Napoli, who qualified for the Champions League knock-out stage in midweek, needed an 84th-minute equaliser from Blerim Dzemaili to earn a 1-1 draw at relegation-threatened Novara.

Cagliari and Parma shared the spoils in a dour 0-0 stalemate at the Stadio Sant' Elia.

Cagliari, who have won just once at home this season, mustered very little and were fortunate to clinch a point that saw them climb to eighth place and remain one point clear of Parma.
