Manchester United are reportedly planning to make an improved offer for Crystal Palace right-back Aaron Wan-Bissaka.
The Red Devils are believed to have fallen short with their initial £35m bid for the 21-year-old on Monday, which included a further £15m in add-ons.
Sky Sports News claims that United have not made a second approach in the three days since, but they are planning to do so.
Palace are believed to be after between £45m and £50m upfront for the England Under-21s international, who has just one full season of Premier League football behind him.
England coach Aidy Boothroyd admitted on Thursday that Wan-Bissaka's head has been turned by the interest from United.
