The caretaker boss is expecting a backlash from their forthcoming opponents on Sunday, while also commenting on his side's activity in the transfer market
The Zebrette recently failed to secure a place in the Champions League group stage at the final hurdle, crashing out on penalties to Braga in the last round of qualification.
Carrera, deputising for the suspended Antonio Conte, has gone on to urge his side to expect a backlash when they travel to the Friuli for matchday two of the new Serie A season.
"We will encounter a team with wounded pride," the former Italy defender said at a press conference ahead of the tie.
"These are the most serious of challenges and will not be be easy. Juve will have to give 110 per cent."
The San Giovanni native went on to comment on the Old Lady's activity in the transfer window, which saw them bring in the likes of Sebastian Giovinco, Lucio, Kwadwo Asamoah, Mauricio Isla and Nicklas Bendtner.
"Satisfied with the market? We have a competitive squad," he noted
"We are happy to be back and to have players that have won the Champions League. We will try to do what everyone expects from Juve; move forward as much as possible."
