#2 – Player-Manager mode
Player-Manager was an exiting thing for many players but EA Sports decided to remove it all of a sudden. Having the control over transfers and also subbing yourself on when needed was a really good thing and that is something EA should bring back in FIFA 20.
#1 – Flexibility in the transfer market
One thing that irritates me, especially while managing a big club, is the fact that I can't ask for a player from the negotiating team in return for my player. But at the same time, when you are the one negotiating for a player, they are able to ask for a player from your squad.
Along with the option to request for a player in return, EA Sports should also introduce 'offer player on loan' and 'ask for a player on loan' in the options. Getting a player on loan would be a huge boost to the small clubs that are aiming for promotion or survival.
