If there is one good thing Liverpool have done...
..it is cleaning up their badge. Arsenal's logo/badge/crest isn't awful by any means, but with such a strong symbol like the cannon synonymous with the club, why not simplify the badge to just that?
Look how beautiful and simple it looks on the shirt http://www.toffs.com/content/images/thumbs/0010094_arsenal-1970s-short-sleeve-retro-football-shirt.jpeg
I know you all agree right? :)
