The ex-Bianconeri official is full of praise for the forward's industry and selflessness but he does not feel that the 29-year-old is a natural goalscorer
The Bianconeri signed the forward from Manchester City this summer and the No.10 has enjoyed a positive start to his career in Turin, having already racked up two goals in three Serie A appearances.
However, Tevez failed to net in the midweek Champions League draw with Copenhagen, a game that Moggi feels proved that the ex-West Ham man is not the natural goalscorer that Juve have been craving for so many years.
"This is a moment in which they are not running as they should," the Monticiano native wrote in Libero. "They do not sting, do not hurt the opponent.
"But if the attack does not score or makes mistakes, the blame should not be put on Tevez, who is a support striker.
"He wears himself out for his team-mates in attack, looking for space for himself and others.
"And if he does not shoot on goal or makes a mistake in front of the opposition goalkeeper, it is down to the fact that he does not have those particular characteristics of a striker.
"He is a good player, but is certainly not one of those champions who can win games on his own."
Tevez, who has not been capped by Argentina since 2011, joined Juventus for an initial fee of €9 million.
