So he's provided German and French authorities these files but also says:
"'We haven't released the information yet but we have a massive file of Manchester City-related documents that has yet to be released."
So he has released them technically and City's lawyers should be able to get hold of them, to see if he's posturing for attention or not.
This is probably what they are going to do if City win the case. Every time someone claims they have evidence that's not been seen before, they'll drag the club's name through the mud again and demand another investigation. If they are allowed to keep doing that, it will be disgrace... clear and organised. There has to be an end to it.
