David de Gea's missed penalty consigned Manchester United to a dramatic 11-10 penalty shootout defeat against Villarreal in the Europa League final following a 1-1 draw in Gdansk, Poland
This felt a huge missed opportunity for Ole Gunnar Solskjaer as a first trophy as Manchester United manager continues to evade him
 In front of 9,500 supporters, Gerard Moreno met Daniel Parejo's free-kick to steer home his 30th goal in all competitions to give the Spanish side a first-half lead (29)
United, who won the competition under Jose Mourinho in 2017, were indebted once again to the razor-sharp finishing of Edinson Cavani, who struck his 16th goal in his last 11 Europa League starts to haul his side level (55)
It was one of just two shots on target from United as extra time failed to illuminate a poor contest, but goalkeeper Geronimo Rulli would prove the hero during a pulsating shootout, first converting his own penalty before keeping out De Gea's effort as Unai Emery clinched a fourth Europa League title and Villarreal a first ever major trophy
Villarreal finished seventh in La Liga and were facing the prospect of playing in the Europa Conference League next season had they become the first Spanish team to lose a European final against a non-Spanish side in 16 previous showdowns
Monaco stood to benefit with a Champions League group stage berth via the back door had United prevailed
 But Emery would be reunited with his favourite trophy with a place at Europe's top table to boot
Having famously struck with virtually the last kick against Bayern Munich to win the Champions League for United on this day in 1999, Solskjaer spoke about the pressure and expectation to claim his first piece of silverware as United boss, 22 years on from that fateful night, but he conceded afterwards that his players "didn't turn up"
Villarreal arrived in Gdansk unbeaten in their 14 Europa League matches, winning 12, while it was 20 years ago that an English side vanquished an opponent from La Liga in a European final - losing all nine previous meetings dating back to Liverpool's UEFA Cup triumph over Alaves in 2001
Sir Alex Ferguson sat watching on from the stands at the Polsat Plus Arena
 As did Wayne Rooney, the last United captain to lift a trophy, and they would have been encouraged by the start
Marcus Rashford, one of just two survivors from the United side that beat Ajax in the final four years ago, teed up Scott McTominay for an early shot from the edge of the box but he dragged his effort well wide
Solskjaer's men had already knocked out two Spanish sides - Real Sociedad and Granada - en route to the final, and Villarreal were struggling to get out of their own half in the opening quarter of an hour
Emery, who won the Europa League three times in a row with Sevilla, continued to look agitated as Luke Shaw collected Aaron Wan-Bissaka's cross with his fizzed shot just evading the studs of Bruno Fernandes
Villarreal absorbed the early threat and began to impose themselves via a spate of Daniel Parejo corners
 On one such occasion when United failed to clear, Carlos Bacca's dexterous rabona cross was headed over Pau Torres
Emery had shown no hesitation in calling on Yeremi Pino; aged 18 years and 218 days, he became the youngest ever Spanish player to start a major European final, breaking the previous record held by Iker Casillas, and he fired a warning sign with a snapshot moments before United fell behind
Moreno hung on Shaw's shoulder before his darting run inside pinned Victor Lindelof as the striker stuck out a leg to meet Parejo's free-kick and stab his shot beyond De Gea at the far post
 It was his 82nd goal in all competitions for Villarreal, joining Giuseppe Rossi as the club's all-time top-scorer
The inquest began into United's slack defending as Solskjaer stepped out from his technical area, a forlorn figure with his arms outstretched
 He berated an increasingly dispiriting opening period which very nearly had a happy ending as Mason Greenwood escaped Alfonso Pedraza down the right with his firm cross deflecting off Raul Albiol into the grateful arms of Rulli
A hallmark of United's season had been overcoming setbacks; collecting an unrivalled 31 points from losing positions in the Premier League, and Solskjaer called on his players to show their resolve once more having produced a measly xG of 0
09 before the restart
Villarreal had only conceded two goals away from home in the competition, however, and threatened a second on 48 minutes as a slip by Eric Bailly very nearly allowed Moreno to scramble the ball home from close range
