had arrived forty years earlier, and the team had just concluded the 2007/08 campaign in ninth place, a full 32 points adrift of champions Manchester United. That season ended in a humiliating 8-1 defeat to Middlesbrough, marking the final match for manager Sven‑Goran Eriksson.

In the years preceding the takeover, City had endured three Premier League relegations and, only a decade before, had slipped as low as the third tier of English football. The league’s elite titles had been monopolised by Manchester United, Chelsea and Arsenal, leaving City far from the conversation about title contenders. No one could have foreseen the dramatic turnaround that would follow. Over the nine‑year span examined by the Premier League’s independent investigation, City secured three Premier League crowns, more than doubling their historic tally and establishing themselves as a new powerhouse.

However, the same investigation uncovered serious breaches of financial regulations, describing a "sham" sponsorship arrangement that artificially inflated the club’s commercial revenue by roughly £830 million. Potential penalties range from hefty fines and transfer bans to possible expulsion from the league, with some voices even demanding that the club’s honours be stripped.

City have denied any wrongdoing and have signalled their intention to appeal. The report labels the scheme a "disguised funding" operation. In essence, the Abu Dhabi United Group – the owners of the club – paid enormous sums to entities that were presented as commercial partners, allowing the money to be logged as sponsorship income. This inflow of cash paved the way for an unprecedented spending spree on player acquisitions.

Between the summer of 2009 and the January 2018 transfer window, Transfermarkt records show City splashed about £1.2 billion on transfers, outspending the next‑biggest spender, Chelsea, by nearly £300 million. Their net outlay of £888.2 million dwarfed United’s £513.1 million, highlighting the scale of the financial firepower at City’s disposal.

Year after year, the club topped the Premier League charts for total transfer spend in five of the nine seasons under review and led the league for net spend in six. The influx of world‑class talent was relentless.

The first major wave, arriving before the historic 2011/12 title, included names such as Carlos Tevez, Edin Džeko, Yaya Toure, David Silva, Mario Balotelli and James Milner. These signings laid the groundwork for a squad capable of challenging for silverware. Subsequent windows saw the arrival of Sergio Aguero, Samir Nasri, Fernandinho, Jesús Navas and Eliaquim Mangala, while the 2015/16 season brought in Kevin De Bruyne and Raheem Sterling – players who would become central to City’s style of play.

The most lavish season covered by the investigation was 2017/18. That year City spent £282.5 million on players such as Aymeric Laporte, Benjamin Mendy, Kyle Walker, Bernardo Silva and goalkeeper Ederson, culminating in a third Premier League title within the period under scrutiny.

Throughout this era, the sponsorship fees paid by the Abu Dhabi United Group rose steadily, reaching £134.7 million in 2017/18 after starting at just £22.5 million in 2009/10. The commission’s findings estimate that the £830 million falsely recorded as commercial revenue between 2009/10 and 2017/18 represents roughly 70 percent of City’s total transfer expenditure. This financial muscle also allowed City to attract three elite managers – Roberto Mancini, Manuel Pellegrini and Pep Guardiola – each of whom benefited from the club’s deep pockets to assemble squads that could compete at the highest level. Under their stewardship, City added an FA Cup, three League Cups and a Community Shield to their trophy cabinet, marking the most successful period in the club’s history.

A visual representation of City’s league positions over time underscores the seismic shift that occurred during these years, illustrating the club’s rise from mid‑table obscurity to a dominant force in English football – a status they have largely maintained since. Since Sheikh Mansour’s takeover, City have finished outside the top three only once in sixteen seasons, a stark contrast to their pre‑2008 record. Today, with eight league titles, City sit second only to Manchester United in Premier League triumphs, having overtaken both Chelsea and Arsenal. When historic pre‑Premier League titles are counted, they join an exclusive group of four clubs – Manchester United, Liverpool, Arsenal and themselves – that have reached double‑digit league championships.

Nevertheless, the commission’s revelations cast a long shadow over these achievements. By exposing a period in which financial manipulation helped reshape the competitive balance of English football, the report forces a re‑examination of City’s legacy and raises fundamental questions about the fairness of a system where vast private wealth can be funneled into a club under the guise of commercial sponsorship.

The ongoing appeals and potential sanctions will determine whether the club’s recent history will stand as a testament to strategic investment and footballing excellence, or be rewritten as a cautionary tale of rule‑breaking that altered the sport’s landscape.
