Without significant changes in personnel and, of course, a top manager, we're still competing with West Ham, Southampton, Stoke, Leicester (pre-occupied with Europe) for a top 10 finish..
So, in order to do a Leicester (or top 4) we might need:
1. Good manager
2. 3-4 major signings and limited/no loss of key players
3. Good run without injuries
4. Set of favourable fixtures (see Leicester - had a tough run mid season and avoided Everton (then decent), Liverpool, City and a few better sides for quite a while - got fed a decent set of opening fixtures - Sunderland, Villa home for example, Bournemouth, West Ham (away) and took advantage..
If one produces some sort of index of expectations you have to put
Man City - Chelsea (presumably rejuvenated) - Arsenal (probably), Liverpool (possible), Spurs (likely), Man Utd (possible) - in the top 6
West Ham, Leicester, Everton, Southampton, Stoke (probably) next 5
Sunderland, West Brom, Palace, Swansea, Watford, Burnley, Boro, Bournemouth, Other Promoted side - lower half
West Brom, Bournemouth (2nd season), Watford, promoted sides most likely to be the shortlist from which three will go down
We'll do well to join that front 6 surely.. though one may drop away leaving a chance of competing towards top 4.
