We will lose no money as there is never any guarantee with a sell on clause.
As has been said above, if he sees out his contract we will get nothing at all.
If he moves for the reported fee of circa one million pounds, we will get a sum which the club will not have budgeted for which may enable us to recruit one, or possibly two, decent players, in January to strengthen our promotion push, which will hopefully still be on track by then.
Whichever way you look at it, while the figure might be disappointing compared to what we might have got had he been sold a year and a half ago, it is a bonus for the club right now to get anything at all.
