I would Love to see the availability of Loan Players upto Max of 2 loan players in squad for season and if you send 1 back allowed to loan in 2nd player again.
Be in full control when selling a player and having the option to agree to final offer on player then If sale agreed gain some of the tokens used by the Bidders .
With the Academy's would be nice to run a Reserves team and work on the positions of Academy players coming to your squad.
Lastly I doubt can be done but would be great to be able to text with fellow managers
