Manchester United remain determined to sign Jadon Sancho from Borussia Dortmund this summer, but an inability to agree personal terms with the player and negotiate an agent fee with his representative is holding up any deal with the German club, sources have told ESPN.

United have been given the green light by Dortmund to speak to the Englandwinger and his representative, although direct contact between the two clubs has been limited as a result of the impasse with the player's camp.

Sources have told ESPN that United are confident of striking a deal with Dortmund once, when, or if, it gets to the stage of negotiating a transfer fee with the Bundesliga side.

But sources have also said that there remains a wide gulf between the expectations of the Sancho camp and United's view of the 20-year-old's salary demands. The fee required by the player's agent to negotiate the deal is also too high for United to contemplate agreeing to.
