Umbro pays FIFA a bucket load of money probably
as to roses on shirt for rugby, rugby is not part of the Fifa or FA remit, thank God.
as to approaching FIFA, probably dumb but with the "hostility" between the FA and FIFA post the World Cup bid, they may feel that this is a battle not worth fighting.... FIFA do have a point as one could see all sorts of issues with Iranians putting anti Israeli slogans on their shirts, or a country putting a pig motif on versus an Islamic state.....and all the rest.
The solution is in what they are doing - wrapping the poppy around the event re tracksuits, the pitch, the screens, a minutes respect etc etc and then medium term take it up with FIFA with the backing of the Home Unions, the Commonwealth, the States and the Germans........
Its all got a bit out of control or the proverbial Mountain out of a Molehill.
