There have not been any real great upgrades from previous versions.
The newest game in the FIFA series keeps the familiar game engine that most players have grown to know and enjoy - this years has completely revamped statistics and rosters to keep up with the new season. Don't be surprized if you are a fan of the FIFA series and do not notice too much added on from last years game. It seems like companies have forgotten about trying to update on "Older" systems such as this.
However, any fan of either the sport or the series will really enjoy this game. It has everything that a soccer fan would love in a game and then some. And after all of these years, they certainly have it done well.
