Manchester United have agreed personal terms with Everton defender Jarrad Branthwaite, with the Merseysiders valuing the 21-year-old at at least £80m.
United intend to speak to Everton about Branthwaite after the transfer window opened on Friday.
The response is likely to be frosty.
BBC Sport has been told Everton do not want to sell Branthwaite, whom many believe was unlucky to miss out on selection for England's European Championship squad.
The club believe it is just a matter of time before Branthwaite becomes an England regular and rate him in the same bracket as Harry Maguire and Josko Gvardiol.
