Andriy Yarmolenko was again the hero for West Ham as his extra-time goal knocked out Sevilla and sent the Hammers into the Europa League quarter-finals after a 2-0 victory on the night and 2-1 win on aggregate
It was Yarmolenko's second goal in as many games for West Ham since his return from compassionate leave following the war in his native Ukraine
Trailing 1-0 from the first leg, Tomas Soucek's first-half header brought West Ham level in the tie and while the Hammers controlled much of the second leg at the London Stadium, they could not find the decisive second goal in normal time
Their big moment eventually came in the second half of extra time as Yarmolenko, who came on as an 87th-minute substitute, reacted quickest after goalkeeper Yassine Bounou parried Pablo Fornals' strike to tap home the rebound and spark yet more emotional scenes
The Ukraine international's strike proved to be the decisive goal as West Ham knocked out the six-time winners to book their place in Friday's draw for the last eight as their remarkable European adventure continues
West Ham boss David Moyes told  afterwards: "This will be as high as we've had
 We've had other nights
 Avoiding relegation was an incredible high but thankfully we've moved on from that
"Beating a serial winner of this competition made it a bit more special
 They just keep going
 You could see the resilience in them
 We keep on going
"For the first 20 minutes we were the better side without creating many chances
 They became stronger before half-time
"The message was we knew we had to keep hanging in
 That was more like it tonight
 In the second half our intensity was great until 70 minutes then it dropped off
 We picked up again in extra time and kept at it
 We've not got the trophy yet
 There are still tough games to go
"Nights like this really help you build
 I thought Sevilla were probably the favourites for the tournament
 For us to beat them over two legs is an incredible result
"Yarmolenko had been granted compassionate leave after Russia's invasion of Ukraine and missed West Ham's 1-0 loss in the first leg in Spain due to illness
He reacted sharply to a rebound, however, to send the London club into a European quarter-final for the first time since 1981 and knock out Sevilla, the record six-times winners of the competition
Yarmolenko gave his shirt to a fan with a Ukraine flag as he celebrated a win that started when Soucek headed in Antonio's cross at the far post to put West Ham in front five minutes before half-time
Moyes said he hoped the goal would lift Yarmolenko, adding: "We've all been there where you're losing and you think there's no chance that we're going to get a result
"In football things change for you
 So I hope maybe this changes a little bit of what's in Yarmo's head, maybe what's happening in life
"But overall, if he's getting mentioned worldwide and then everybody else is realising the damage Russia is doing to Ukraine
"After a cagey opening, West Ham needed a stunning one-handed save from Alphonse Areola to keep out Youssef En-Nesyri's powerful strike
The game started to open up and Said Benrahma's brilliantly disguised pass released Antonio, but the striker's shot was palmed away by goalkeeper Bounou before Nemanja Gudelj got to the rebound ahead of Soucek to clear
West Ham got their goal moments later to bring the tie level on the night
 Antonio was involved again, and his inch-perfect cross picked out Soucek, who guided the ball beyond Bounou and into the far corner
After the break, the Hammers went on the attack immediately as they looked to grab a decisive second goal
 Declan Rice set up Soucek, but the midfielder's first-time strike was batted away by Bounou
The tension continued to rise as Manuel Lanzini was denied by Bounou, but chances were becoming few and far between as the game meandered towards extra time
An extra 30 minutes were needed and many home fans thought they'd taken the lead in the tie when Soucek latched onto Dawson's knockdown at the far post
 The net bulged but the crashed into the side netting as a huge chance went begging for Moyes' side
However, then came West Ham and Yarmolenko's moment to spark wild celebrations at the London Stadium
Michail Antonio (10 goals, 10 assists) became only the second player to both score 10+ goals and assist 10+ goals for Premier League clubs in all competitions this season, after Mo Salah (28 goals, 10 assists), while he is the first to do so for West Ham in a single campaign since Dimitri Payet in 2015-16 (12 goals, 15 assists)
Antonio told : "It's been unbelievable
 This season has been like a dream come true
 First time in Europe for me, managed to become West Ham's all-time Premier League goalscorer, and we're just enjoying our football
"We came into the game believing we could dominate
 From the first half, we were onto them, driving and creating chances
 We felt that if we continued playing the way we were, we'd get the win
"Andriy's got the finishing touch right now and I'm so happy for him
 I hope he can keep doing it
"The only atmosphere that compares to this was the final day at the Boleyn Ground
 We came out here and the fans were singing
 The atmosphere was an absolute joke today
 I give the win to the fans
 They were the 12th man so they're the ones who did it for us
