Jarrod Bowen's dramatic 90th-minute goal secured West Ham their first major European trophy since 1965 with a 2-1 win over Fiorentina in the Europa Conference League final on Wednesday.

It is the second European trophy for West Ham after they won the now defunct Cup Winners' Cup 58 years ago with a team including England World Cup heroes Bobby Moore and Geoff Hurst.

Bowen picked up a superb through ball from Lucas Paqueta before sending a low shot past a helpless Pietro Terracciano in the Fiorentina goal.

Said Benrahma had opened the scoring for West Ham in Prague as he blasted a penalty past Terracciano on 62 minutes after VAR had caught Cristiano Biraghi handling the ball while trying to stop Bowen in the box.

Giacomo Bonaventura leveled five minutes later, beating West Ham goalkeeper Alphonse Areola with a fine, low right-footed effort. 

Bonaventura capitalized on a superb header back from Nicolas Gonzalez who had leapt over West Ham full-back Emerson.

The champions' name will be the second ever on the Conference League trophy following Roma, who won the maiden edition of the competition last year.

West Ham have also clinched a spot in next season's Europa League with the win, while Fiorentina will miss out on European competition after finishing eighth in the Serie A.

West Ham's previous major trophy was back in 1980 when they won the FA Cup.

They spent most of the last season battling the prospect of relegation, finishing 14th in the Premier League in the end. 

West Ham manager David Moyes hailed the "incredible" last two years in which his team reached the Europa League semifinal before winning the trophy in Prague.

"Last year we won the group, got to the semi-final, this year we won the group, got unbeaten, now we won the final," said the 60-year-old Scot.

"It's been an incredible achievement to do so well in Europe. I've been really fortunate, I've got a great group of players, I'm with a club who have incredibly supported me."

Fiorentina manager Vincenzo Italiano said it hurt to lose his second final in two weeks after the Viola lost to Inter Milan in the Italian Cup final, also 2-1.

"In the future, we will talk about two disappointments in a single season," he said. "It's a really big blow. I'm upset because we were really close."
