Napoli are being held to a goalless draw in their Serie A meeting with Atalanta BC this afternoon.
Giacomo Bonaventura wasted a chance to open the scoring midway through the half, but powered a header over the bar from a promising position.
The visitors were forced into a change, as Mario Yepes had to be taken off following a collision with the keeper.
Dries Mertens came close to giving Napoli the lead on the stroke of half time, but saw his low effort saved by Andrea Consigli.
