The 35-year-old is hopeful the Turin side's new signing can lead the club to Champions League glory this season having signed from Serie A rival Napoli.
Andrea Barzagli believes Gonzalo Higuain could make the difference for Juventus as the club goes in search of its first Champions League title in 20 years.
The Argentina international joined from Napoli in a deal worth 90 million euros ($100M), signing a five-year contract with the reigning Serie A champion.
Juve made it to the final of the Champions League in 2014-15, but crashed out in the round of 16 last term and is desperate to go all the way this time around.
