There are some games which send ripples throughout the world. Manchester City's crushing defeat to Everton on Sunday was one of them.
Pep Guardiola's summary humiliation at Goodison Park was watched with astonishment in his former stomping ground in Germany. In three years at Bayern Munich, the Germans only once saw Guardiola so roundly beaten.
That was in the 4-0 defeat by Real Madrid in the 2014 Champions League semi-final. On that night, Guardiola's Bayern were similarly helpless against a ruthless, counter-attacking team.
On that night, though, it was Real Madrid, not Everton.
