2010-11 shirt is personally one of my favorites.
When I think of clubs, some kits just stick out to me.
I think of Manchester United with the big AIG sponsor during Ronaldo's initial stint. With Chelsea, I always think of the "Samsung" sponsor with players like Drogba and Ballack.
Even with players, when I think of Buffon, it's the 2006 World Cup red and gold Puma kits that stand out to me and are legendary
With Bayern, it's the red kit with gold numbering/stripes that they had when they lost to Chelsea in the final. To me, those are the peak Bayern kit that stands out to me this century. Why they haven't gone back to that model/color combination, I have no clue. I also liked the old T-Mobile logos better.
