Ranieri, who helped Parma avoid relegation after taking over in mid-season, took the reins of Serie B champions Juve.

"I give the right importance to the all (warm-up) tournaments, but at this moment the fundamental thing is the preparation," Ranieri said.

Juventus, who just completed a tour of England and Germany with matches against Newcastle, Sunderland and Hamburg, will now play in a series of games in Italy.

On August 8, Juventus travel to Naples for the Birra Moretti Trophy with newly-promoted Napoli and Internazionale also taking part.

Juventus then take on Roma in a friendly on Saturday in Cesena before moving on to Milan for the TIM Trophy to take on both Inter and AC Milan, beginning on Tuesday.

On August 17, Juventus will be in Milan for the Luigi Berlusconi Trophy against AC Milan.

"We welcome these tournaments because we are playing against top teams and it's a way to prepare, to breathe the climate of championship," Ranieri said.
