I Have Few Ideas.
1. More interaction with the players during a match. And you could tell the players your about to bring on to warm up before and tell them what you want from them or anything they want any of the players to do on the pitch like they do in real life if a sub comes on and talks 2 a player.
2. more media,player,manager ect interaction, like more vary of comments to make.
there just 2 ideas because there isnt much more they can do 2 make it a better game than it already is, or atleast what i can fink of
