City have responded
Manchester City welcomes the opening of a formal UEFA investigation as an opportunity to bring to an end the speculation resulting from the illegal hacking and out of context publication of City emails.
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.
This looks like a few words have been exchanged and UEFA have said, "Look we have to be seen to at least investigate it, but nothing will happen."
