Mourinho said before first game of the season, that the league would be a lot more competitive, lower points total for title, smaller teams upsetting big clubs, the standard across the board has improved.
I think it's played out more than he ever expected, but most the traditional top 8 sides have struggled and are comparing themselves to Leicester or Spurs in anger. No one's comparing themselves to last years champions who fell on their sword with much the same squad and setup.
Everyone else has had injuries, had key players settling in or have just been inconsistent. Only a handful of settled sides or sides that started and finished season with same players.
Our league challenge derailed over the winter and never got back on track.
