At this very moment:
+ The new training looks good and appealing. It really adds something to work on when you don't have anything to do.
+ Visually ok
- Real time matches notification shows a manager picture, but no name or team name. It's not actually clear who's playing if you want to watch the game
- Referring to % instead of cones for quality may need some time to get used
- Many details aren't easy to see at a quick glance like it was before, like morale, precise condition, SA
- Missing the option to take over a new club (where is it?)
- No more team history option and historic stats
- A real trophy room where you can see them all together and not only by season
- IMHO it doesn't fit on a desktop, it's ok on a touchscreen mobile, but not on PC
EDIT:
- Having the next upcoming match on top of the screen all the time was better than having to press home everytime
- Now you can't see how many days a player will be out for injury by just hovering on the injury icon. You have to click on the player and see.
