( CNN ) -- Napoli joined Juventus at the top of Italy 's Serie A after an Edinson Cavani hat-trick blew away Lazio in a 3-0 victory at the Stadio San Paolo . The hosts ' fourth win in five league games takes them to 13 points , with only a missed penalty from Cavani denying Walter Mazzarri 's side from taking top spot outright in the Italian championship . The Uruguayan became the league 's top scorer with five goals after racing to his hat-trick in just over an hour but he blazed a 75th minute spot-kick over the bar . Napoli , who remain unbeaten , now share an identical record of eleven goals scored and two conceded with reigning champions Juventus , who drew 0-0 at Fiorentina on Tuesday . Lazio -- whose German striker Miroslav Klose earned praise after admitting to match officials that he had used his hand when bundling the ball home early on -- suffered their second loss in as many games after starting their campaign with three straight wins . Meanwhile , AC Milan relieved some of the pressure on embattled coach Massimiliano Allegri when beating ten-man Cagliari 2-0 at the San Siro to move tenth in the table . Allegri watched from the sidelines as he served a touchline ban issued after he made heated protests to officials during Sunday 's defeat at Udinese but he would have been delighted to see striker Stephan El Shaarawy grab a double -- and was further boosted by the return of Brazil 's Robinho after a month-long injury . Both Allegri and Milan went into the game knowing that a win was imperative after defeats in their opening games at the San Siro stadium -- against Sampdoria and Atalanta -- had led to the club 's worst home start to a season in over 80 years . The win also meant that one of Milan and Inter , who share the San Siro , had finally won a game -- at the tenth time of asking -- after the installation of a new partially-synthetic pitch over the summer . Having suffered a shock home defeat against Siena on Sunday , Inter responded by moving up to fourth after winning 2-0 at Chievo , thanks to goals from Alvaro Pereira and Antonio Cassano . In the Italian capital , Sampdoria protected their unbeaten record as they recovered from going behind to a first half Francesco Totti goal to draw 1-1 at Roma and take third spot , three points behind the leaders . Elsewhere , Catania beat Atalanta 2-1 , Geno drew 1-1 with Parma , Torino and Udinese played out a goalless draw while Pescara beat ten-man Palermo 1-0 thanks to a late strike from Wladimir Weiss . There was just one game in Spain where Atletico Madrid went second in La Liga , and six points clear of city rivals Real , after winning 4-2 at Real Betis . Colombian striker Radamel Falcao scored twice to overtake Lionel Messi at the top of La Liga 's scoring charts , with Atletico 's thirteen points now just two fewer than Barcelona . In Germany , Szabolcs Huszti and Didier Ya Konan kept Hanover among the league leaders , scoring or assisting in all four goals as the team beat Nuremberg 4-1 at home . Bayern Munich top the Bundesliga after winning their opening five games , but Hanover moved third as Konan 's brace and one from the Hungarian Huszti took their points tally to ten for the season . Hamburg moved out of the bottom three after drawing 2-2 at Borussia Monchengladbach , with former Tottenham Hotspur midfielder Rafael van der Vaart opening the scoring for the visitors .
