Speaking to TNT Sports after Saturday's 2-1 loss at Aston Villa, Haaland said: "First, I'm looking at myself. I haven't been doing things good enough, I haven't been scoring my chances. I have to do better, I haven't been good enough.
"Of course, our confidence is not the best. We know how important confidence is and you can see that it affects every human being. That is how it is, we have to continue and stay positive even though it is difficult."
