With leaders Inter Milan only managing a draw at Parma on Saturday, Napoli had a chance to close on them, but they remained second with 65 points, three behind. Bologna are fourth on 57 points.
Napoli struck after 18 minutes when Zambo Anguissa seized a loose ball on the halfway line, burst past a stunned Bologna defence, and calmly rounded goalkeeper Lukasz Skorupski to slot the ball into the net.
The moment of the match came four minutes after the hour mark, however, when Bologna’s Ndoye received a pass inside the box and executed a brilliant back-heel flick that hit the underside of the bar before bouncing over the line.
