On-loan Bournemouth midfielder Philip Billing scored a late goal to rescue a crucial point for Napoli against Serie A title rivals Inter Milan.

Federico Dimarco opened the scoring with a stunning free-kick, curling the ball over the Napoli wall and into the top left corner - leaving goalkeeper Alex Meret rooted to the spot.

Napoli dominated from there with Romelu Lukaku, playing against his former side, and Scotland's Scott McTominay both going close to scoring an equaliser.

But it was substitute Billing, who joined on loan from Bournemouth in January, who levelled when he latched on to Stanislav Lobotka's pass and tapped home the rebound after seeing his first effort saved by Josep Martinez.

The result means defending champions Inter maintain their one-point lead over Napoli, who missed the chance to move top last weekend after a surprise defeat by 13th-placed Como.

Third-placed Atalanta were unable to increase the pressure on the top two, as they were held to a goalless draw by Venezia that leaves them three points back.

Inter boss Simone Inzaghi might have to contend with further injury concerns, however, as both Dimarco and Hakan Calhanoglu limped off in the 50th minute.

Inter are already without first-choice goalkeeper Yann Sommer and full-back Matteo Darmian as they turn their attention to Wednesday's trip to Feyenoord for the first leg of their Champions League last-16 tie.
