( CNN ) -- Gonzalo Higuain scored his first Serie A goals since October as third-placed Napoli earned a morale-boosting 4-2 win at Lazio on Monday . Higuain has struggled to match his feats at Real Madrid since joining from the Spanish club in a reported $ 55 million deal in July , but he netted in each half to put the Naples side within three points of second-placed Roma and six of leader Juventus . The Argentina striker put Napoli ahead in the 24th minute at Rome 's Stadio Olimpico but an own-goal from teammate Valon Behrami less than 60 seconds later leveled the score . Fellow forward Goran Pandev made it 2-1 five minutes after the break , and Higuain -- who also had a first-half effort disallowed for offside -- extended the lead in the 72nd minute with his seventh goal in Italy 's top flight this season . Striker Keita Balde Diao pulled one back on 88 , but Higuain 's fellow former Real star Jose Maria Callejon sealed the win with his seventh goal in the league .
