Huddersfield's dream run continued with their Premier League debut with a 3-0 win over Crystal Palace last Saturday and Wagner is hopeful of getting a win when his team host Newcastle in their first home league game.
"I am very excited about Sunday's game. I'm sure it will be an extraordinary atmosphere against Newcastle," Wagner told reporters on Friday.
"We will have to get the little details right against Newcastle. We have to be totally focussed. It's important for us to get points on the board and to put in a good performance."
Forward Nahki Wells is ruled out for another five to seven weeks as he recovers an ankle injury, and midfielder Jonathan Hogg could return from his ankle injury after the upcoming international break, Wagner said.
