The full-back acknowledges Juve have difficult games ahead - including Saturday's home game with Genoa - but that a trophy is well within their grasp if they continue on with their good start to the campaign.
"We have difficult games coming up [Genoa, Fiorentina, Inter and Napoli] and so we cannot really speak about the Scudetto now," Lichtsteiner told Sky Sport Italia.
"But if we can continue along this path then I am sure we will achieve great things."
The league leaders were held to a goalless draw at Chievo in Verona last weekend and Lichtsteiner has warned his teammates not to take Alberto Malesani's men lightly on Saturday.
"We will have to be careful against Genoa as they have good strikers, but we are preparing well and I have faith," he said.
If Juventus slip up against Genoa on Sunday, Udinese can take over sole possession of first place with a victory over Novara at the Friuli stadium.
Six games into the season and Udinese and Juve are level on 12 points and the only teams unbeaten in Serie A.
