West Ham United

West Ham boss David Moyes to BT Sport: "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.

"At the start we were trying to avoid relegation. The Czech boys have been fantastic for us. You've seen the improvement of Michail Antonio. Declan Rice has come on. Players like Cresswell have improved. Craig Dawson does a great job."

West Ham United

West Ham midfielder Declan Rice to BT Sport: "So special today. This club, the stadium, the fans, the players, we deserve these big European nights. We stepped up.

"We were 1-0 down, we knew Sevilla were such a good team. We knew with our fans and the quality on the pitch we could do it today. It's probably the best night I’ve had at West Ham.

"Yarmolenko was a little bit emotional away from the lads afterwards. For what he's been through to perform like this is a credit to him – his desire, the way he chased players and scored two crucial goals. He deserves this. He stepped up. I’m delighted for him.

"Antonio is massive for us. He’s a focal point. He sucks in two or three player to create space. He’s been unbelievable. He ran his socks off today.

"I’ll take anyone [in the quarters]. There’s no-one to fear. Sevilla were probably the favourites. We can go anywhere and get a result. Teams coming here know they’re in for a game.

"It would be special to go there [Barcelona]. That’s what this club deserves. There's a big buzz around the place.

"David Moyes deserves massive credit.

"I’m lost for words. Walking round the pitch, taking it in. I love West Ham fans. They care so much about this club. They demand 100% and if you do that, they treat you as one of their own. It was special to be on the pitch tonight.

"You can see how much it means to him [Mark Noble]. He’s given everything to this club since he was a little boy. We’re gutted it’s his last season but we want to make it really special for him. What a way to bow out lifting a trophy if that happens.

"The adrenaline Is flowing. I don’t think any of the boys will sleep today. We’ve said 'day off tomorrow?' but the manager has said no."

Sevilla suffered their first ever Uefa Cup/Europa League defeat to an English opponent (P9 W6 D2 L1).

For only the second time in Europe (excluding qualifiers), West Ham went to extra time.

The other was the 1980-81 Cup Winners' Cup first round against Real Madrid Castilla (that's Real's B team).

West Ham United

West Ham striker Michail Antonio to BT Sport: "Unbelievable. This season is like a dream come true. This is the first time in Europe for me. I've become West Ham's Premier League top scorer. We’re just here enjoying our football.

"We dominated. We always believed in ourselves. From the first half we were on them creating chances. [We thought] keep doing what we’re doing and we’d get the win.

"Andriy Yarmolenko is such a lovely guy. I can't imagine what he's going through. He’s got a finishing touch now. Hopefully he can keep doing it.

"I came off Sunday a bit disappointed. Thank God it was a small injury and nothing big and I managed to play 120 tonight. I felt my calf tighten up.

"I've been here seven years and the only atmosphere close to this was the last day at the Boleyn Ground. The fans roared all the way through, backing us. They were the 12th man. I’ll give the win to them, they were the ones who did it for us.

"We fear nobody. We play in the Premier League and it doesn’t matter who we play,we try to get three points. We’re in this to win it. We’re not just here to take part. Why can’t we win it?"

West Ham have reached the quarter-final of a major European competition for the first time since the 1980-81 Cup Winners’ Cup.

West Ham v Barcelona would be the Alex Song derby!

The Europa League quarter-final draw is tomorrow.

West Ham's potential opponents are Atalanta, Rangers, Barcelona, Braga, Eintracht Frankfurt, Lyon and Leipzig.

That was a bad period of extra time for Seville clubs!

An own goal in the 121st minute has knocked Real Betis out. Eintracht Frankfurt go through.

West Ham's Andriy Yarmolenko has played twice since returning from a spell of compassionate leave after the Russian invasion of his native Ukraine - and he has scored in both.

This is the first time he has scored in consecutive games since September 2019.

It's all over. West Ham are into the Europa League quarter-finals!

West Ham have a free-kick now. Surely that's it. Down into the corner.

West Ham have the ball. Maybe a minute left.

Two minutes added on.

West Ham bring on another defender, Ryan Fredericks for Michail Antonio.

West Ham hero Andriy Yarmolenko wins a free-kick and they can eat up the final 30 seconds.

Declan Rice heads away a loose ball just as a Sevilla player is waiting for the ball to drop for a volley.

Final minute.

West Ham clear but they can't shoot into the empty net.
