Dalot is currently spending the season on loan at AC Milan, where he has made 10 starts and four substitute appearances in all competitions.
While the 21-year-old has made a positive impression at San Siro, there is no deal in place for the move to be made permanent at the end of the campaign.
According to Calciomercato, Barcelona are willing to pay £10m to sign the Portuguese ahead of the Italian giants.
The report claims that the Catalan giants are eager to increase competition for places at right-back in order to ease the burden on Sergino Dest.
Despite already selling Timothy Fosu-Mensah to Bayer Leverkusen, United are expected to be open to selling Dalot in 2021. body check tags ::
