Not a worry for us .. if you look at our last 7-10 seasons, we have been more consistent that at any time in modern history of the club.
Leicester as other said, had a fluke run and purple patch for multiple players on the right season where other sides underperformed, all wrapped up into one.
This year, the rub isn't going their way, they themselves have forgotten that they are nothing but a mediocre team who's every success was dependent on every player giving their all. The lack of application, improvement in league and normalizing of luck has pushed them down, and the lower position after the high of last year has drained confidence ... they are in a death spiral right now.
