Manchester United are due a tidy windfall from Real Madrid's sale of Cristiano Ronaldo last year to Juventus.
United will get around 850,000 from the Serie A giants as part of the 99m deal which saw the forward, 34, leave the Bernabeu in the summer of 2018.
A Man Utd source is calling the money "the second instalment of a solidarity payment".
Solidarity payments - introduced by Fifa in 2001 - are usually one-off lumps sums considered compensation for signing a player aged 23 or under.
Juventus' financial records for the season were recently revealed - with the payment to Man Utd showing up.
