United have agreed terms with Pogba and are hoping the French midfielder signs before the end of the season.
Pogba has also been offered a lucrative deal by Juventus, but Fergie said: “We’ve agreed a deal with his agent and now it’s just down to the boy.
“He knows what the qualities are, what United have got to offer.
“He knows his future is guaranteed here. He is going to be a first-team player here, without question.”
