Arsenal best bet to win it at the odds available, Chelsea still most likely though.
I think this year the promoted sides look better equipped to stay up than the last few years, so I'd go between Leicester, Sunderland West Ham and one of them (guess Norwich?) to go down.
I think West Ham will really struggle, worth a bet to go down in my view. Quite a poor squad that overachieved last year, striker injured, Europa League to contend with.
