Whether we get promoted or not the defence will need rebuilding.
We will have only three premiership standard defenders in Chester, Elmohamady and Taylor, that's assuming Terry will not want another season.
Hutton and Samba are out of contract, while Richards, Elphick, DeLaet and Bree aren't of the required standard, (although Bree is young enough to improve).
Proving how shortsighted the decision to sell Baker was.
The centre of midfield, the defensive and holding, (box-to-box), positions are of paramount importance.
With Jedinak succumbing to injury, as well as age, expecting him to play up to premiership standard would be too much. While it looks like Whelan has shot his bolt.
The wide midfield positions are probably good enough.
With the emergence of Keinan Davis I think the forward line could do a good enough job in the premier league.
