As I understand it, the European powers-that-be (especially Sky) had no kind words for Leicester's title run. I think it was that piece in The Independent (but I've read it elsewhere) where major players have talked about "we don't want too many (read - any) more Leicester Citys" - it's absolutely meant to be a closed shop, where the same teams play the same opponents, year after year.
At some point, everyone else just needs to put their foot down and call these assholes' bluff re the Super League. Because it's a de facto Super League now.
The knives will 100% be out for Everton. For Christ's sake, we haven't even made any major purchases. Just an elite manager, and the fainting couches are filling up.
