> That doesn't make any sense whatsoever to an avid, European, football fan like me at least
Can you explain how ownership of a player's rights works in European football? As a non-football fan from North America, I have always found it confusing when I hear about the huge fees it costs move a player, before his salary is even discussed, as I'm more familiar with the simpler trade/free-agency model used by American sports leagues.
What about player loans, how are those even a thing?
I've tried googling/wikipedia-ing it more than once, but these concepts are often not dumbed down enough for me.
