Leicester City boss Craig Shakespeare has not been surprised by how quickly Huddersfield have adjusted to Premier League life.
The Terriers have taken seven points from their first four matches.
"It will be a really tough game, make no mistake," he said.
"In terms of momentum sometimes coming up the way they did, they have the momentum with them, in terms of their performances, they had a disappointing result against West Ham.
"But no they, haven't surprised me."
