TBH IMO we have as much if not more chance to win the league next season as we did this, and how much of a challenge we are able to mount will be determined by if AW does address all the known issues with the squad, and if he is prepared to adapt his style and squad management.
As it stands IMO LFC represent the greatest threat as the have no UEFA comp involvement like Leicester this season, and because they are 1 year ahead of the other contenders regarding their transition re change of manager.
CFC, Citeh & ManU will all need to rebuild & all the new managers represent a change to their current style of play, with 2 not having any prior EPL experience. In many ways this will be the biggest challenge in any of their careers simply because of the depth of competition.
Spuds, Leicester & WHam all need to improve the squads in order to be able to sustain performance in UEFA and the EPL.
That said all the teams in transition are capable of achieving top4, and just as for this season the title will not be won by simply turning up and relying upon stability and cohesion.
