All the story says is the Juvé scout apparently praised the Newport scout for his dossier (that everyone has already read), and now he's dining off it (the quote is his, there's no quote from anyone at Juvé)
So if that's Juvé asking for the dossier… well… Whatever, half the team won't play against Juvé anyway.
This is all a plot from the start. Pochettino leaked the dossier to the press under false identity, hoping that Juventus would read it thoroughly. Now, Pochettino is spending all the time in his little tactics laboratory (pronounced la-BOH-ra-tory, not labrador-y) to come up with a shocker of a scheme that will leave all of Torino barren and wasted.
This says more about the quality of football journalism in the UK. These documents are standard across the profession and only vary by the level of detail required by the manager. If journalists worked on improving their tactical understanding of the game they would be more privy to this insight.
Data analysis is also shared on a regular basis between clubs through Opta, Pro Zone, InStat, etc. There are no secrets as to what teams try to do. It is how you use the data and whether you are successful in doing so.
If I was playing City tomorrow I would consider pressing their back four, overloading Walker, getting runners in between the centre backs and denying service into DeBruyne. Implementing those ideas and getting a result at City are two totally different things entirely.
Credit Newport for the start they made to the reply, but after 10 minutes they had no Plan B.
