Is there a multiplayer option for Manager 2002? I haven't bought it yet and would like to know. Also, is multiplayer supported on 2001?

I think that the answer is yes.
I buy the game, and it's not like a german version.

You can have up to 6 players in a game in both 2001 and 2002.
But if one of you get sacked, then that player will not be able to play as another teams manager.
