Erik ten Hag insisted there would be no hangover following Manchester United's Carabao Cup final triumph.
And although they left it late, until the 90th minute in fact, United ultimately proved their manager right, to advance to the quarter-finals and keep their Quadruple dream alive. United's match-winner was 18-year-old sensation Alejandro Garancho, whose curling effort just as added and extra-time beckoned, sealed the win for Ten Hag's side.
The Red Devils looked to be heading for defeat, after Said Benrahma gave West Ham the lead after the break, but an own goal, Garnacho's late strike and another from Fred in added time sealed the comeback win.
