Manchester United will hold further talks with Adrien Rabiot's mum Veronique on Monday.
Football director John Murtough met Veronique in Turin on Friday and scheduled to reconvene talks over her son's personal terms at the start of the week.
A fee is already in place between United and Juventus for the France international midfielder.
United also want to add a striker and winger and have a number of options under consideration. PSV Eindhoven's Cody Gakpo and Stuttgart's Sasa Kalajdzic remain on the list.
United will have more funds to play with if their move for Frenkie de Jong collapses amid concerns he will join Chelsea instead.
