Saints had to withstand plenty of pressure and quality attacking play from the hosts, and Cunningham felt that his team showed real character.
“We came through a lot of adversity,” he told his club’s official website.
“You can’t practice what we did out there; you just put your faith in a group of players to do their best and they genuinely gave me all they could. Today they showed what they are made of.
“I have been involved in wins that come with adversity. They sometimes are your best ones and I said that half time that we would remember when and where these two points came from.
“These could be the ones that could get you to a particular finishing place. It was a massive victory for us.”
Cunningham is also pleased with the way that the early part of the season has gone for his team.
“It’s been a good start to the season. We spoke about starting big because of the new system and we have done that,” he added.
“I would prefer more performances like Salford away but I am more than happy with what they are doing.”
