I gather that by saying that Northern Ireland, Scotland and Wales would have no involvement, they are protecting themselves from FIFA claiming that since Great Britain was represented by one team in the Olympics, then they should be represented by one team in the World Cup.
Too bad that only England is involved, because at that level, an Under-23 team (with three over-age players), there would a few players from Northern Ireland, Scotland and Wales, that could make that team.
Not sure if that will help them if FIFA do get around to debated this issue for real. There is a number of people in FIFA who would vote in favour of limiting Great Britain's representation to one team.
Have to say the scariest part of that article, was when they were talking about a successor to Blatter and they mentioned Jack Warner of CONACAF. They didn't actually say Warner will follow Blatter as head of FIFA, but just to have Warner's name in the same paragraph talking about successors of Blatter is frightening. Warner is a bigger idiot and certainly a bigger crook than Blatter.
