Jose Callejon and Dries Mertens scored as Napoli snapped Juventus' 22-match unbeaten streak in the Italian Serie A with a 2-0 win.
Defending champions Juventus went into the match Sunday with straight wins in the league but appeared toothless without the suspended Carlos Tevez, reports Xinhua.
Callejon gave the hosts the lead in the 37th minute before substitute Dries Mertens wrapped up the win with nine minutes to go.
Juventus are still 11 points clear of Roma, who won 2-0 earlier in the day against Sassuolo.
