Bendtner has made an impressive start to life with his new club and struck up a good understanding with Stephane Sessegnon in attack, but he now wants to help Sunderland improve on their current position of 16th in the Premier League.
"How do I think it is going at Sunderland? We have great players here. It is down to us to prove that and not just talk about it," he said.
"We would rather show on the pitch that we should be on the other side of the table. I am sure we will in the weeks to come after the international break. We are good enough and strong enough, but we just need back- to-back wins."
Bendtner added: "You can see Sessegnon and I are starting to gel together. We are trying to find each other, look for the balls to put one another in training.
"We put a lot of work in to see if we can find the runs and the goals we do in training. I was delighted to get my first goal. Sessegnon pulled it back, I saw the tackle coming in and I hit it.
"It took a deflection and it went in. It was a relief. It is always special to get off the mark.
"It was always going to come at one point if you keep putting yourself in among the chances."
