Marcelo Zalayeta has struck 17 minutes from time to earn Napoli a deserved 1-0 win over Inter Milan, their first under Roberto Donadoni as the Kaka-Inzaghi show hauled Milan within seven points with five games to go.

A wonder goal by Zlatan Ibrahimovic once again strengthens claims that he is the world's greatest striker as Inter Milan took three points and scored three goals against Reggina while Napoli hosted Milan and Juventus thrashed Roma.

AC Milan and Bologna cruised past Atalanta and Sampdoria respectively as World Cup Champion Filippo Inzaghi and ex-Azzurro Marco Di Vaio were the only names on the scoreboard in their side's 3-0 wins.

Inter Milan's lead at the top of Serie A is down to seven points after they were forced to come from two goals down to draw 3-3 with Roma while Catania won the Sicilian Derby after thrashing Palermo 4-0.
