Pogba'ss agent Mino Raiola said the player wants to leave, with Real Madrid and former club Juve keen.
“I am not the technical director, so I do not know [if Pogba will come to Juventus]," Sarri said.
The comments come after Raiola this week suggested Pogba's future may lie at Old Trafford after all.
"The future of people is not written," Raiola said. "We will see. Will he stay in Manchester? I live my life day by day."
