United allegedly expressed an interest in Rabiot in 2019, only for the Frenchman to leave Paris Saint-Germain for Juve on a free transfer.
Although the 25-year-old has made regular appearances for the Old Lady, the Italian giants could cash in on the player during the summer window.
According to Tuttosport, United are ready to make another approach for Rabiot, this time including Donny van de Beek as a makeweight in the deal.
The 23-year-old, who cost £40m last year, has been provided with just five starts and 16 substitute appearances in the Premier League and Champions League this season.
Juve are admirers of the playmaker, something which may help United if they instigate talks over the coming months.
