AC Milan's poor form continued as they were held to a 1-1 draw by Genoa, despite taking the lead and playing against 10 men for almost an hour.
Kaka gave Massimiliano Allegri's side the perfect start with a fine finish after just four minutes.
Alberto Gilardino equalised with a ninth-minute penalty but Genoa's Thomas Manfredini was sent off for a foul on Mario Balotelli in the 36th minute.
But Balotelli saw his ensuing penalty saved and Milan were held.
Allegri's team, who are 11th, are without a Serie A victory in five attempts and have won just two of their opening 13 league matches.
Third-placed Napoli were beaten 1-0 at home by Parma, their second consecutive defeat after a 3-0 loss to Juventus two weeks ago.
Antonio Cassano scored the winner for Parma in the 81st minute after an impressive solo run.
Elsewhere, Dejan Lazarevic scored the only goal as struggling Chievo beat derby rivals Verona 1-0.
