Napoli fullback Mario Rui admitted frustration after their 0-0 draw with Chievo Verona.

The match marked Rui's Serie A debut.

"It certainly wasn't the match I was hoping for," the left-back, on loan from Roma, said.

“I felt good and I am happy to be back on the pitch.

“I wanted a debut with three points and I will look to give it everything to get back to the top.

“Chievo prepared very well for the match. The team didn't do badly and we moved the ball well.

“We lacked that little bit of ruthlessness in the final third."
