The World Cup winner was a free agent after his contract with Manchester United expired lat month.
After completing his medical, the 29-year-old will sign on the dotted line with his former club.
Pogba left Juve for United back in 2016.
The Frenchman declared he had been offered 'nothing' by United at the end of his contract.
That is despite the Premier League putting forward a contract offer of £290,000 a week.
