The Argentine striker has been the breakout star of the Serie A season, netting 13 times in 34 appearances, and has been linked with the likes of Arsenal, Manchester United, Chelsea and Paris Saint-Germain over the course of the 2014-15 campaign.
However, Juventus emerged as the frontrunners and last week Palermo claimed an agreement was in place to take the in-demand 21-year-old to Turin.
Dybala himself has now confirmed that he is bound for the Champions League finalists and is confident that he can justify the Bianconeri's reported outlay of €40 million.
"Juventus are the team that wanted me most," the forward told Sky Sport Italia.
"They made a great effort to sign me and I have chosen them for this reason.
"I've grown a lot in these last few years at Palermo and I think that I can grow even more at Juventus. I can still improve so much.
"I will give my all to show that Juve have done right spending all of this money on me.
"When I arrived at Palermo, they said that they spent too much on me. However, with time I replicated what I had done in Argentine.
"Now, it will be same."
Dybala also revealed that he would like to see Carlos Tevez, who has one year left on his Juve contract, extend his spell with the Italian champions.
"For me, it would be better if he says," the youngster added. "With him by my side, it would be easier to learn."
