The Red Devils beat West Ham United 2-1 at Upton Park on Wednesday night to book a semi-final spot.
Manchester United might have finally found a shining light in an otherwise underwhelming season in the form of their FA Cup campaign, as Louis van Gaal's side booked a semi-final clash against Everton at Wembley next month with a 2-1 win over West Ham United in the quarter-final replay at Upton Park on Wednesday night.
Coming into the match, many pundits had the Hammers down as favourites after United were taken apart by Tottenham Hotspur in a 3-0 defeat on Sunday.
However, after a nip-and-tuck first half lacking a moment of serious quality to light the fuse, that spark arrived nine minutes into the second half when Marcus Rashford opened the scoring in style, collecting the ball in the penalty area before shimmying past his man and curling into the far corner.
United doubled their lead 13 minutes later thanks to the knee of much-maligned midfielder Marouane Fellaini, who had looked in fine form from the first whistle, and though James Tomkins headed one back late on, it was the visitors who booked their spot at Wembley.
Rashford, who was impressive throughout, took his tally for the season to six goals from 11 appearances since making his senior debut at the end of February.
Meanwhile, fellow 18-year-old Timothy Fosu-Mensah put in another sterling performance in a defensive role, showing why Van Gaal has placed such trust in him in recent weeks.
After the match, the teenage pair came in for particular praise from United fans on Twitter who were quick to hail the pair as the brightest stars of the club's future.
£250m spent and LVG's best is an 18 year old. Remember the name Rashford. I'm sure we'll be hearing it a lot more for hears to come. #MUFC— Schweinsteiger (@ManUtdDevilNews) April 13, 2016
Rashford and Fosu-Mensah brilliant again. There might be something in this giving kids a chance thing after all— jb8521 (@jb_8521) April 13, 2016
Fosu-Mensah colossal, and that finish from Rashford?? Wow. Exciting to watch those two and Lingard play in triangles #MUFC— Wigg (@WIGGy_muFc) April 13, 2016
Our best 2 players today are 18! What a goal from Rashford and sick defending from Mensah. They make me feel so old #WestHamVsManutd— Raheem Rafiq (@_Raheem96) April 13, 2016

De Gea and Rashford obviously outstanding, but Fosu-Mensah is getting better by the game. Top prospect— GazHiggy (@GazHigg) April 13, 2016
The two young lads, Rashford and Fosu-Mensah, were superb tonight. They've added so much energy and pace to the team— JC (@JustCantona) April 13, 2016
The quality and maturity of Rashford's play also led to more England fans than ever calling for the youngster to be taken to Euro 2016, even if only as a wildcard akin to Theo Walcott's inclusion for the 2006 World Cup.
People saying Rashford still has a lot to learn. I think he'll learn a lot,going to the Euros as England's wildcard. #bbcfacup— Mufc Believer (@MR_LAMIDE) April 13, 2016
Rashford should be in the Euros too. He should learn from the bench— McXZero (@AtolagbeOA) April 13, 2016
Needs to be said time and time again. National side should be form based. Rashford might not start at the euros but...— Matthew (@mattyhew96) April 13, 2016
Would love hodgson to take a gamble and take rashford to the euros what a player— Ryan Richardson (@Ryan96R) April 13, 2016
Genuinely think that we should take Rashford to the Euros to mix things up a bit, I reckon it would be a good decision ⚽️— Jake (@jakey_gilbert) April 13, 2016
Rashford needs to go to euros tbh, he's a quality young player, which England are lacking in.— Jake (@ClassicConte) April 13, 2016
Honestly consider taking Rashford as last striker to euros. Could have an impact coming off bench he makes things happen— Tyler (@tylersaxton93) April 4, 2016
GET RASHFORD TO THE EUROS— Dan Burgess (@Dannburgess) April 13, 2016
