As someone mentioned earlier, it is common practice for organisations to leak information that helps them acheive their goals. But they will have controls and relationships with particular contacts or journalists who will operate on their behalf. Anyone that is unknown to them that is leaking information which undermines the clubs business needs to be either asked to stop, or to be controlled. Good point about the squad info though, but as I've read recently, you can usually guess the lineups from who is wearing which bib in training.
