If that is true then "they" I presume by this you mean UEFA, must be about to investigate the illegally obtained documents then?
Im sure City's legal department are waiting to be notified of such an investigation and the presentation of any forthcoming damning evidence in order to ask any legal body, committee, bench, panel or other investigative representative to have it immediately made inadmissible on the grounds of being illegally obtained.
Personally I think this is made up bollocks, more statements of fact with no factual basis whatsoever. The press are good at it.
