Where/how can I watch (non-MLS) football matches in America?

[Drew]

I have recently become a big fan of football (soccer) and am having trouble finding out what channels/websites/etc. show football matches from the various leagues in Europe. I'm interested in any Premiership matches, as well as, matches involving Barcelona, Celtic, Ajax, and Juventus. Do any American channels show games, or is my only way of seeing them by purchasing a satellite package (and if so, do the satellite packages show games from all different leagues?).

Thanks in advance for any help.

P.S. - I am aware that it is not currently football season, I am merely preparing for the upcoming season.
