Only Juventus...
I do have a few 'preferences' or soft spots, but it's not like a scream and shout while seeing their games and check up their news etc...just watch their games if I have the time...
In France I've always liked Bordeaux. In Spain, Athletic Bilbao and their all Basque side, Scotland - Aberdeen, although
I look forward to the Old Firm derby and always mark that on my calendar, one of the best games to watch as a neutral.......pretty much it. I watch alot of EPL, and generally cheer for any underdog playing vs. the big four (Man U, Arsenal, Liverpool, Chelsea).
Football. Can't get enough.
But for sure, Juventus + Italy for well over 10 years is the only team that has made me jump around the living room / pub / coffee shop in joy...or in despair.
