The on loan ace wants to give his all for the club between now and the end of the season to help the team cement their challenge for a UEFA Champions League place.
"At this time I only want to give Parma a good end to this season," he told the club's official website. "Personally, there is nothing special about Sunday's match.
"However, I'm not hiding the fact that facing a team like Juve, gives big stimuli and great motivation."
The midfielder has only recently returned to action, after receiving a ban for testing positive for nandrolone back in October.
"I've been out for a long time. It's my duty giving my best for this team and especially for the supporters," he added.
"I think this is really time to face Juve. We are in a good form. Juve are really dangerous, but considering our form, we are confident."
