That's an interesting question. I would say:
Liverpool
Arsenal
Spurs
Everton
Villa/Swansea
I know Everton are our rivals, but I think want our rivals to be relevant (but finishing below us). I'd really like to see the oligarchy of the top flight broken up. It would be good for the league and the balance of power would shift in a way that's a lot more, well, balanced. Clubs like Everton, Spurs, and Villa should be relevant again.
United, City, and Chelsea finishing outside the top 3 could spell an end for the silly spending. It would mean that the insanity that happens in the transfer market these days would finally come to an end, and the top clubs would be the ones with sound economic models. City and Chelsea's sugar daddies probably won't go away, but at least it would give other clubs a more level playing field.
That would be the dream sinario for me! The return of the real football clubs and the end of the mega rich plastic club. I don't want football to be someones play thing.
