Soccer Games For Wii

I have a wii (which can run gamecube games) in my dorm room but no really good games I can play with a bunch of friends on the same wii.
I was thinking Sega Soccer Slam (had a bunch of fun with that back in the day)
Time Splitters 2 (also a good gamecube classic)
but then I want a new game, maybe a shooter, maybe CoD5, is that multiplayer on the same wii?

Any ideas for good wii or gamecube games I can play with other dudes?

and if you say "get an xbox" you're a douche, I don't feel like spending 300 bucks or whatever it is.
