We paid nearly 15 million for them....
And I'd say that's probably what we'd get back, give or take.
We wouldn't make a profit on Kitching or Wolfenden.
The market for CBs isn't particularly high and neither are really that young or good enough to play in the PL. Wolfenden has been a pretty bad buy in the grand scheme of things and not really shown anything to suggest he's more than a middle of the road Championship CB based on his performances this season. Kitching will have a higher stock, but again I struggle to see how we get back for what we paid for him, or if we manage to we certainly wouldn't be able to exceed that fee.
Simms and Torp we'd likely make a decent return on but again neither are good enough to play in the PL so there's a cap on what clubs would pay and similar to Wolfenden and Kitching they're not that young so their resale value isn't great for buying clubs.
So yeah as often is the case I doubt fees received would be as much as people think.
