The Midlands outfit experienced a torrid first half of the campaign and currently sit in the relegation zone of the Premier League table on 19 points.
"We have a strong atmosphere in the club," N'Zogbia told the club's official website. "Everybody is happy and everybody wants to play. We just haven't been getting the points.
"I'm confident that the way we play we're going to get wins soon enough. The good results will come soon. We all get on with each other, there are no arguments, we are all working as one together. We are going to start winning."
Villa go up against West Bromwich Albion at The Hawthorns this Saturday.
