Manchester United are facing further delays over signing Barcelona midfielder Frenkie de Jong.
The Holland international has seen Barca accept an offer of €65m up front plus a further €20m in bonuses.
However, holding up the deal is a pay-out De Jong feels he is owed.
The midfielder agreed a hefty wage deferrment for the past two seasons to help Barca through their financial problems, says Marca.
And De Jong feels he deserves the money owed by Barca before agreeing to leave for Old Trafford.
The midfielder has a deal with Barca to 2026.
