Frenetic derby was just the place for the interim manager to roll out Ferguson’s old ‘use the energy of the people’ dictum

For Manchester United’s executives, City are the best-in-class runaway train they wish to emulate and aspire to. Coveted talent like Antoine Semenyo and now Marc Guéhi opt for blue when a generation ago, Old Trafford was the destination of dreams.

United’s myth and legend becomes increasingly sepia-tinged but there may be life in it yet. The list of Sir Alex Ferguson’s boys able to take the reins in times of emergency is being exhausted but Michael Carrick, on his second turn, found a way to feed off it. He has just 17 games though there is a tantalising prize on offer. A return to the Champions League looks possible. Rather than embracing the void, Carrick’s United reminded that sporting directors, analytic departments and strategic reviews may have their place in the eventual restoration of power, but dogged spirit, wanting it more, can win the day.
