Sheffield United could bank around £3million if Che Adams leaves Birmingham City and signs for Southampton.
But 20 per cent of that (£2.8) is owed to Adams' previous club, Sheffield United, as The Star reported earlier this year.
And that could deliver a significant boost to Chris Wilder's summer transfer budget, which is rumoured to be set at around £20m.
Should he indeed join Southampton this summer, his arrival could spell doubly good news for the Blades - pushing two recent Bramall Lane targets, Sam Gallagher and Shane Long, down the Saints' pecking order.
Adams has scored or made 51 goals in 123 games since he was sold by Sheffield United to Birmingham for just £2m three years ago.
The 22-year-old was brought to the Steel City by Wilder's predecessor-but-one, Nigel Clough, whose then side paid Ilkeston Town a nominal, undisclosed fee.
What should Sheffield United do with any windfall received from Southampton's proposed move for the Birmingham striker?
