Some key players are gone (at least partially) and you can't transfer them to other clubs for your pleasure. For example, Schmeichel and Chilavert play in no clubs (and can't be transferred from their national teams - Chilavert doesn't even have one!).
I know you can copy their abilities unto someone else, but that would lose their "secret abilities".

Anyone?

Secret abilities? what is that never heard of any secret abilities...

Secret abilities - i don't know exactly, but here's an example:
Kluivert from Barcelona he has the strongest shot, he can score from a very long distance.
You realy can see the ball flying very fast.
The other players even with 7 in shooting
can't do the same (i have never see).

PS:exuse me for my english.

Sella,
I agree- there does appear to be hidden player attributes in the game. If you use Tal B's ME99 to look at edited players, you see ratings that are not present in the game. Of course ME99 was designed for F99 and therefore the numbers don't lineup appropriately with FIFA2000, but they are still there and must do something in the game. I'm wondering if player height is one of them...
