West Ham United beat AZ Alkmaar on Thursday night in the UEFA Europa Conference League to reach their first European final since 1979.
The Hammers had won the first leg 2-1 at the London Stadium to qualify for the final showdown in Prague, Czech Republic, on June 7.
They scored a 94th-minute winner in the Netherlands to make it 3-1 on aggregate.
David Moyes’ side soaked up plenty of pressure at AFAS Stadium until Pablo Fornals scored on the counter-attack in second-half injury time.
West Ham will face Fiorentina, who beat FC Basel after extra time.
The Hammers are hoping to lift their first major trophy since they lifted the 1980 FA Cup; they were one of three winners of the 1999 Intertoto Cup.
West Ham’s last European final had been in the 1975-76 Cup Winners’ Cup when they lost 4-2 to Anderlecht.
They came agonisingly close to breaking that duck last season, losing 3-1 on aggregate to eventual winners Eintracht Frankfurt in the Europa League semi-finals.
