You're using the benefit of hindsight with Wharton, do you genuinely recall people claiming he was undersold at the time?
After Spurs take their cut for Clarke? So you'd need the buying club to be offering a fair bit more than the £17m.
So to use Ekwah and the underselling proposal, would you accept the 5m euros we've apparently been offered for him? Would you have accepted the supposed £7m for Hume? Would you have accepted the £15m for Clarke? Where is it you draw the line?
Just to reiterate, I'm wholly on the same page as you in terms of acknowledging we need a big sale to evolve and progress as a club but I just believe you can't make other clubs buy your players and I personally wouldn't advocate underselling anyone.
