The problem I see there is they would want to expand the start numbers and dilute the initial quality. Groups are always subject to spoiling tactics but at least it keeps it as close to Europe's best as possible. I'm all for having teams that finish first play against teams that finished second and I also agree keeping teams from the same country apart after group stage should be looked at. I doubt it will change though...the last thing they want is Barca v Real Madrid early on. They seek glamour from the group stage and will do what they can to ensure the safe arrival of some late on in the tournament.
