I'm still keeping my possibly unreasonable undisclosed location policy here on steemit, but can tell you that I have no real personal connection or bias towards the countries mentioned in this thread. Also I wouldn't say I support a specific team in particular nowadays. There are multiple teams I have sympathy for and I just want to watch interesting and exciting football played by technically and tactically astute players managed by smart and inventive managers. Stadiums with atmosphere and history are also something I enjoy.
The league I follow the most is the Premier League (as it's the most interesting and competitive and currently has the best managers) and I also try to keep up with the Bundesliga, La Liga and Serie A and to a lesser extent Ligue 1. And of course the Champions League and some Europa League.
