It was as sweet a strike as you could wish to see, but Pep Guardiola was not interested in celebrating the Riyad Mahrez free kick that began this rout.
He was calling 20-year-old Cole Palmer over and giving him an animated in-game tutorial that included a ticking-off for not plating up a golden chance for Julian Alvarez. Pep keeps taking perfectionism to new levels.
This was not just about Manchester City swaggering into the FA Cup fourth round, this was about Manchester City reminding football that Guardiola has assembled and shaped a squad that is as formidable as any the English game has seen.
