After a 1-1 draw at Old Trafford, West Ham and Manchester United met in an FA Cup replay at Upton Park, with many believing that Slaven Bilic's men would come out on top.
However, that's not what happened as teenage striker Marcus Rashford scored a stunning opener for United, before Marouane Fellaini bundled the ball home from close range to make it 2-0.
West Ham did get back into the game with James Tomkins heading home, and despite having the majority of possession after that 79th minute, they couldn't land an equaliser.
It was certainly a disappointing evening for West Ham, who played their final ever FA Cup tie at Upton Park. Players like Manuel Lanzini and Dimitri Payet failed to really get into the game, and the whole team appeared to be flat right up until Tomkins' goal.
After the game, former West Ham midfielder and current BBC pundit Trevor Sinclair took to Twitter to suggest that the Hammers didn't even turn up for the first hour, and United deserved the win, which sends them into the FA Cup semi-final.
Sinclair also claimed that West Ham will now need a big effort to get themselves up for this weekend's Premier League clash with Premier League leaders Leicester City, where the Hammers will be hoping to end a run of three straight league draws.
