The intriguing Championship five-year player sale profit rankings - including Derby County, Stoke City and more

One area of real interest in modern football is how well clubs invest in talent to sell on, with the wildly inflated market meaning a player could be bought for a bargain fee one season and flogged for big money the next.

At the opposite end of the spectrum, some players command multi-million pound fees, before winding down their contracts and leaving for nothing a few years later.

In the case of some clubs, like Derby County, this can have disastrous consequences to their balance sheets, and play a role in the nightmare scenario of going into administration.

Now the window has closed, we've taken a look (via BettingOdds.com) at how much profit on previously purchased players every Championship club has made over the last five years. Sales of academy players are also factored into the figures.

This is how every Championship club’s percentage on players sold over the past half-decade of transfer activity ranks.
