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 previous league title had been secured 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 with an 8-1 drubbing at the hands of Middlesbrough, a match that also marked the final appearance of manager Sven‑Goran Eriksson.

In the modern Premier League era, City had already suffered three relegations and, just a decade earlier, had briefly dropped into the third tier. The league’s major honours during the preceding sixteen seasons had been monopolised by Manchester United, Chelsea and Arsenal, leaving City far from the conversation.

Few observers could have imagined the dramatic reversal that would follow. Over the nine‑year window examined by the Premier League’s independent investigation, City amassed three league crowns, more than doubling their historic tally and establishing themselves as a new footballing powerhouse. However, the same investigation uncovered serious breaches of the competition’s financial regulations.

The report identified a series of "sham" commercial contracts and an artificial inflation of revenue amounting to roughly £830 million. Potential penalties range from hefty fines and transfer bans to outright expulsion from the league, with some voices even demanding that the club’s titles be stripped.

City have denied any wrongdoing and have signalled their intention to appeal. The scandal centres on what the commission calls a "disguised funding scheme". Under this arrangement, the Abu Dhabi United Group – the owners of Manchester City – paid extraordinarily large sponsorship fees that were recorded as commercial income.

This accounting trick allowed the club to fund an unprecedented spending spree on player acquisitions. From the summer of 2009 until the January 2018 transfer window, City shelled out about £1.2 billion on new players, according to Transfermarkt, outspending the next biggest spender, Chelsea, by nearly £300 million.

Their net outlay of £888.2 million dwarfed Manchester United’s £513.1 million, underscoring the scale of the investment. Year by year, the pattern is clear. In five of the nine seasons covered by the probe, City topped the league’s transfer‑spending chart, and they led the net‑spend rankings in six. The influx of world‑class talent began to bear fruit with the club’s first league triumph in 44 years during the 2011/12 season.

The two seasons preceding that historic win saw City spend £260.5 million on arrivals such as Carlos Tevez, Edin Džeko, Yaya Touré, David Silva, Mario Balotelli and James Milner – a core that laid the foundations for future success. Subsequent campaigns brought in further marquee names: Sergio Agüero, Samir Nasri, Fernandinho, Jesús Navas and Eliaquim Mangala arrived in the following four seasons, while the 2015/16 window added Kevin De Bruyne and Raheem Sterling to the roster. The most lavish spending year within the investigation period was 2017/18, when City invested £282.5 million in players including Aymeric Laporte, Benjamin Mendy, Kyle Walker, Bernardo Silva and goalkeeper Ederson.

That season culminated in a third Premier League title under the scrutinised era. During this time, the sponsorship fees paid by the Abu Dhabi United Group rose steadily for four consecutive seasons, reaching £134.7 million in 2017/18 compared with just £22.5 million in 2009/10.

The commission’s findings suggest 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 engineering enabled the club 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’s trophy cabinet filled with an FA Cup, three League Cups and a Community Shield, marking the most successful era in the club’s history. A graphical overview of City’s final‑league positions over the decades highlights the stark turning point during the investigated period, illustrating how the club vaulted from mid‑table obscurity to a dominant force in English football – a status it has largely maintained.

Since Sheikh Mansour’s arrival, City have finished outside the Premier League’s top three only once in the last sixteen seasons. Their eight league championships now place them second only to Manchester United in the Premier League era, overtaking both Chelsea and Arsenal. When pre‑Premier League titles are counted, City join the exclusive group of clubs – Manchester United, Liverpool and Arsenal – that have reached double‑digit league wins.

Nevertheless, the commission’s revelations cast a shadow over these achievements, suggesting that the transformation of Manchester City – and the broader reshaping of the football landscape – may have been underpinned by financial practices that breached the sport’s regulatory framework. The ongoing appeals process will determine whether the club’s honours stand or are altered, but the debate over fairness, transparency and the true cost of success continues to reverberate throughout the football world.
