Manchester United beat West Ham United 3-1 in the FA Cup Round of 16, taking the Red Devils to just one defeat in 20 home H2Hs against the Hammers since 2007.
After ending their longest trophy drought since the 1980s, the Red Devils showed off the Carabao Cup before kick-off but seemed to be suffering a cup final hangover rather than being boosted by it.
The hosts were then given a scare when Saïd Benrahma played Michail Antonio through on goal, although the striker was closed down by David de Gea and Tomáš Souček headed into the side netting from the ensuing corner.
The hosts completely stopped thinking Souček had allowed the ball to run out of play while West Ham played on and Emerson Palmieri found Benrahma, who rifled his strike into the top corner.
Lisandro Martínez and Marcus Rashford were immediately brought on, but it was Antonio who had another big opportunity and once again saw his effort saved.
Man United got their reward in the 90th minute, with Garnacho cutting in to put the Red Devils ahead, before Fred’s goal in the final moments added an extra layer of gloss as they progressed in the FA Cup with their unbeaten run at home stretching into its 19th match and their quadruple hopes remaining intact.
