Sunderland boss Gus Poyet is stunned by the lack of confidence from his attack.
Sunderland drew 0-0 with Norwich City yesterday.
Poyet said: "I expect somebody to score. It doesn't have to be Ki all the time, but it has to be somebody.
"The decisions in the last 30 metres today were scary, and that was unexpected - players who needed to have a shot, taking three touches, players who need to take a touch, they try to shoot, back to goal.
"I didn't expect that. I have got no explanation. Now if we make a mistake, I can tell you why, but there were things today that happened on the pitch that are difficult to explain."
