Lazio battled from a goal down to draw 1-1 at Sparta Prague in the first leg of their last-16 Europa League tie, with an away goal from Marco Parolo giving the Serie A side the edge.
Sparta took the lead after just 11 minutes when Martin Frydek smashed a rising drive into the top-left corner from 14 yards.
Lazio equalized seven minutes before halftime as Parolo turned in the loose ball after Wesley Hoedt's header was parried by Sparta goalkeeper David Bicik.
Antonio Candreva hit the crossbar with a stunning volley as the visitors looked the more likely side to go on and win the match, but Lazio will be content with a draw.
