Bar Celtic and Rangers, I haven't heard of anyone wanting to move leagues (and I imagine there are a few - the likes of Anderlecht, Ajax, Rosenborg, Skonto Riga, Lyon would be prime examples of clubs who could well feel they have outgrown their league), which would by exntesion mean you wouldn't have heard of many clubs not being allowed. The most likely reason I see for this is that they simply aren't allowed and they know it. UEFA and FIFA have oftentimes stated their opposition, but I don't think I've ever heard the legal cases Steve's referring to being mentioned by anyone - the clubs concerned, media, etc. Doesn't mean it's not there, but I'm sceptical nonetheless.
