Inter Milan gave new coach Leonardo a flying start to his San Siro career with a 3-1 win at home to Napoli on Thursday as neighbours AC Milan moved five points clear at the top with a 1-0 win at Cagliari.
Former Milan boss Leonardo, who replaced Rafael Benitez, saw Thiago Motta grab a brace while Esteban Cambiasso added the other to sink Napoli, who replied through Michele Pazienza.
Inter are still 13 points behind Milan in seventh but they do have two games in hand.
Napoli dropped to third, six points off the leaders and just one behind Lazio who drew 0-0 at Genoa.
Inter enjoyed the best possible start at the San Siro as brilliant one touch football between Goran Pandev and Dejan Stankovic sent Motta through to hit a first time volley beyond Morgan De Sanctis on three minutes.
However Napoli were level on 25 minutes as Pazienza headed home an Ezequiel Lavezzi corner.
Cavani then teed up Christian Maggio who should have done better than drag his shot wide of the far post.
On 35 minutes Diego Milito should have given Inter the lead but somehow spooned over from six yards.
Yet two minutes later they were in front as Cambiasso arrived late and at pace in the box to head home Maicon's cross.
Napoli's Marek Hamsik stabbed wide from an early second half chance before it was three as Motta sent a brilliant header into the top corner on 55 minutes.
Inter captain Javier Zanetti had the best chance thereafter but pulled his effort across goal.
Sierra Leone international Rodney Strasser pounced five minutes from time to score the only goal of the game in Sardinia as AC Milan beat Cagliari 1-0.
Controversial signing Antonio Cassano, on his debut as a substitute, slipped in the 20-year-old to beat Michael Agazzi in the Cagliari goal.