 Nick Wright commented: "Another set piece causes mayhem in the Manchester United box
 They are missing Harry Maguire, undoubtedly, but defending set pieces has been a problem for this side all season
"Villarreal had clearly done their homework, as they survived a faint penalty appeal and a VAR check when Greenwood went down holding his foot following a challenge from Pedraza
 There was more intensity to United's play, and they would draw level on 55 minutes
Shaw's corner was cleared only as far as Marcus Rashford, whose mishit ricocheted kindly for Cavani to instinctively finish
 Once more, referee Clement Turpin consulted VAR Francois Letexier for offside, but the goal stood
Cavani had done extremely well to get back onside as yellow shirts flooded out of the box, and United went in search of an instant second as Fernandes struck a loose ball across goal, flashing inches away from the predatory Cavani
Villarreal were beginning to tire as Rashford scuffed a glorious chance wide of Rulli's post from Fernandes' cross on 70 minutes, although the linesman's flag spared the Englishman's blushes, with Torres then in the right place to block Cavani's improvised header from Shaw's wayward shot
Villarreal's second-half forays were sporadic with Moreno missing the target from distance - their first attempt since the break to United's six
 The momentum was with United as McTominay drove them forward in search of a winner, feeding Shaw down the left before his cross was headed over by Paul Pogba
But if Villarreal were braced for a late onslaught, it never materialised as United slunk back into risk-free football
 Instead, Torres failed to bend his shot from Mario Gaspar's cut-back inside the post as Turpin signalled for extra time
Emery had made five alterations up until this point while Solskjaer still had all five of his substitutes to call upon
 It felt somewhat strange given the dip in intensity of the opening 15 minutes of additional time as one of those Villarreal reinforcements, former Liverpool defender Alberto Moreno, sliced a shot wide from the angle
The game was developing into a war of attrition, with Paco Alcacer's rushed finish the last act before Fred was introduced for the fading Greenwood
 The momentum had shifted back to Emery's men but with their opponents subdued, penalties felt an inevitability
United had experienced just why Villarreal had gone the whole competition unbeaten; the last time the Europa League was decided by a shootout was back in 2014, when Emery was manager of Sevilla - overcoming Benfica 4-2 following a goalless draw
De Gea hadn't saved a Premier League penalty for six-and-a-half years, and he didn't come close to keeping out any of Villarreal's efforts in a nerve-shredding shootout that was decided in dramatic circumstances as following 20 successful spot-kicks, Rulli blasted home his penalty before denying the crestfallen De Gea
Manchester United boss  told : "It's quiet, of course, it's a disappointed dressing room
"That's football for you
 Sometimes it's decided on one kick - that's the difference between winning and losing sometimes
 We've got to learn from that one, got to not savour this feeling, but taste this feeling and make sure you don't get it again
"We didn't turn up and we didn't play as well as we know we can do
 I thought we started alright and they scored from the only shot they had on target
 We pushed and pressed, but after we scored, we couldn't control the game as well as we'd have wanted
"They made it hard for us and closed the spaces
 They defended well and we didn't create enough big chances
 Now is not the time to point the finger at what I'd have done differently but when you come away without a trophy, you've not done everything right
"We're getting closer and closer
 We were one kick away from getting the trophy and having a good night
 We have to show the desire to improve and get better next year
 No [it's not been a successful season]
 We have to get better
 They're gutted in there but now is not the time to analyse the whole season
"Villarreal boss : "My fourth Europa League success is no secret
 It is all about work
 Nothing else
 For example, in the last week I have analysed 17 United games
 Then the players have shown great character throughout not only the competition in general but also in the final
 They have been fabulous
"As for the penalties, we did not practise or rehearse them
 It is something which happens in the moment, that's all
 In the end it turned out well for us
"I think the players have shown a good mentality throughout the competition and in the final
