Juventus goalkeeper Gianluigi Buffon believes his team can still win the Scudetto despite being seven points adrift of Serie A leaders Inter Milan.
The Bianconeri lost ground on Inter and were leapfrogged by AC Milan after last weekend's 3-2 defeat against Cagliari - their second consecutive loss.
Claudio Ranieri's men travel to Catania this week trailing Milan by a point.
"To be second or third doesn't worry me that much," said Buffon. "It is a temporary overtake by AC Milan.
"The only position that matters is the top spot and we need to reduce our deficit with Inter, starting this weekend. All of the top teams have struggled this year and we have been no exception.
"There are still many games to play and our chances of winning the title remain the same."
• Juventus coach Claudio Ranieri was delighted to progress to the Coppa Italia semi-finals, although he admitted it was not the prettiest of performances against Napoli.
"It wasn't a great display," said Ranieri. "But it was important to get through. We hold the Coppa Italia dear and we showed that.
"In extra time there was more space and we went really close to scoring. In the end, I think this victory is deserved."
The game ended goalless after 120 minutes, but Juve held their nerve to progress 4-3 on spot-kicks.
Walter Gargano missed the crucial one for Napoli to decide a quarter-final which featured 10 yellow cards.
Ranieri's men will now face Lazio in a two-legged semi on March 4 and 22 with the winner playing either Inter or Sampdoria in the final.
