In Manchester City's first extended response to their European ban, chief executive Ferran Soriano insists the allegations are "false".
The club have been hit with a two-year suspension from European competition by UEFA after being found guilty of Financial Fair Play rule breaches - a ruling the club intend to appeal at the Court of Arbitration for Sport.
And Soriano was firm in City's stance, saying they will do everything they can to prove that the allegations are false.
"Well the most important thing I have to say today is that the allegations are not true. They are simply not true.
"The fans can be sure of two things. The first one is that the allegations are false. And the second is that we will do everything that can be done to prove so.
"We know the fans are supporting us. We can feel it. MCFC fans have gone through challenges over the decades. This is just another challenge. We will stick together, we will go through it and we will not let the fans down.
"The owner has not put money in this club that has not been properly declared. We are a sustainable football club, we are profitable, we don't have debt, our accounts have been scrutinised many times, by auditors, by regulators, by investors and this is perfectly clear.
"We are looking for an early resolution obviously through a thorough process and a fair process so my best hope is that this will be finished before the beginning of the summer and until then for us, it is business as usual."
Pep Guardiola has told Manchester City players he is committed to the club, saying: "Even if they put us in League Two, I will still be here."
Soriano insists both the manager and players are fully focused on the football side of the club, and remain calm.
"Obviously, [Pep] has been kept informed about this process but this is not something for him to respond to. He is focused on the football, he is focusing on the game, the game at hand, the game today, tomorrow and the next weeks.
"As well as the players. They are calm, they are focused and this matter is more a business matter, a legal matter than a football matter."
