Bayern Munich have issued a warning to Manchester City over Financial Fair Play rules.
A senior Bayern executive insisted they have “no agenda” against City – managed by their old boss Pep Guardiola – but want UEFA to get tougher on clubs they suspect are not complying.
City successfully overturned a two-year ban from European competitions which UEFA had fought hard to enforce, arguing they were guilty of “serious breaches” of Financial Fair Play.
The Court of Arbitration for Sport cancelled the punishment last month due to a lack of evidence, though it accepted that City did not cooperate properly with UEFA’s investigation.
But the court ruling has not kept rival clubs and officials from criticising City’s financial approach, which they believe makes it harder to create a level playing field between teams.
Oliver Kahn, the former Bayern goalkeeper who joined the board in January and will take over as its chief executive next year, said football needs to take the regulations “more seriously”.
Kahn said: “I don’t know the situation exactly now in Man City or PSG or other clubs but I think we should take this FFP in the future more seriously.
“We need a clear structure and serious FFP so that we get more balanced competition.
He added: “If in the future you only have the same clubs winning the Champions League or winning, for example, the Bundesliga or Premier League or other leagues, I think it’s getting a little bit boring.
“So, I think we should do everything to get really strong FFP.”
La Liga president Javier Tebas also vented his anger at the outcome and questioned the role of the Court of Arbitration for Sport in making such significant calls.
Tebas told reporters: “We have to reassess whether the CAS is the appropriate body to which to appeal institutional decisions in football.
“Switzerland is a country with a great history of arbitration, the CAS is not up to standard.”
