Napoli coach Carlo Ancelotti was floored after their 4-3 defeat to Juventus.

Napoli fought back from 3-0 down in the space of 16 minutes, but were beaten in stoppages by a bizarre Kalidou Koulibaly own goal.

“It was not a positive test, as we played badly for an hour. It seemed over, we got it back on track and it could've ended 3-3 or 4-3, it wouldn't have changed the fact our performance was insufficient," Ancelotti told Sky Sport Italia.

“The game changed because Juve focused on the counter-attack after going 3-0 up and we took more control of the ball. Lozano added more weight to the attack, but it wasn't just his introduction.

“We allowed Juve to press us, Fabian Ruiz was left isolated throughout the first half and we never found him, because the spaces to go on the counter were there, we just didn't use them.

“The defence was in place with seven or eight players in the final third on the Gonzalo Higuain and Cristiano Ronaldo goals, so it's not as if we were caught on the counter then.

“We were unable to find Fabian Ruiz, but we did better after the break when we moved things around and he was able to hurt them.

“The defence is not an individual issue or one of technique. We conceded seven goals in two rounds because the whole team aren't sacrificing themselves enough to help out."
