(CNN) -- Lazio drew level on points with reigning champions Inter Milan at the top of Serie A after a 1-0 win at Chievo on Sunday.
A second half goal from Argentine striker Mauro Zarate gave the Rome side a valuable three points and ended Chievo's hopes of taking over at the top.
Zarate had missed a similar chance earlier in the match but kept his nerve to beat Stefano Sorrentino from close range.
Ironically, Lazio benefit from the 1-0 win over Inter of their bitter city rivals Roma on Saturday night, the first league defeat of the season for new coach Rafael Benitez. Mirko Vucinic headed a stoppage time winner.
"It can happen that you concede a late goal but we just didn't play with enough intensity," Benitez told AFP.
Chievo stay third after missing a rare chance to go top while promoted Brescia also wasted their opportunity to hit the heights after a 2-1 defeat Sunday at Bari.
Emanuel Rivas and a penalty from Brazilian Barreto sunk Brescia, who scored through Panagiotis Kone.
In other Sunday Serie A action, Fiorentina beat Parma 2-0 to pick up their first win of the season while Udinese secured a goalless draw at Sampdoria, but stay bottom.
Juventus, humbled at home by Palermo in midweek, recovered superbly with a 4-2 win over Cagliari in the late match, with a hat-trick from Milos Krasic, to lift themselves into mid-table.
In Spain's La Liga, Espanyol kept their 100 per cent home record with a 1-0 win over 10-man Osasuna.
Osasuna had defender Manuel Lolo red carded after 21 minutes and fell behind to the only goal of the match soon afterwards as Alvaro Vazquez scored.
The victory moves Espanyol up to fifth in the standings, just ahead of Sevilla, who were beaten 2-0 by Hercules, with new signing David Trezeguet scoring both goals.
