The recently promoted Bluebirds will play David Wagner's side at The John Smith's Stadium this Saturday.
"That's another miracle story, what they've done is unbelievable really," said Warnock.
"But it's good for us. We look at what they've done and we want to do what they did.
"Now we've got the squad together I think we can be more optimistic travelling away from home.
"We're going to take one or two drubbings, but everybody is in this league. We have to just make sure we don't read too many newspapers when things aren't going so well and stick to the task.
"I think this can become a fortress. Even the top six sides I don't think will enjoy coming here."
