More of the bleedin' obvious.
I fancy Hull might actually want this more than Sunderland. Hull, it appears to me, will have no doubts about wanting to beat Sunderland 3 times this season - their killer instinct is definitely there.
I think (good) Sunderland are the better team, but there's no evidence yet to back that up. If Sunderland want it then they have to raise their game to similar levels as they did against Man City.
