Now the wild celebrations have subsided, Manchester United must get their head back in the game.
Wednesday will see United travel to London for the first of two trips to the capital this week to take on Crystal Palace, a fixture initially scheduled for September but rearranged with just two weeks' notice. While increasing the workload on an already hectic January, the fixture has given Erik ten Hag's side the chance to move above Manchester City for the first time in years. For a day at least.
It's a massive chance to deal another blow to their neighbours. City are in action on Thursday against Tottenham. Though Antonio Conte's rabble are in freefall, Spurs are the Blues' bogey team and often win when all logic dictates they should lose.
