Lazio came from behind to win 2-1 away to Fiorentina Saturday in the opening game of the third round of the Italian Serie A, dpa reported.
Lazio drew level with Chievo at the top on six points ahead of Sunday's games, while Fiorentina remained on one and continued a winless run that began last season in late March.
Serb midfielder Adem Ljajic converted a spot kick to score his first goal for the Purples since his arrival in Florence in January, but Cristian Ledesma levelled and Libor Kozak scored a second-half winner.
Ljajic, a promising Serbian midfielder who turns 19 next week, fired home from the spot on 19 minutes after Argentine Ledesma jostled Alessio Cerci.
Ledesma complained about the referee's call and made amends on 31 minutes with a winning volley off a feed from Stefano Mauri.
On another run on the left halfway through the second half, Mauri set up Brazilian Hernanes for a fast shot that French custodian Sebastien Frey managed to stop, finding no help from defenders as Kozak flicked from close range.
