Everton 1 Manchester United 2
Anthony Martial scored deep into added time to end a late Everton resurgence, and book Manchester United a first FA Cup Final berth since 2007.
It was a stunning late twist to a breathless semi-final in front of a packed Wembley Stadium, where United had led through Marouane Fellaini’s first-half strike, only for a Chris Smalling own goal to throw the momentum back in Everton’s favour after Romelu Lukaku had missed a penalty.
But Martial, lively throughout, showed remarkable calm when put through on goal by substitute Ander Herrera, and sent Louis van Gaal’s side into next month’s Final.
United had lost their previous two semi-finals, including one to Everton in 2011, while the Toffees sported a proud record of having progressed from six of their previous seven.
Van Gaal had kept faith with his rising stars, with Martial, Tim Fosu-Mensah and Marcus Rashford starting, and seasoned campaigners Juan Mata and Morgan Schneiderlin on the bench.
Perhaps the intention was to run at a patched-up Everton defence, where Muhamed Besic was pressed into action at right-back, but United were forced back early on, when Lukaku raced clear on the left.
It was exactly the kind of area where the Belgium striker had ran Chelsea ragged in the quarter final, but his first touch was heavy, and although he lifted the ball over David de Gea, Wayne Rooney was on hand to head off the line.
United hit back though, with Marcos Rojo flashing a header wide from a free-kick and Jesse Lingard forcing a sprawling save from Joel Robles after ghosting through unmarked.
It was a thrilling, open game, and Lukaku had another fine chance, with De Gea blocking at his near post.
United then began a series of forays down their left-hand-side, with Rojo offering a decoy while Martial and Rashford took turns to run at Besic.
The ploy paid off on 34 minutes, when Martial drove into the box and pulled Phil Jagielka across, and while the England defender cleared the ball to an extent, it soon fell back to Martial.
The Frenchman darted towards the byline, and cut back for Marouane Fellaini to score against the club who once paid £15m to bring him to England.
But for all Everton’s struggles, they were given hope on 57 minutes when Fosu-Mensah’s covering tackle on Ross Barkley was adjudged a foul, and a penalty was awarded.
Lukaku stepped up, but although his spot-kick was firmly struck, De Gea dived to his right to pull off a superb save.
Barkley, James McCarthy and Tom Cleverley then all went close for Everton, before United’s rearguard finally gave in with 15 minutes remaining.
The substitute Gerard Deulofeu skipped down the right before crossing dangerously, and while Smalling did well to get to the ball before Lukaku, his touch defeated his own keeper as he sliced the ball into the net.
Lukaku, who had a torrid day until then, pounded the ground with delight.
But any joy for Lukaku and Everton was short-lived.
Herrera, who was booked just seconds after coming on after a professional foul on Barkley, took the ball with his back to goal, and under immense pressure, squeezed a through-ball towards the onrushing Martial.
The Frenchman’s first touch was classy, and his last absolutely deadly.
