It is coming up for two years since Pep Guardiola's managerial nadir, a night Manchester City were humiliated in Monaco. You tend to learn a great deal about personalities in those moments and, for all the talk about styles of play, he shone a light on his true focus in the immediate aftermath.
He referenced his trophy haul from Barca and Bayern with a touch of ego. Guardiola is a genius, a tactician above all others, but he is also the ultimate 'show us your medals' manager.
'I think exceptional other managers in the world sometimes don't win titles in a season,' he said in the face of stinging criticism after Champions League elimination.
