I saw this the other day, it's nonsense! They've put far too much value on certain players, such as Robertson at a preposterous €94m, Mason Mount at over €100m, and Rashford at over €150m! A good example is they value Timo Werner at €90m and he's literally just signed for Chelsea for €50m.
In saying that, the order is fairly accurate, though with most defenders too high (you pay a premium for attackers) and a few weird decisions e.g. Neymar is far too low.
