Manchester United were dealt a Premier League reality check by arch-rivals Manchester City in the Premier League, as Pep Guardiola's side ran out 6-3 winners in the 188th Manchester derby.
The Blues ran into a convincing 4-0 lead before the half-time whistle sounded, with both Erling Haaland and Phil Foden each helping themselves to a hat-trick.
Goals from Anthony Martial (2) and Antony eventually helped United reduce the deficit in the second period, but the damage was already done during the first 45 minutes of action.
