Hi there,
Transfers are for a large part random, which is not appreciated by everyone. Gamebasics knows things needs to be changed, but it will require a huge undertaking and is therefore considered as a long term project.
Also, on 16 and 17 April we had the Transfer Madness event, which means that selling chance had increased. That way it is a bit easier to sell expensive players. I take it that these screenshots are from those two days.
