Serie A: Two goals in the first five minutes helped Inter Milanease to the top of Serie A with a 3-1 win over Napolbut city rivals AC Milan were beaten in Udinese.
Inter coach Jose Mourinho was banned from the bench after being sent to the stands in Sunday's 2-1 win at Cagliari, but the champions produced a roaring San Siro start without him.
Samuel Eto'o tapped in the first after Walter Samuel headed on a corner and strike partner Diego Milito soon beat the offside trap to score his fifth in five league games this term.
"To start like this, I could never have imagined it," the close-season signing from Genoa said. "We had a fantastic first half. We've won and played well."
Lucio nodded in another corner after the half hour mark with Ezequiel Lavezzi pulling one back for Roberto Donadoni's side, who have picked up just four points so far despite spending big.
Inter went above this Saturday's opponents Sampdoria, who dropped points for the first time this term when headers from Stevan Jovetic and Alberto Gilardino either side of the break sealed Fiorentina's2-0 home win.

The Italy striker also struck the post while Milan, who started with Ronaldinho on the bench and had Mathieu Flamini dismissed for a second booking late on, hit the bar through Alessandro Nesta's header.
