Well the rumour in itself suggests more than just a player signing then.
As true as this could well be, it does bug me that any potential new manager will only have the option of dealing with what he has and has little choice in the players purchased. If managers have a vision / style / philosophy on how they want to set the team up and how they play, surely they need to have the final say on who is recruited?
As you say, there is nothing concrete in scouting...we probably scout a hundred of players a year only to buy 3, but as I said above, surely our scouts have a remit, a type of player they are looking for or certain attributes that they feel would be key for such a player...but then, how could they if we don't know who will be manager next season or what they are intending to do.
