I think this things shoulld be in FIFA2000:
1. Three ref's
2. That the ref is showing the yellow card
3. That the ref's look, not is the same as the goalkeepers!
4. A bit larger fields
5. Names and sponsores on the shirt's
6. More realistic player trading, for example: U can't buy and sell for the other team's. And the other team's shoulld have buyed a replacement if they sold someone.
7. U shoulld see the coach!
8. If it's snowing or raining I think the players shoulld be dirty!
9. I think it shoulld be easier to score outside the 18 yard box!
10. It had been cool if u may continue playing after a season and maybe qualify to some cup's!

They are all right but i want to add something on the list if you don't mind which is the bench.!
We need to see the players and coaches looking at there players playing.
and we need to see the substitute players also.

The main thing that FIFA 2000 needs is being able to score from outside the 18. It also needs better fields.
