Juventus coach Antonio Conte admits today's clash with Napoli is a massive test.

The Bianconeri have already beaten Milan and Inter to go top of the table, so their confidence is sky high going into the San Paolo.

"I saw Napoli's game against Bayern Munich on Wednesday and, aside from the start, they showed great strength. It's not easy to fight back from 3-0 down," said the Coach.

"It was no coincidence that right from the start of the season I said Napoli were one of the candidates for the Scudetto. I see the great work that has been done there, first by Edy Reja and then Walter Mazzarri."

Both these clubs have gone through hard times and experienced Serie B, whether down to Calciopoli or bankruptcy.

"Napoli have a two-year advantage over us, as in that time they formed and maintained the spine of the team," continued Conte.

"Let us not forget they were in Serie B like Juve five years ago. They found the right people and a project to work on, so now they are fighting for the Scudetto and are protagonists in Europe despite the toughest group draw.

"I'm confident the Champions League game won't have bad after-effects for Napoli, as everyone in the city is waiting for this match."
