Manchester United have agreed a £63.5m deal with Barcelona for Frenkie de Jong but there is still no guarantee the move will go ahead.
They now know what they have to pay for manager Erik ten Hag's key target, with the agreed deal equating to a bigger up-front payment and £8.5m in add-ons.
However, the player's dispute with Barcelona is threatening the move.
The contractual disagreement centres on deferred payments that were included in the playmaker's new four-year deal that only became active on 1 July.
There have been widespread reports in Spain that Barcelona have told De Jong he needs to leave for financial reasons.
