Best football (soccer) team

What team in your opinion is the best soccer team in the world. Name a country or a club. It has to be your opinion because otherwise everyone would know that Barcelona is the best and Spain is the best country because they won the championships. (Champions League and World Cup) Who is the best?

Well No doubt about it but my favorite team is Manchester United and I am very big fan of Sir Alex and his two old boys Scholes and Ryan Gigs. Rooney is my Favorite attacker in the team but I admire mostly these two old guns who are the king makers of Man United.

Jagiellonia Bialystok, I'm patriot. ^^
Seriously, I think best club is Barcelona. I'm not their fan, but they are really the best and they showed that by won Champions League.
