Manchester United are expected to formally submit an improved bid to Barcelona for Frenkie de Jong imminently.
United made an opening offer of €60million (£51.64m) including add-ons that was rejected by Barca, who are unwilling to suffer a loss on a player they signed for £65m three years ago.
Barcelona privately concede they cannot obtain the outlandish €100m Spanish outlets have quoted as their valuation of De Jong, 25, when they are prepared to sell him. Barca are believed to want a guaranteed €75m (£64.55m), with add-ons to ensure De Jong's overall fee surpasses what they paid Ajax to sign him.
