MILAN: A controversial Mauro Zarate goal helped Lazio recover from two straight defeats with a 2-0 home win over Napoli Sunday which sent them back to the top of Serie A pending the Milan derby later. Edy Reja's side had lost last weekend's city derby with AS Roma and the midweek game at promoted Cesena but were quickly back to their best. Argentine Zarate appeared to use an arm when he grabbed the opener on 15 minutes before fellow striker Sergio Floccari doubled the lead in the second half from a Zarate assist. Sampdoria drew 0-0 with Chievo to slip to 10th after again missing the influence of forward Antonio Cassano. Argentina playmaker Javier Pastore increased his burgeoning worth with three goals in seventh-placed Palermo's 3-1 win over Catania in the Sicilian derby. Early season strugglers Udinese continued their surge up the table and are level with Palermo and Genoa, who won 1-0 at Cagliari, after last term's league top scorer Antonio Di Natale bagged a first half hat-trick in a 4-0 home romp over Lecce. Bari stayed bottom after a 1-0 home loss to improving Parma while Bologna overcame promoted Brescia 1-0. Fourth-placed Juventus moved level with Inter after a 1-1 draw with Roma Saturday when Fiorentina beat Cesena 1-0. Sevilla prevails Alvaro Negredo came off the bench to score a last-gasp winner as Sevilla survived the dismissal of Fernando Navarro to snatch a 2-1 victory at struggling Real Zaragoza in La Liga Sunday. Negredo's Brazilian strike partner Luis Fabiano fired the Andalusians ahead in the 29th minute at the Romareda before Nico Bertolo nodded the home side level just after halftime. Sevilla climbed to fourth with 20 points from 11 matches, eight behind leader Barcelona, who won 3-1 at home to third-placed Villarreal Saturday. In other matches Sunday, Manuel Pellegrini scored a win on his league debut as coach of Malaga when it beat visiting Levante 1-0, Hercules saw off fellow promoted side Real Sociedad 2-1, Espanyol were held 0-0 at Racing Santander and Real Mallorca and Deportivo drew 0-0 in Palma. On Saturday, nine-man Athletic Bilbao bettered Almeria 1-0 and Diego Forlan scored twice in Atletico Madrid's 3-0 win over Osasuna. Barcelona's 28 points lifted it two ahead of Real Madrid. Villarrealremained third with 23 points.
