Manchester City’s Premier League title challenge took a major blow on Saturday after being thrashed 4-0 at home by Tottenham. The four-time defending champion conceded two goals in the opening 20 minutes at the Etihad Stadium and twice more after the break to extend its losing run to five games in all competitions.

If the first scarcely left City distraught, with Guardiola unworried by exiting the Carabao Cup, the latest was more emphatic, more dramatic, more chastening, more stunning. Guardiola’s joint heaviest defeat became an embarrassment.
