Should a deal go through, there would be a welcome windfall for Man Utd, who included a sell-on clause in their agreement with Forest two years ago. The report puts the clause at 15% of the profit of a future sale, though other Mail sources suggest it's as high as 20%—a figure that would see United pocket a cool £8 million ($10.9 million).

When Manchester United sold the 23-year-old to Forest in 2023 for £15m, they inserted a sell-on clause which will see the Red Devils owed a reported 15 per cent of any profit. That would mean the Red Devils receiving 15 per cent of £40m, which clocks in at £6m.
