"We wanted to show that we are fearless. We remain the biggest underdogs".
Huddersfield next face a winless West Ham in London after the worldwide break.
The last time that these two teams met was in December 2010 in the third tier of English football - Southampton won 4-1 that day.
The Saints go into the fixture with the Terriers after a shock defeat to lower league opposition in Wolverhampton Wanderers, however, they have managed to take four points from their opening two league games.
"We'd like to sign Rob Green", Wagner revealed after seeing his side follow up successive league wins with a deserved point against Southampton.
Huddersfield are at home to Southampton in the Premier League tomorrow.
"He is left-footed, he's a type of player that we don't have and hopefully he can settle as quick as possible with the rest of the team to be available. It is different class, a different category in the Premier League". If the Terriers are able to win, though, they will be virtually a quarter of their way to safety too, an incredible position just three games into the season.
