Unless you are one of the big four, whose long term future in the top flight is assurred, or among the next three or four who are safe in the medium term, the Premiership is a miserable place best avoided. At least half the season is spent looking over your shoulder at the relegation zone and every few years you get caught up in the dogfight to avoid the dreaded drop, which means you will be stuck with bugger all income and a squad on highly inflated long term contracts.
Promotion into the top flight will prove to be a poison chalice almost certainly for Stoke and Hull, and probably for West Brom. Two of the three who came up last year have gone straight back down, and the third spent 45 million quid to finish three points off the relegation zone.
