Sir Alex's matchday office at Old Trafford is deep in the bowels of the stadium, and only a select few are ever permitted to go inside…
Not even the award-winning Museum and Stadium Tour enters the manager's office. In use only on matchdays, this is Sir Alex's sanctuary, a place where he can plot tactics before the game and unwind after it.
It's here where, famously, the manager shares a bottle of wine with the opposition boss among other special guests, family and friends. A selection of refreshments are available and a television ensures Sir Alex stays up-to-date with any other matches taking place.
Football isn't always the topic on everybody's lips, however. In fact, we're told it's often completely unrelated subjects – the manager has a keen interest in film, politics and horse racing, for instance – that dominate discussions.
