Manchester City could be banned from the Champions League, perhaps as early as next season, as Uefa looks set to take strong action should the club be found guilty of an alleged £60million payments deception revealed during the Football Leaks scandal. Both Uefa and the Premier League are investigating after emails leaked by German publication Der Spiegel appeared to show £59.5million, reported as coming from sponsors Etihad airline was actually from Abu Dhabi United Group which owns Manchester City. Various English newspapers, including The Telegraph and the Daily Mail published articles talking about the possibility Manchester City could be excluded from the Champions League for financial doping. This comes in the wake of comments by Yves Leterme, chairman and chief investigator of UEFA’s Club Financial Control Body who stated to a Belgian media outlet that the English club could receive the “heaviest punishment” where revelations, previously published by Der Spiegel, prove to be true. Speaking to Belgian outlet Sport and Strategy, Leterme said: “If it is true what has been written, there might be a serious problem. This can lead to the heaviest punishment: exclusion from the Uefa competitions. “If the information is correct, this possibly goes against truthful reporting. The financial fair play rules are based on a system of declaration, three months after the clubs have closed their accounts, they have to deposit their figures. "Then we do random checks on the truthfulness of those figures. The accounts are examined and approved internally and externally." In effect, according to the claims, Manchester City owners were funding the sponsorship deals, something which is not allowed under Financial Fair Play rules. City have been sanctioned over financial fair play before, fined £49million in 2014 as well as having their Champions League squad capped.
