SSC Napoli inflicted a 5-0 drubbing on Cagliari to increase their lead at the top of Serie A to four points, though second-placed Juventus have a game in hand. For the visitors, it was a club-record 10th straight league victory. Real Madrid veteran Jose Callejon on Monday put Napoli up 1-0 with a goal in the 29th minute and the away side led 2-0 at the break courtesy of a strike in the 42nd minute by Dries Mertens, who connected with a cross from Elseid Hysaj, reports Efe.
