Asked about Daniel Farke's side at his press conference today, explained why they will pose a threat tomorrow.
"They have their style and they stick to it," said the boss.
"That's the right way. They came up playing really good football. They're a very good team with a very good manager. They have got the players and the belief in the system.
"In terms of their recruitment as a club they're a great act to follow for Championship teams. I have been impressed to see them carry on the Premier League with that way.
"We go to Norwich wanting to win the game but also very respectful of a team that were on the wrong side of a defeat that wasn't the story of the game against Liverpool, and played very well against Newcastle.
"I know them very well from the Championship last year, which is helpful in preparation but also makes me aware of the dangers."
