According to FIFA this feature will allow you to customise 6 different team sheets per club and alter you formation, tactics, and roles based on on your next opponent. You can also assign player instructions to fit your system and change the game.
This is great news for all FIFA fans. I am sure you all know what it's like trying to keep any more than 30 players happy, even with playing in 4 competitions. It's going to be great to have different formations, players etc so you can have an experienced team for your league and Champions League games, and younger teams for cup games. This feature is also important for youth development, which has also been improved for FIFA 15.
Over the last few days EA Sports have released the top 50 rate players for the game. I bet you could never guess who is rated at number 1? Yes, it's Ryan Shawcross. No, it's obviously Lionel Messi. Personally I believe it should be Cristiano Ronaldo but considering Messi and EA Sports have a partnership it will never happen.
I doubt there will be any more major news on the game that hasn't already been released. Other big things that were announced were mainly to do with game mechanics, my favourite tweek being the improved AI in goalkeepers. Hopefully the mechanics work perfectly fine. How often have you experience a goalkeeper come out to make a save, or commit to diving in one direction? That should no longer be the case with the new improvements.
The FIFA 15 demo is released tomorrow (09/09/2014).
