The Italian side was humbled in the first leg as Sevilla recorded a comfortable 3-0 victory at home. Aleix Vidal scored a brace and Gameiro got himself on the score sheet as well as Unai Emery's men carry with themselves a healthy advantage to the second leg.
However Sevilla's manager has refused to get carried away and has insisted that his team will have to finish the job in the return leg. He alluded to Los Rojiblancos' encounter with Valencia in a similar stage last season when his side were beaten 3-1 in the second leg but were able to advance to the next round of the tournament courtesy of an away goal advantage.
“Our semi-final against Valencia last year serves as a great example because they nearly turned the tie around,” Emery said
"We have to play a good game, and a good game comes when you play to win."
"I can't guarantee that we will be [in the final]. All I can guarantee is that we will give it our all to get there.
"We may have beaten them in first leg, but we can't take it for granted that we'll beat them again."
Vidal on the other hand who was deployed in an unconventional right back role expressed his content over his performance in the first leg and is confident his team can make it to the final.
"Personally, I thought I played really well, but it's difficult to do so without the help of my team-mates," the Spaniard said.
"I always want to get better and moments like this are a chance to gain confidence and keep going.
"I'm not a defender, I try to do the best in my position and I'm improving myself. We knew it would be so hard to qualify for two consecutive finals, but we are having a spectacular season and we will try to reach the final in Warsaw."
Fiorentina on the other hand have suffered three defeats in their last five matches and will be short on confidence when they face the Spanish side on Thursday. They however did pick a 3-2 win over Empoli last time out and will be hoping they can give Sevilla a run for their money.
Sevilla goalkeeper Beto has travelled with the squad despite suffering from a shoulder problem, however Dani Parejo (knee) has been ruled out of the match.
Fiorentina meanwhile will be without the likes of Micah Richard (hamstring), Manuel Vargas (adductor) and Nenad Tomovic (hip)
