The Gunners' looked to be getting their season back on track with four consecutive wins prior to their clash with the Saints, but they failed to sparkle against Nigel Adkins' men and were fortunate to leave the St Mary's Stadium with a point.
With Everton picking up all three points against Newcastle on Wednesday, Arsene Wengers' men currently find themselves 6th in the league table on 34 points, four points behind 4th placed Chelsea.
However, Vermaelen insists his side's failure to pick up all three points against Southampton was nothing more than a minor blip, expressing his belief that the Gunners would fire again in their remaining games and secure qualification to the Champions League come the end of the season.
"We are disappointed with the result, with the way we played, but I think we have to stay confident and the spirit has to be good all the time," Vermaelen told Arsenal Player.
"It's true [our form is good], of course we want to win every game, that's why a draw is [disappointing], but we didn't lose and before we won four games.
"In the league everything is really close, everybody can win against everybody. It's a tight race and we are confident."
The Belgian international nonetheless acknowledged that the Gunners played poorly against the Saints and claimed significant improvements in his side's performances, especially in defence, were needed.
"We didn't play our best game [against Southampton], we didn't create a lot of chances to score goals," Vermaelen added.
"Even the goal [we scored] wasn't a chance in my opinion. It wasn't a great afternoon.
"Wojciech [Szczesny] had to make a few saves, I think our overall defending as a team can always be better.
"I think the space between the defence and our strikers was too big so they could have play their game if they wanted.
"We have to work on that, it has to be better."
For now, Arsenal will turn their attentions to the FA Cup when they travel to the Liberty Stadium to take on Swansea on Sunday.
