Greatest sports team ever.... can't argue with New Zealand rugby being up there, the Dutch Football and field hockey team in a similar vein of a small nation punching above their weight.
The New York Yankees is always touted as the greatest ever baseball team and the Chicago Bulls with Michael Jordan (could be overtaken by the all conquering Golden State Warriors???)
And regarding Football, the tika taka Barcelona team cerca 2009 were close to perfection and the best team of my lifetime (1995-present)
