Tonight's win in Poland followed a 4-1 victory in Seville last week, and the Spanish side were equally comfortable in the second leg.
The visitors took the lead after 22 minutes thanks to a thumping long-range effort from Ivan Rakitic.
It took Sevilla until deep into the second half to add to their lead further. Jairo scoring himself this time after finding space in the Wroclaw penalty area.
The Spaniards were not finished there though, and added a fourth with just over 10 minutes remaining. Jairo was again involved, pressing the home defence, collecting the ball and squaring it for Diego Perotti to make it 4-0.
Then, in the final few minutes, Bacca doubled his tally after finding more gaps in the Polish side's defence.
