The powerful defender has hailed the experienced attacker, and was very pleased with the Old Lady's defensive display in what he feels was a "fundamental" win
The veteran attacker scored his side's second goal of the evening to effectively put the match to bed after Martin Caceres had given the Bianconeri the lead, and Chiellini feels that Del Piero made the difference for the Turin giants when he came on as a 53rd-minute substitute.
"He [Del Piero] deserves this recognition, along with our other team-mates who don't feature in every single game," Chiellini stated to the official Juventus website.
"Whenever they come off the bench, they manage to make the difference for us. These players give us something extra that can help us to a successful season."
The Italy international then went on to underline the importance of Sunday's victory, and expressed his delight with Juve's defensive display.
"It was important to win in a fundamental game. We barely concede goals because we all do a great job defensively.
"When we all press high, we run a lot and hold our positions, which makes everything easier."
Juventus remain second in the Serie A table, trailing leaders AC Milan by four points. They host Napoli in their next league encounter.
