At the back Richards, Clark and Lescott have been the principle embarrassments. In midfield, that honour goes jointly to Westwood and Bacuna, and up front to Gabby and Gestede.
Clark could have a good season next year, but he has had a rubbish one by all accounts this year.I think the Championship will require us to go with a bit of beef up front, or at least a bit of niggle and needle, some sort of budget Diego Costa. Ayew is our best attacking player, but centre-backs would be able to smash him into the stands with impunity in the division we're going into.
We shouldn't forget about Kozak. I don't think he'd score many goals but he'd look as class above in the Championship and would create space for others.
Next season will be the last of his contract, not sure anyone will take him off us before then considering his injury record here. Even on a free this summer I reckon it's unlikely anyone would bite.
