This is just a theory, but it may be actually easier than ever to sell your players now?
For example - there is only ONE 5* player on the TM now yes?
Therefore, when you come to sell your 3* player, it may appear 2 levels below you as the only 5* player on their list.
This may cause bidding wars as everybody wants the only high quality player on their list, which means you get more bang for your buck.
Seems rubbish for buying players though.
