Now the Devils face Romanian outfit Otelul Galati twice in a row - first away tomorrow (Tuesday), then at home at the start of next month.
"We need to win both games [against Galati] and hopefully we'll do that," Ferguson told the club's official website. "And we'll hope for one of two things from the other teams - either they both draw or one wins both games. We don't want them to win a game each as the group would then be very tight."
The manager admitted that he had "never heard of" Galati prior to the tournament but has since done his homework.
"I had no idea where they were from," he said. "I don't know if they've changed their name like a lot of European teams but I'd never heard of them.
"We know plenty now and know enough about them. We've got all the videos on them."
