Transfermarkt uses the best data available to the public to figure out a rough transfer value for a player.
It takes into account how much of their contract remains, how old they are, how good they are, who they are playing for, how many international caps they have (and for whom) and many other factors to give a rough calculation of their value.
Chelsea spent huge money this summer, and names like Moises Caicedo and Christopher Nkunku top this list, with a market value of €90m and €80m respectively.
What’s interesting is our top home grown players – Reece James is given a value of €55m, which is dropping almost weekly as his injury hell continues, while Levi Colwill is now up to €42m, as he plays every week.
How long will it be before Colwill overtakes his fellow academy product? It could happen as soon as this year, if things carry on as they are.
