A more likely outcome would be Abramovich discovering a way to replace the fans with more agreeable versions. Don't think he hasn't thought about it...
I think it varies constantly and depends on taste. Leagues do have differing styles of play and viewer experiences. In terms of attracting talent, the Premier League is definitely near the top. But I feel like England is well behind in terms of the way it is run and the quality of the fan experience. Germany is unquestionably tops in those areas. Spain is the least competitive overall, with England next in line. There is more battling at the top but Man U and Chelsea still own the league (mostly the former). Man City is muscling in, but the difference is small. Italy has a high standard of play but very serious problems with ultras, and to put it bluntly is by far the most corrupt of the major top divisions.
France and the Netherlands are a step down in quality, but the games I have seen have demonstrated a good standard of play, and both leagues produce a lot of top talent.
Finally, (and slightly off-topic) speaking as an American, I'm surprised at how much racism and bigotry I see across European football. Countries like Spain and Italy in particular seem to have serious culture-wide issues with open bigotry being accepted as normal (and lets not talk about what goes on the Balkans). In England the problem seems more drink-related than anything else, but recently racism has become a hot-button issue there too. The US has
plenty of problems with this stuff too, but our
sports are far, far more progressive and proactive in taking a zero tolerance approach to it. Monkey chants and Nazi salutes simply do not happen in the US.
That's my 2 cents.
Holy cow, almost £450?
