You could do what I used to do for FIFA 08 and still do for Madden 08 (since it's not on PC anymore), just find a modding community that will take care of the rosters for you and add smaller graphical updates to make it look more modern. The only reason I bought FIFA 16 was that I play manager career almost exclusively, and the player training was a huge draw for me.
Well, damn, now I really want to buy Fifa 17 even though I didn't wanted to support EA. What you guys think about this new mode, made some research and it look pretty interesting to be sincere.
