Inter led twice, and Napoli did enough not to lose and allow the leader to make the first noticeable difference in the Serie A standings.
There was no winner in the derby (2:2), so Inter still has four points more than the current champion, three more than Milan, who drew away against Fiorentina in this round (1:1).
Roma is also four points behind Inter after defeating Sassuolo.
The "Black and Blue" took an early lead with a goal by Federico Dimarco after Piotr Zielinski took the ball away from Scott McTominay, but the Scot later redeemed himself and only he deserves the credit for the Neapolitans taking a point from the City of Fashion.
Mektomine is equalized midway through the first half at 1:1, a ten minutes before the end and at 2:2 after it is Hakan Çalhanoglu's penalty gives the home team their second advantage.
