The Premier League giants are lining up a deal to sign the 23-year-old Barcelona winger if they fail to sign their top target Jadon Sancho in the final stretch of the transfer window.
Dembele wants to stay at Barcelona and is not in favour of a move to the Premier League with Manchester United in the final days of the window.
Manchester United are in talks with his entourage to convince the player and they have even employed Pogba to do their bidding as well.
According to Spanish daily Mundo Deportivo, the Manchester United midfielder is in contact with his compatriot to convince him to move to Old Trafford.
The Frenchman has assured Dembele that he would find a conducive environment at Manchester United under the tutelage of Ole Gunnar Solskjaer.
Pogba has also been trying to convince the player that he is likely to get more opportunities to play at Manchester United this season than at Barcelona.
Manchester United are working on the Dembele track but he is still their plan B if they fail to sign Sancho.
