Manchester United transfer target wants to return to one of the best midfielders in the world.
The Chilean international has had a difficult year, struggling with several niggling injuries which have made the start of this season particularly a stop-start campaign.
He was linked strongly with a summer move to Manchester United, but manager Louis van Gaal reportedly held off on a move due to his concerns over the midfielder's knee, which prevented him reaching peak performance at the World Cup, and playing a part on Juventus' pre-season tour.
Vidal scored in a Thursday night 3-1 away win over Cagliari, and was buoyant after the game about the team and his own prospects.
He told SkyItalia: "Now we think of Napoli, there are four to five days to prepare the game well and finish the year at best.
"In 2015 I want to go to be among the strongest, and I'm working hard...It's 'important to finish 2014 in first place."
Vidal's aim to be back considered among the best in his position is his own acknowledgement he has had an up and down year by his standards, and is hoping for a fresh start.
Juventus have a winnable Champions League last 16 tie against an out-of-form Dortmund, and strong performances in Europe's top competition can put him back on the map as one of the world's very best midfielders.
The knock-on effect could be renewed interest from Manchester United next summer, but until then that will have to wait.
