I hope they get some common sense things sorted out for manager mode, I'm playing Fifa 09 now, and it seems the CPU doesn't pick a team at all, for example, I've completed most of the England League signings, taken players out and adding new ones.
Now, I've noticed some of the teams have some of the youth players in the team, or reserves, with Man City it's more noticable. There's also the fact that I've seen Drogba's stamina bar at 5% at the start of the game, this leading to some very drastic England League tables due to weird results. Atm, 12 games in, I have Man U at 5th, followed by liverpool, then chelsea at 9th, and arsenal at 14th... And they were rock-bottom of the table about 8 games in. The results going on around me don't seem realistic, and the AI managers don't seem very good.
I also hope that changing numbers is included in manager mode, I'm sick of players being brought in and being stuck with numbers that I don't want them to have, in another mode I had brought Steven Gerrard to Sunderland (playing on an easier setting as well btw at that time), he got stuck with 47 I think, and had it for the 2 seasons I had played with him in the squad.
I also have little gameplay quirks that pretty much related to how the computer can't measure how important a final 10 minutes are, and I'm stuck with players who can't get the ball out of their feet quick enough to have a nice flowing attack.
that said, from what I'm reading, some of these little quirks I have seem to be made better, as I'm also one who got sick of the ball going into slow-mo once it's in the air. Even more annoying when you watch the ball go in the air and have your forward have to wait in one place for the ball to come down, and I hope that if they do have to wait, that you at least see some forward/defender struggling for the best position to get the ball, they just stand there at the minute.
edit: I'm a bit disappointed that the transfers in MM are still week-by-week, I was hoping that during the transfer window you could have the option to go day-by-day to have a more realistic transfer window, because of how it used to be, I would occasionally only come out with one player but have about 10 targets
