Fabio Capello has preached patience with Juventus coach Ciro Ferrara, as the rookie boss attempts to build a Scudetto contender.

Bianconeri president Jean-Claude Blanc has given Ferrara his vote of confidence following Cagliari's upset win against Juve, but things could go downhill if they lose in next weeks' Derby d'Italia against Inter Milan.

"Inter are a strong and compact outfit that are domineering in Italy, as proved by the results over the past years," Capello told Tuttosport.

"On the other hand, Juve want to go back to having a starring role in the league. It will be a clash between a team that aim to consolidate its leadership and another that want to test its ambitions.

"Inter have had time to strengthen and make some changes. Juve have strengthened too, but need time to mature. Let's give this Juve a little more time.

"Inter were already strong and made key-hole adjustments, while it's more difficult for Juve to find the right path."
