Goals from Brayan Perea and Felipe Anderson shepherded SS Lazio through to the UEFA Europa League round of 32, with Legia Warszawa still without a point or a goal in Group J.
The Polish champions struggled to make any impact on a slick Lazio side. Perea headed the visitors in front in the first half, and a neat finish from Felipe Anderson doubled their advantage. Vladimir Petković's team now take on Trabzonspor AŞ on matchday six knowing a win in Rome will put them top of Group J, with a guaranteed home tie in the round of 32 second leg.
Lazio set the pace from the off and went ahead after 24 minutes, Lucas Biglia picking out Perea, who totted up the ball before nodding firmly past Dušan Kuciak in the Legia goal. A decent opportunity was then passed up at the other end, with Vladimer Dvalishvili missing the target from Miroslav Radović's pass.
Perea set up Felipe Anderson early in the second period, but the Brazilian midfielder's effort was comfortably saved by Kuciak. However, he gave the goalkeeper no chance on 57 minutes after Hernanes delivered the ball to his feet, finishing confidently from just inside the box.
Lazio kept pushing for a third and were nearly caught out on 68 minutes when goalkeeper Etrit Berisha's attempted headed clearance presented the ball to Legia substitute Henrik Ojamaa, but he failed to get his shot on target from the corner of the area. An even better opening went begging at the death, with another Berisha mishap offering Radović a sight of goal, but Biglia cleared off the line.
