It was almost an hour after the end of the game on Tuesday night when the door in the corner of the Sunderland press room opened and Sir Alex Ferguson walked in, preoccupied with buttoning his coat and following the official leading him out of the stadium. When the old boy clocked where he was, his face set to stony non-engagement and he was quickly across the room and out.
The journey home to Cheshire, if he was heading back immediately, will have topped two hours and the weather was cold enough for his travelling companion Sir Bobby Charlton to be wearing his big winter hat. For a multimillionaire retiree who has spent his life working relentlessly, one would have assumed Ferguson would be more tempted by the Caribbean in January than Tuesday evenings at the Stadium of Light.
It posed that old question: why is Ferguson now turning up for United away games as well as those at Old Trafford? And if he cannot see that his presence is diminishing David Moyes as the new man wrestles with a nightmarish run of results and form, then is it about time that someone told him?
No one would doubt that Ferguson is among that group of individuals who have done more for United in their 136-year history than any other. He has the right to be at every United game for the rest of his life. But having the right to be there, and it being the right thing to do, are two very separate things. Especially for a manager who knows better than anyone how these things play out.
After every goal conceded by Moyes' team, every setback, and then in the aftermath of every defeat, the cameras pan to Ferguson and his poker face. It may not be fair and it is not the Scot directing the television coverage, but it is the way it has always been. Ferguson knows that all football matches follow a narrative - and that narrative is about more than what takes place on the pitch.
