The 20-year-old, who departed Manchester United for Juve in 2012, has developed into one of the best midfielders in world football.
That has led to reports of outside interest, but the French international has refused to be drawn on rumours linking him with the Bernabeu.
"I don't think about all that," Pogba told L'Equipe. "I am only thinking about the pitch and achieving good things. I don't know anything about what happens behind the scenes."
Pogba's current deal runs until 2016.
