Hmm, I never had a favorite team until I really started watcing football religiously (like all the televised games available every week). Around the beginning of my high school days that was. I fell in love with Arsenal. Their play at times can be absolute magic, at others, so heart wrenchingly disappointing. I started following them around early 07, so I didn't hop on to the invincibles band wagon. Throughout these last 4, and actually, last 6 years, they have yet to win a piece of silverware, but they will be my favorite team regardless. This season may have been the most disappointing one yet IMO.
Obviously being a Gunner, I can't support any other English side hahaha. I do have a team that I 'like' but not necessarily support, from each of the major leagues. FC Dallas, as they are from my hometown (Went to almost all of their home games last year before they made it to the MLS Cup Final, which was BS). From Germany, I've liked Dortmund, long before this season lol, I still have some of their Nike branded training gear. For some reason, I have a soft spot for Atletico Madrid, yet I also like Real. Quite terribly, they are heated rivals, but I've visited both of their stadiums and been to a RM game, so I feel like I have some sentimental connection (If that means anything for someone who doesn't live in Europe). I liked Juventus from their glory days before the Calciopolli Scandal, Del Piero and Nedved at their best
Now they are quite sh*t, a disgrace. Obviously, in International competitions, Arsenal is my team 100%. I guess you could say, I just like watching those teams in their respective leagues.
