Manchester City face an uncertain immediate future in European competition after UEFA announced a two-season ban for the Premier League club on Friday.
European football's chief governing body, who also administered a €30million fine, ruled City were guilty of "serious breaches" of its Financial Fair Play (FFP) regulations.
It marked the end of a lengthy probe into City's financial affairs, which was launched following a series of allegations made by German publication Der Spiegel in November 2018.
City denied any wrongdoing throughout the process and immediately announced their intention to appeal against the decision.
Below we take a look back at how this point was reached.
November 2018: Football Leaks allegations emerge
It has been 15 months since Der Spiegel published a host of articles claiming the defending Premier League champions flagrantly flouted UEFA's FFP laws. The German publication purportedly gained the information from whistleblowers Football Leaks and claimed Sheikh Mansour's City regime topped up multi-million-pound sponsorship deals with Abu Dhabi companies, using their owner's fortune, to meet the financial rules. It was also claimed City were cut a favourable deal by UEFA for overspending in 2014. City said in response: "The attempt to damage the club's reputation is organised and clear".
November 2018: UEFA warns City FFP investigation could reopen
UEFA said it would consider reopening a 2014 probe, which saw City fined and have restrictions on the size of Champions League squad imposed, if "new information comes to light". Early in December, UEFA president Aleksander Ceferin said: "We are assessing the situation. We have an independent body working on it. Very soon you will have an answer on what will happen in this concrete case."
March 2019: UEFA launches formal investigation
It was almost a year ago UEFA formally started an investigation into Der Spiegel's allegations, with Club Financial Control Board chairman and former Belgium prime minister Yves Leterme warning the "heaviest punishment" City face is "expulsion from UEFA competitions". City said: "The accusation of financial irregularities are entirely false. The club's published accounts are full and complete and a matter of legal and regulatory record".
May 2019: City respond to ban reports
After reports emerged in the New York Times that City were facing the prospect of a one-year UEFA ban, the club released a statement registering concern that their "good faith" in UEFA's investigation into their financial affairs could be "misplaced".
May 2019: "Hostile process" slammed by City
Leterme had earlier in the year told Belgian magazine Sport and Strategy that City should face a ban from UEFA competition if the allegations were proven. A strongly worded club statement slammed the CFCB investigation as a "hostile process" after the probe was referred to the body's adjudicatory chamber for a final decision after the completion of Leterme's inquiry. The club said they were "disappointed but regrettably not surprised" by the decision.
November 2019: Reports say City set to avoid ban
Towards the back end of last year, it was reported UEFA were struggling to enforce its FFP regulations and City could avoid a ban and escape only with a fine.
November 2019: CAS deems City appeal 'inadmissible'
In June last year, City appealed against UEFA's investigation into alleged breaches of FFP to the Court of Arbitration for Sport (CAS). However, five months later CAS ruled City's appeal as "inadmissible" because UEFA had not reached a final decision on the case.
February 2020: UEFA announces ban
After a lengthy process, UEFA announced City have been hit with a two-year ban from European competition and a hefty €30million fine. The Adjudicatory Chamber of the CFCB found City guilty of "overstating its sponsorship revenue in its accounts and in the break-even information submitted to UEFA between 2012 and 2016". City again questioned the process of the investigation and announced their intention to launch an appeal with CAS "at the earliest opportunity".
