Manchester United progressed to the FA Cup semi-finals on a disappointing night at the Boelyn Ground. Marcus Rashford and Marouane Fellaini were on hand to spoil the party, despite a late goal from James Tomkins and a disallowed effort from Cheikou Kouyate.
It was a disappointing night for the Slaven Bilic's men in what was the final ever FA Cup match to be hosted at Upton Park before the move to the Olympic Stadium over the summer.
Strong perfomances in paticular from Mark Noble, Angelo Ogbonna and Darren Randolph weren't enough as the home side overall played well below the standard they have been producing this season.
Louis van Gaal's side can now look forward to a date at Wembley in 10 days time with Everton.
Tame first half
The atmosphere was electic inside the ground before kick off and this seemed to spur the Hammers on in the early encounters, with Enner Valencia delivering a tame effort on David de Gea's goal after some nice work from Manuel Lanzini. An early Dimitri Payet free-kick was also delivered on target but again was easy for the Spanish keeper to collect.
West Ham United's Darren Randolph produced a first half save of his own, brilliantly denying Fellani after his shot took a minor deflection off of Angelo Ogbonna. The Republic of Ireland stopper produced fantastic reactions in tipping the effort over the bar despite the ball moving unkindly to him.
Valencia would have another soft attempt on goal after getting in behind the away defence, but ultimately was unable to capitalise on the chances when they fell to him. Andy Carroll was unable to replicate his fine performance at the weekend against Arsenal as he struggled to link up with the likes of Lanzini and Payet.
Visitors take control
The Red Devils started the second half on the front foot with Jesse Lingard seeing his 20 yard strike swerve the wrong side of the post. The England youth international found space on the edge of the box but was unable to hit the target as the away side began to take control of the game.
United's second half dominance paid off in the 53rd minute, as Michail Antonio's unforced error gifted the ball to Anthony Martial deep in the West Ham half. The Frenchman was able to pick out Rashford, who dipped a shoulder and superbly curled an effort into the top corner in-front of the away end. A fantastic goal from the much hyped about English youngster.
United went on to double their lead with 67 minutes played after Lingard and Martial linked up and Fellani converted from close range. The West Ham defence switched off for a matter of seconds and were punished in giving Fellani too much space in the box. The Belgium international saw Martial's pass bounce off his knee and in between Randolph and Aaron Cresswell on the line.
Too little too late
Bilic then introduced Victor Moses and Emmanuel Emenike to the action, with Moses having the greater impact. The Nigerian was able to stretch the game further and made a nuisance of himself in the later stages of the game.
The Hammers would have to wait until the 78th minute for their best opportunity, as Antonio met Payet's corner at the near post only to be denied by a brilliant save from de Gea. United's player of the season without any doubt.
The resulting corner, however, delivered the Hammers' consolation, with Carroll rising highest to nod across the box to Tomkins. The academy graduate headed bravely into the net and from that point on a late fight back seemed on the cards.
The Hammers threw everything at United's goal over the next 10 minutes. Carroll headed over after a fantastic delivery from Cresswell, a chance you'd expect him to at the very least work the keeper with.
The away side had their keeper to thank at the death as de Gea denied both Kouyate and Carroll's efforts before Kouyate headed in a rebound. Replays showed that the Senegal international was indeed offside, much to the delight of the travelling away support as the linesman's flag went up.
A tough result to take for West Ham as they bow out of the FA Cup at this late stage on what was meant to be a fairytale way to end their final season at Upton Park. The Cockney boys still remain in the hunt for the UEFA Champions League places, sitting five points off Manchester City in fourth, which is something considering this season was solely based on gaining Premier League survival.
In spite of this lacklustre display, the Hammers can now focus their attention on travelling to the league leaders Leicester City on Sunday, as they look to confirm European football for themselves in the Olympic Stadium next season.
