Salford were beaten 22-8 by Warrington in their opening Super League fixture, but Cunningham believes that they pose a threat.
“I went and watched the Salford v Warrington game, and I thought they were good,” he said.
“They were only a couple of tries away from a big upset.
“The game was always on a knife edge for long periods. Warrington converted their chances, but Salford didn’t quite convert theirs.
“But they created a lot of stuff, and Michael Dobson looked really good in the second half.”
Cunningham also feels that his former Welsh international team-mate Iestyn Harris has plenty to offer as Salford coach.
“Iestyn’s a good choice, and he’s come through some good structures,” he added.
“His understanding of the game is very good, and he’s got some very good players.
“His halfback pairing alone is probably to be admired by the whole competition.”
