ROME — Napoli stayed within striking distance of Serie A leader Roma with a comfortable 4-0 win over promoted Livorno Sunday. Besides keeping Napoli two points behind Roma, which it faces next, the victory also helped the southern squad move on from a 2-0 midweek defeat to Arsenal in the Champions League. Goran Pandev put Napoli ahead three minutes in at the San Paolo stadium, Gokhan Inler doubled the lead in the 26th, Jose Callejon added another in the 54th and Marek Hamsik scored his fifth of the season in the 83rd. Pandev finished off a counterattack after getting set up by Belgium midfielder Dries Mertens and Inler found the target with a long and powerful shot that Livorno goalkeeper Francesco Bardi should have stopped. Callejon scored from within the area after getting set up by Pandev and Hamsik finished off another swift counterattack that followed a Livorno corner by knocking in a rebound. Napoli entered the weekend tied for second with Juventus, which was hosting AC Milan later in a serious test of its title hopes. On Saturday, Francesco Totti scored twice as Roma won 3-0 at Inter Milan to extend its winning start in Serie A to seven matches. The Giallorossi have scored 20 goals and conceded just one. In Sunday's other matches, it was: Bologna 1, Hellas Verona 4; Catania 1, Genoa 1; Parma 3, Sassuolo 1; Sampdoria 2, Torino 2; and Udinese 2, Cagliari 0. Lasogga hits hat trick In Berlin, striker Pierre Michel Lasogga scored a hat trick in eight minutes to lead Hamburg SV to a 5-0 demolition of Nuremberg and hand new coach Bert van Marwijk his first victory in his second game in charge. Hamburg, the only club to have played in the Bundesliga every season since its creation in 1963, secured its first win in four games to move out of the bottom places. The win lifted Hamburg off the relegation playoff spot and into 14th on eight points. Nuremberg are in 16th on five points. Treble winner Bayern Munich reclaimed top spot on 20 points Saturday despite a 1-1 draw at Bayern Leverkusen with Borussia Dortmund suffering its first defeat of the season with a 2-0 loss at Borussia Moenchengladbach to drop to second place on 19. Freiburg is last after a 1-1 draw with visiting Eintracht Frankfurt in Sunday's late game. — Agencies
