The Red Devils have endured a quiet transfer window after only signing Netherlands international Donny van de Beek from Ajax Amsterdam earlier this month.
Now according to RMC Sport, the Premier League side have agreed a five-year deal with the Brazilian full-back.

The report adds that Telles is also being chased by Ligue 1 Paris Saint-Germain, who have also been quiet in the transfer window.
United have also been linked with Real Madrid left-back Sergio Reguilon recently, but he is expected to join Tottenham Hotspur in the coming days.
