The most severe punishment has been announced for Man City for breaking financial fair play rules

Manchester City have submitted legal challenges against the Premier League charging them with 115 counts of alleged breaches of financial fair play rules between 2009 and 2018.
City was accused by the Premier League of withholding accurate financial data for those nine seasons. Other accusations focused on the nature of Roberto Mancini’s compensation, breaking UEFA rules, and refusing to help with the probe.
UEFA penalized City £49 million in 2014 for alleged Financial Fair Play violations. Then, in 2020, they were given a two-year suspension from participating in European events; however, this punishment was subsequently overturned after an appeal to the Court of Arbitration for Sport.
Additionally, German newspaper Der Spiegel has been publishing bombshell articles since 2018 about the City’s finances. The club, though, has consistently denied financial impropriety.
Now, the day after reaching the Champions League final for the second time following an emphatic 4-0 win over Real Madrid, it has been reported that City are officially disputing the ‘legality’ of the investigation and the involvement of a particular individual.
The Times writes that City have raised a challenge with regard to recent Premier League changes, arguing that those regulations should not apply to investigations of activity prior to that. They have also taken issue with Murray Rosen KC, who is head of the Premier League’s independent judicial panel and therefore appoints the chair of the disciplinary commission, potentially even appointing himself. City’s issue is that Rosen’s website says he is an Arsenal member.
