Looking at a post further up suggesting how much DJ , BD and BP could be worth with longer contracts attached , would it be better selling for a nominal fee this window but with a good sell on clause and maybe recoup some money when/if the get sold on for good money ?
But why would they sign contracts if as free agents they can take the transfer fee as a signing on fee? They could possibly pocket millions instead of the club getting the money, and then get a good deal on wages.
Mind you that depends on clubs having cash to do this, which is very questionable with most Championship clubs.
