Wouldn't it be interesting for young players, or even old ones like me, to create a "Transfermarkt" tab to find out the market value of players? You present a player and you get all the prices according to various data or criteria.

The problem is that, given that you can now acquire any player from a friend or from the account of your 15th unrecognised child for a symbolic 1 euro, it seems complicated to me to set up this kind of tool, which will inevitably be based on a minimally distorted database.
