Sheffield United will receive a fee if West Ham United sign Birmingham City’s Che Adams.
They are not the only ones interested, with Sky Sports reporting Southampton have also made an approach.
Birmingham say Adams is not for sale, but a move to the Premier League is likely to be tempting for the 22-year-old.
The forward joined the Blues from Bramall Lane in the summer of 2016 for around £2m. The Sheffield Star reports that United inserted a sell-on clause into that deal.
It means that if Adams does leave during the January transfer window, the Blades are due a cash windfall.
How much will United get?
The exact details of the clause are currently unknown. However, a quick look into the recent past could indicate what it’s likely to be.
The summer of 2017 was a lucrative one for the Blades because of sell-on fees. Both Kyle Walker and Harry Maguire had big money moves.
Walker and Maguire are academy graduates at Bramall Lane, leaving in 2009 and 2014 respectively. The BBC reports that United inserted 10 percent sell-on fee clauses into the transfers.
So when Walker joined Manchester City for £45m and Maguire was signed by Leicester City for £17m, the Blades received £6.2m.
This would therefore suggest that a similar clause would have been included in the Adams deal. If that is the case, a £10m move to West Ham would see United get £1m.
Not bad considering they only sold Adams to Birmingham for double that.
It also emphasises how incredible the South Yorkshire club is for nurturing young talent. Another academy graduate in Dominic Calvert-Lewin is also in the top flight with Everton.
Adams may not have been a youth product at Bramall Lane, but did arrive from non-league as an 18-year-old.
