It is incorrect to say nobody owns a players when they are placed on the market, the money goes to the guy that put him up, which is the issue here.
fif he goes to the normal value of the player he risk to get him himself, which will cost him the same money like buying a new player. So if he is the best priced player on the market, it is a good decision to buy him himself, but thats count also for all cheap players.
To bid on him to raise just the market value, will maybe give sometimes you extra money, but sometimes you will loose it also because you buy him himself orscare other bidders and reduce your income - for me i wouldn't recommend this strategy to anyone.
As I have said all along, my issue isnt about managers wanting to buy back their own players if they choose too,my issue is with the system that you have to use to do it as it allows price hicking.
because in the current system you could prevent him for doing it, and bidding over market value is as bad for the guy who buys him back like for the guy who buys him "new". because both players got the money to make a better deal. And bidding more then he is worth, also would end in getting himself in most cases ;)
Thats why i don't like it when everybody just could erase their players from the transferlist, because it makes the trnasfer market even more unpredictable, when your drem player get often removed from the list(and how you want to punish people who take back transfers?)
