The 35-year-old entrepreneur backed 'the Bull' to shine at the Stadio Olimpico, whilst hitting out at racism which has become synonymous with Serie A
The 35-year-old entrepreneur is just one of a number of Bianconeri followers to have been impressed not only by the Argentine's goals, but also his aggression.
However, Elkann remains wary of the threat posed by Torino, and their in-form forward Alessio Cerci in particular.
"Who will decide the derby? The bull, Tevez," the brother of FIAT chairman John Elkann told Tuttosport.
"In the Champions League, Juve has not started at their best. But, as in life, it is wrong to make a judgement right at the start.
"Over the past two years, the club has shown strength and determination in every sector. They can go far this season.
"But beware of Cerci. Beyond the individual talent, I have to say that the coach [Giampero Ventura] has done a good job overall."
Meanwhile, Elkann then turned his attention to the incidents of racism that have marred the opening rounds of the new Serie A season.
"Enough with racism," he pleaded. "Italian football has become an adult: one has to be civil. Enough wasting time and energy with this negativity.
"For the sake of Serie A, there needs to be positivity, as we are losing competitiveness not only to the Liga, but also to the Bundesliga, Premier League and even Ligue 1."
The Derby della Mole is scheduled to kick off at 12:30CET on Sunday.
