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 title had been won forty years earlier, and the team had just ended the 2007/08 campaign in ninth place, a full 32 points adrift of champions Manchester United.

That season concluded with an 8‑1 drubbing at the hands of Middlesbrough, a match that turned out to be the swansong for manager Sven‑Göran Eriksson. City’s recent past was far from glittering. In the Premier League era they had suffered three relegations and, only a decade before the takeover, had briefly slipped into the third tier of English football.

The league’s elite – United, Chelsea and Arsenal – had monopolised the last sixteen titles, leaving Manchester City out of the conversation entirely. Few observers could have imagined the radical transformation that would follow.

Over the nine‑year window examined by the Premier League’s independent investigation, City captured three league crowns, more than doubling their pre‑2008 tally and establishing themselves as a new powerhouse. Behind that meteoric rise, however, the commission uncovered serious breaches of the competition’s financial regulations.

Their report describes a series of “sham” commercial contracts and an artificial inflation of revenue by roughly £830 million. Potential penalties range from hefty fines and transfer bans to expulsion from the league, and some voices have even called for the club’s titles to be stripped.

Manchester City deny any wrongdoing and have said they will appeal. The scheme, labelled a “disguised funding scheme” by the investigators, involved the Abu Dhabi United Group – the owners of the club – paying massive sponsorship sums that were logged as commercial income.

This inflow of cash enabled City to embark on an unprecedented spending spree. According to Transfermarkt, between the summer of 2009 and the January 2018 transfer window the club shelled out about £1.2 billion on player acquisitions, almost £300 million more than the next biggest spender, Chelsea, which spent £931.7 million in the same period. City’s net spend of £888.2 million dwarfed that of Manchester United, the next‑highest net spender, whose figure stood at £513.1 million.

Year after year the scale of the outlay was evident. In five of the nine seasons covered by the probe, City topped the league in total transfer spend, and they led the chart for net spend in six seasons.

The roster of signings reads like a who’s‑who of modern football talent, many of whom were instrumental in the club’s subsequent triumphs. The first major trophy after the takeover arrived in 2011/12, ending a 44‑year wait for a league crown. In the two seasons leading up to that historic win, City spent £260.5 million on arrivals that included Carlos Tevez, Edin Džeko, Yaya Toure, David Silva, Mario Balotelli and James Milner – a group that laid the foundations for a genuine title challenge. The following four campaigns saw further marquee signings such as Sergio Aguero, Samir Nasri, Fernandinho, Jesús Navas and Eliaquim Mangala.

Spending accelerated again in 2015/16 with the arrivals of Kevin De Bruyne and Raheem Sterling, players who would become central to the club’s style of play. The peak of the investigation’s timeframe was the 2017/18 season, when City secured their third league title of the period after investing £282.5 million in new talent, including Aymeric Laporte, Benjamin Mendy, Kyle Walker, Bernardo Silva and goalkeeper Ederson. During that season the sponsorship payments from the Abu Dhabi United Group rose for the fourth consecutive year, reaching £134.7 million – a stark increase from the modest £22.5 million recorded in 2009/10.

The commission calculated that the £830 million falsely recorded as commercial revenue between 2009/10 and 2017/18 represents roughly 70 percent of City’s total £1.2 billion transfer expenditure. This inflated income allowed the club not only to buy top‑class players but also to attract three elite managers – Roberto Mancini, Manuel Pellegrini and Pep Guardiola – each of whom benefitted from the deep pockets at their disposal. Beyond the league titles, City added an FA Cup, three League Cups and a Community Shield to their trophy cabinet during this era, making it the most successful period in the club’s history.

A visual representation of the club’s league finishes over time highlights the dramatic shift, with City emerging as a dominant force in English football – a status they have largely maintained since. When Sheikh Mansour arrived, City were a mid‑table side.

In the sixteen seasons that have followed, they have finished outside the top three only once. They are now eight‑time league champions, trailing only Manchester United in Premier League titles and having overtaken both Chelsea and Arsenal in the overall count. When pre‑Premier League triumphs are considered, City join the exclusive group of clubs – alongside United, Liverpool and Arsenal – that have reached double‑digit league titles. Nevertheless, the commission’s findings cast a stark light on the club’s achievements and on the broader transformation of the football landscape.

The alleged financial manipulation raises questions about competitive fairness and the integrity of the sport, prompting ongoing legal battles and intense public debate about the future of Manchester City’s legacy.
