Them winning the league will be fully deserved and a good thing if indeed they do it. I don't subscribe to the theory that it is a fluke as they have unearthed 3 very good players in Vardy, Mahrez and Drinkwater. They have a manager who has made them incredibly difficult to break down and they have maintained form and won ugly where needed. It's hard not to like what they have done. If they keep this bunch of players together, they could have a good season again. But, lose any of them or have any of those players feeling complacent then they won't.
We've done all of that but had the added Europa competition that has impacted our league form. But if you want to be a big club, that's what you have to deal with. Every season is tough, but the EPL is a different beast to every other league byvirtue of how competitive and relentless it is. No winter break, no help with fixture congestion, and no easy games (bar Villa). Even the most experienced managers struggle with it and that is why I'm not overly worried about Guardiola, Lowe or Conte. Teams have to fight every game, every time or they will get punished. That is where style of play, and the hardworking of players will overcome skill alone more often than not.
