Melbourne City (owned by Manchester City) can't wear City's usual all-blue home kit because it upsets Sydney FC, instead they wear a predominently white home kit.
I've mocked this up as some sort of compromise, using the thin gradated striping that Nike are using for the third kit for most of the teams they supply, with a transition from sky blue throgh to white. It keeps things mostly white (paired with white shorts and socks), but give City back its blue. Sydney FC would probably still hate it.
