As regards the edit I disagree because of what Rafa left behind, that's the point.
Granted Bruce might be a total catastrophe but he's took on a much better squad than McClaren did. Imo.
They have a good keeper and potentially goalscorer that could keep them up.
If anything happens to those two they are nailed on to go down.
Dubravka's form could dip anyway as he will be disillusioned as to what's going on and probably wants away, a bit like what happened to Shay Given, he won't be the same player now imo.
