What do you want to see in FIFA 09

Okay, so I'm new to the FIFA games. I just got a 360 and am finally getting the hang of FIFA 08.

But I haven't gotten into manager mode yet. I want to play a "season" (Chelsea is my team, I'd love to do a premiership season) but I can't figure out how to do that. Do you have to go into manager mode?

(Sorry if that's a dumb question, it just looked complicated so I haven't started with manager mode yet).
