“Humanity seems to have a built-in regard for symmetry. It was what William Blake admired in the tiger and it explains, various surveys have claimed, why certain faces are considered more attractive than others (Denzel Washington and Cate Blanchett, apparently, have the most symmetrical faces in Hollywood). The instinct with football teams and formations has always been to set them out symmetrically – a 4-3-3 with the shuttling players neatly flanking the anchor and the wingers placed precisely on their touchlines, or a blockish 4-4-2 that becomes two lines with a line half the length set centrally atop them.” Guardian – Jonathan Wilson
