I I found nothing of the sort, but I also have some perspective. If you think Leicester is a lesson to the rest of the league, then I can't help you. A few players had worldies this season, good for them. I guess that makes Spurs, Arsenal, City, United, Liverpool and Chelsea all mug teams? Those six teams are the cream of the English game and they ALL came up losers to a hard working team with no superstars....and that has happened once in the history of the premier league. I wouldn't plant your flag on that comparison.
And, whenever I hear the words "with all the money we've spent," I generally close my ears to the rest. It is a nothing statement. We have had to pay over the odds for players in order to attract the best talent possible to a perennial second tier team to make it a top four contender every season. Now, we are going to have to pay it to bring truly world class players to the club...just like everyone else in the top leagues of the world has had to do! In some leagues, there are only a handful of clubs who can afford to do it, and they are always the top 2 or 3. In England, we have a "Top Six" (see above) and this year Leicester (and even West Ham to a certain extent) have crashed the party. However, expect four out of those six every year for the foreseeable future, which means two top teams are going to miss out on the CL every year, and maybe three if English teams don't start to do better in the competition.
