"We did what we had to against Roma, as we were the 'home' side and couldn't help but win," said Hernanes. "I think Lazio have been doing well for some time and it's not a single game that changes the view of the fans.
"It's always important to do well and we want to do it with Juve too. Now there is Juventus and we know this is a difficult place to play. If you'd asked me two weeks ago, I would've said it was an impossible mission and Juve were unbeatable.
"However, after Inter's victory something has broken, maybe even subconsciously, and now we all believe that we can win there."
Lazio are currently fifth in the Serie A standings with 22 points from 12 matches.
