After a scrappy first-half, United came out the better side and were rewarded when Rashford produced another moment of magic, finding the top corner with his shot.
Fellaini bundled the ball home to double the Reds’ advantage, but it was a nervy finish to the game when James Tomkins headed home, but it proved to be a mere consolation.
United go on to face Everton in the semi-final, but who else shone in the stellar performance?
Stellar performance at the back
David De Gea (8 out of 10) – The Spaniard proved to the rest of the world why he is the best goalkeeper in the Premier League, a solid performance as he looked comfortable throughout, and the save from Antonio’s effort was sublime.
Timothy Fosu-Mensah (7 out of 10) – The youngster will have Matteo Darmian out of the side soon, as the Dutchman has been thoroughly impressive since bursting onto the scene. Another promising display and he seemed to control the unstoppable force that is Dimitri Payet.
Chris Smalling (6 out of 10) – Smalling had the challenge of marking Andy Carroll all evening, and he certainly didn’t do a bad job either. Seemed to make the most of his duel, however, he did lose Tomkins, who went on to head home and reduce the deficit.
Daley Blind (6 out of 10) – The Dutchman always seems content and never looks flustered despite the situation of the game. A collected display once again, and seemed to have more time on the ball throughout the evening.
Marcos Rojo (5 out of 10) – Rojo picked up a needless yellow card in the game, and was also guilty of making silly fouls throughout the evening. Since his injury, question marks have been above his head, and he needs to start performing.
Solid display in the middle of the park
Michael Carrick (6 out of 10) – Back in his normal position, Carrick seemed to be off the pace at times during the game, and also failed to cope with West Ham’s nature going forward. However, he did look resilient as ever in the centre of the park.
Marouane Fellaini (7 out of 10) – Questions have been asked of the Belgian as of late, but a stellar performance at Upton Park has silenced some doubters. He made a nuisance of himself all evening and his driving runs forward was rewarded when he bundled home United’s second.
Ander Herrera (6 out of 10) – Herrera was forced off midway during the second-half, but he was also fortunate enough not to have been sent off for a second bookable offence. Just like Carrick and Fellaini, he passed the ball well and also joined in going forward.
Front three dynamic as ever
Jesse Lingard (6 out of 10) – Lingard missed a brilliant chance in the first-half when he struck his effort straight at the keeper. The youngster made plenty of runs going forward, but at times his service into the danger area wasn’t to his usual standard.
Anthony Martial (6 out of 10) – The Frenchman proved to be his best when he came inside from the wing, and his partnership with Rashford is going from strength to strength. Claimed two assists during the game and United’s future up top looks bright.
Marcus Rashford (8 out of 10) – Who is going to stop this youngster? Rashford has burst onto the scene and showed everybody exactly what he is made of. He made many encouraging link-ups with Martial and Lingard and also got his goal when he produced a moment of magic once again.
