In the 30th minute, Josip Ilicic cut back in the box and drew the foul, then coolly placed the penalty right down the middle to give Fiorentina the lead.
2 minutes before halftime, Nikola Kalinic doubled the advantage by latching onto a long ball and, after some shambolic defending, rounded the keeper and slotted home.
Borja Valero played a pass to Sebastian Cristoforo in the 73rd minute which the Uruguyan lashed into the bottom corner for his first-ever Fiorentina goal.
The Viola never really looked like conceding, and never really got out of 3rd gear going forward; basically, they made Slovan Liberec look like minnows. This is not a bad thing.
