The Italy international believes Juventus has the quality to win a third successive Scudetto but is wary of the stiff competition it faces in 2013-14
The Turin giants finished last season with a nine-point lead over runners-up Napoli to secure its second Scudetto in a row and the defender is hopeful of winning a third this term - although he acknowledges that sides have struggled to achieve the feat in the past.
"History dictates that winning three consecutive championships is very difficult," Chiellini was quoted as saying on the club's official website.
"We’ve got everything required to do it, but it won’t be a walk in the park. After all, it wasn’t a straightforward run to the title last year, given that the gap in the table was minimal in January.
"Then we did well to motor along stronger than the others when people thought we might have paid the price for our involvement in the Champions League."
Chiellini believes that Napoli, AC Milan, Inter and Fiorentina are set to provide Juventus the biggest challenge to its championship crown next season.
"Napoli have made wholesale changes, they’ve got a new manager and will play in a different way," he said. "The likes of Milan, Inter and Fiorentina are slightly ahead of the rest. I view these teams as our most realistic challengers in the Scudetto race."
