The 19th century Russian writer Alexander Herzen said revolution is invariably frightening, as "the departing world leaves behind it not an heir, but a pregnant widow." The old order is not simply flipped. Before the birth of any new regime, "a long night of chaos and desolation will pass," with the cries of a baby only heard after a nine-month trimester.
In more prosaic terms, nothing changes overnight. There will be fallow periods before the crop.
Talk of revolution is not uncommon in football; patience most certainly is. It is impossible to have one without the other.
