Napoli boss Carlo Ancelotti defended their 0-0 draw at Champions League opponents Genk.

The Azzurri hit the woodwork three times and saw Kalidou Koulibaly's effort cleared off the line at the Luminus Arena.

“It was a good performance and we had several chances for the breakthrough," Ancelotti said on Sky Sport Italia.

“Our finishing wasn't very effective and we were a little unlucky too. The only risk we had at the back came after a slip, so we were always in control.

“It's an extra point, we showed grit and determination, but could've finished our chances better."
