It's hardly baseless speculation. Technical Directors/Directors of Football are supposed to be responsible for transfers. Unless we're paying this guy to do nothing, I remain convinced that every single signing since summer 2011 has been done exclusively by Mad Mike. Typically a manager gets little say when working under a TD/DoF, all they do is tell their superior what position they want strengthened. It is then up to the TD to decide which player fits that bill, and they can ignore the managers request if they feel like it. Of course all of the above still is speculation, but it's not entirely baseless, given on knowledge known from how continental sides operate with their TD's.
