The Terriers failed to score for the 12th time in 16 away games as Newcastle United claimed a precious 1-0 win.
“From day one when we met in pre-season, we have known it will be a good season after 32 games if we are in a position to fight to have another season in the Premier League,” said the Huddersfield chief.
“This is exactly what happens. So far it was a good season but we would like to get over the line and to do that we have to use our opportunities.
“There is no doubt we have to score goals. The spirit and this effort and attitude, that the players always bring to the games gives me confidence. I think we can get this over the line.”
Town sit above the dropzone with 31 points from 32 games. Wagner added: “For me I am not worried about how many points. I focus on our performance. Defensively, the second half was one of the best of the season. What should I moan about?
“I moan we have not scored and brought real pressure on our opponents. But I cannot be too critical. This effort and attitude is exactly what we need to get over the line.
“In the next game (at Brighton), another very important one, we have everything in our hands and, hopefully, we can get a better result.”
