Lazio maintained their best start to a Serie A season since 1975 with a comfortable home win over Siena this afternoon.

Vladimir Petkovic's side were forced to start without Brazilian playmaker Hernanes after he failed a fitness test prior to kickoff.

His replacement Ederson took the opportunity to start by opening the scoring on 18 minutes, after he latched onto an Antonio Candreva corner.

Ederson further endeared himself to the Lazio faithful by copying the club's mascot Olimpia with a flying eagle celebration.

The home side were two goals up shortly after when they were awarded a penalty for Gianluca Pegolo's trip on Miroslav Klose.

The German international left penatly duties to Cristian Ledesma, and he made no mistake with an assured finish.

Siena found a consolation in injury time through Alessio Sestu to ensure a nervy finale, but it was Lazio who held on to claim all three points.
