As Forest survived relegation at the expense of Blackburn Rovers, Wanderers are now owed a six figure sum.
The article states:
"Nottingham Forest's survival in the Championship has activated another payment clause in Zach Clough's transfer from Bolton.
The Reds will have to pay Wanderers a six-figure sum as part of the £3m deal that took him to the City Ground.
And Forest will be hopeful they have to make another additional payment to the newly-promoted Lancashire club this time next year – as there is also a promotion clause as part of the package, that would be due were Mark Warburton's side to make the step up to the Premier League in the future, while Clough is still part of the squad.
Bolton also inserted a sell-on clause in the deal, which brought the talented 22-year-old to Nottingham in January, when Gary Brazil moved to sign the attacking midfielder or forward."
It's good to here that there's a sell on clause, as Clough has already hit the ground running with Forest, having scored four times, including against rivals Derby County. If he keeps the strong performances going, Wanderers could be seeing more cash coming their way.
