Juventus have had a tough pre-season where they won only two out of seven games, much to the worry of their fans.
Chiellini admitted that the Bianconeri will have to work extra hard before the start of the season and to not take their position as defending champions as granted.
"Conte is correct - talent needs to be nurtured on a daily basis with hard work," the 28-year-old told Tuttosport.
"We know that you can only achieve certain targets by working. And we want to affirm our place in Italy and improve in Europe.
"Last season we beat the holders in Chelsea, dominating our home game with great authority in the Champions League. Obviously, though, when you play the likes of Barcelona, Bayern Munich and Real Madrid, you have to take them on at your physical best."
Chiellini has reassured fans that Juve's pre-season results will have little bearing on the team's actual performance when they face Lazio in the Supercoppa Italia on Sunday.
"It's normal to have tiredness and a lack of spark at this point of the season, but we are growing and we'll certainly be ready for an important meeting on August 18," he continued.
"We want to win the Supercoppa as much as Lazio. We want to start the season on the right foot and, on Sunday, the pitch is where we will ultimately be doing the talking."
