Honestly without counting the actual score, I would say, Fullham + West Brom + Brighton + Newcastle are good candidates to be relegated but Sheffield and Burnley ruined my calculations with their miserable performance at least until now 
It's only week 8 so Sheffield still has time for some to come if you expect it, but this is not bad luck or anything clearly their squad is not strong this season somehow I see the game is so bad whether this is some factor tooEven more, I cornered Burnley who will enter the degderasdi zone this season but in appearance no one knows so this is just my speculation.
