I really like the idea of icon player careers, it would be cool to play as Beckham at Manchester United or bring Hazard back to football for a few seasons.
Another thing I like is social media like what we had in The Journey.
Origin stories could also be super cool.
The new player roles system could be really interesting aswell.
Next, live start points. These might be one of the most interesting parts of FC 25 career mode.
Finnaly, the youth academy is now so much cooler, not only do players apperances change by age now, but you can even play youth academy matches.
One thing I hope is announced is and update to international management, so you can start as an international manager like Deschamps or Carsley.
Also, make it so that managers can transfer like players.
