Pep Guardiola says Manchester City's 20-match winning streak is 'one of the greatest achievements in our careers' - but is it merely a step towards becoming the first side to complete the quadruple?
The 2-1 win against West Ham was Guardiola's 200th victory in 273 games as City manager. No-one has reached their top-flight double century in England in fewer games.
City have not dropped a point since 15 December, they have not lost since 21 November. Michail Antonio's equaliser was the first goal they have conceded to an opposition player in open play at Etihad Stadium in the Premier League since James Maddison curled in a 25-yard effort for Leicester on 27 September.
