Don't know but I saw Keith flick through the tactical bits of the document in the technical area on Tuesday night just before the late substitutions which led to the goal.
I did notice the club had a sly dig at the document when they tweeted the footage of Powell's goal as well. Clearly been seen within the club, no doubt it will have rattled a few cages. I'm sure a lot of people will have a view on whether that is good or bad!
