Pep Guardiola says his sleep has suffered during Manchester City's deepening crisis, so he will not be helped by a nightmarish conclusion to one of the most stunning defeats of his long reign.
Guardiola looked agitated, animated and on edge even after City led the Manchester derby through Josko Gvardiol's 36th-minute header, his reaction to the goal one of almost disdain that it came via a deflected cross as opposed to in his purist style.
He sat alone with his eyes closed sipping from a water bottle before the resumption of the second half, then was denied even the respite of victory when Manchester United gave this largely dismal derby a dramatic conclusion it barely deserved with a remarkable late comeback.
