Roma have won their first nine matches in a row to sit top of Serie A, five points clear of closest challengers Juve and Napoli.
Tevez thinks that Juve must focus on themselves and finding consistency over a long season, after they returned to winning ways in a 2-0 success over Genoa yesterday.
He told reporters: "It's no problem, there's a long way to go. The important thing is that we carry on playing like this.
"We needed to respond to our defeat in Florence and we managed to do just that. We played in the way that boss Antonio Conte had asked us to.
"Am I a leader and example? I'm always keen to help out my teammates, especially since people were saying that we were in crisis."
The Argentine netted his fifth goal of the campaign against Genoa, quickly becoming something of a talisman for the Bianconeri.
