Tevez has not been called up for the Argentines since Sabella took charge of the team in 2011.
While it has been suggested that the Juventus striker could earn a dramatic recall ahead of the tournament in Brazil, Sabella has played down a possible return for the 30-year-old.
"I don't like talking about the players who aren't in the squad. I think it's better for everyone that way," he told FIFA's official website.
"That goes for Tevez and for anyone else, though I understand why they're talking about him more than others."
Tevez has scored 18 goals in 40 games for Juventus this season.
