Leicester and possibly Blackburn aside every winner of the Premier League title for as long as I can remember has been playing European football.
I literally think that because Liverpool came close in 13/14 it perpetuates the myth.
This year Chelsea will win it because they have the manager that has put together the most organised lineup and tactics. Generally speaking, and I'm sure the Italian members of the forum will agree with me, the Italian style of management is suited to the English game which explains why 4 Italian mangers have won the PL (if Conte is successful this season that is).
Next year the winner will be one of the current top 6 who will all be playing European football and that should hopefully lay waste to the myth.
I'm not saying it doesn't have its advantages, it obviously does. But those advantages have become grossly overstated.
