I feel that a new "tier" of the Premier league is getting solidified. People often talk about the top six, with Everton being #7, and then there's teams below them that are mostly rather unpredictable. But right now i feel like the likes of Watford, Leicester and Southampton are creating their own "Mid-table" tier. I'd expect Newcastle to be a part of it sooner or later too. I still have many questionmarks regarding Burnley but maybe they can join it too. Could Everton sink down to this tier? Possibly, who knows.
I think it's interesting and all, but I really hope that the Premier League doesn't turn into the next Serie A sooner or later, where promoted teams have a very hard time not getting relegated immediately.
