thats what clubs do with their "prized possessions" to try and discourage bigger teams from snatching their best players... if you offer a non negotiable deal for half of that they will 90% of the time have to accept!
Mario Fernandes - Gremio is only valued at 2.4million yet last night (I started with Le Mans, got them promoted then I quit as I was losing week in week out and applied to Lokomotiv Moscow) I had to negotiate my *** off to get him for 11million! Rever, Dede etc were all under 3 million yet I could only get them for 9million each (never chose them, I chose Mario)
but that is what happens in the Brazillian league, their base values for their players are about 200% (for the main players) less than what they would be starting out at a big European club so that is why they ask for so much so they can recoup as much of that loss as possible...
