Sevilla stayed on course for a third straight Europa League title by claiming a 2-2 draw against Shakhtar Donetsk in Ukraine in the first leg of their semi-final.
Unai Emery's side are looking to become the first to win a major European competition three years in a row since Bayern Munich 40 years ago.
They had to come from behind after Vitolo's early goal was cancelled out by Marlos and Taras Stepanenko, with Kevin Gameiro's late penalty giving them two vital away goals.
And, given their superb home record, Sevilla will fancy their chances of reaching yet another final.
The contrast between Emery's team at home and away is remarkable, with Sevilla managing just one win on their travels in Europe and none in the Primera Division.
But it took only six minutes for the Spaniards to take the lead in Lviv. Gameiro released Vitolo and he was allowed to turn inside by Yaroslav Rakitskiy before finding the net.
