I'm glad we've gone on the attack. As a professional, I can assure people on this forum that breach of confidentiality in an investigation is an extremely serious matter undermining the integrity of any investigation where the breach has occurred. That is doubly the case where a) the breach is deliberate and b) the leak is to the press.
So much so, that City's lawyers must be all over this. UEFA's lawyers need to tell us a) who is leaking the material, b) what role they had on the investigation, c) why they are leaking the material, c) how they leaked the material d) what UEFA have done about the individual concerned and what steps they have taken to ensure the integrity of the investigation.
